Hi!
Sorry for weird subject but was a bit unsure on what to call it.
Anyway, I have a WPF-form where I have some items below a textbox. I want the textbox to fill up the grid above the bottom controls but leave space for them.
<Window x:Class="SMS_Sender_3._0.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:SMS_Sender_3._0"
mc:Ignorable="d"
Title="SMS Sender 3.0" Height="350" Width="525">
<Grid>
<Border Margin="8">
<StackPanel>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Phone:" />
<TextBox Grid.Column="1" />
</Grid>
<TextBlock Text="Message:" />
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="225" />
</Grid.RowDefinitions>
<TextBox Grid.Column="1" />
</Grid>
<Grid Margin="0,3,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="150" />
<ColumnDefinition Width="60" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Mall:" />
<ComboBox Grid.Column="1" />
<TextBlock Margin="5,0,0,0" Grid.Column="2" Text="0/160(1)" />
<Button Grid.Column="3" HorizontalAlignment="Right" Content="_Send" Width="100" />
</Grid>
<Grid Margin="0,3,0,0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="Type:" />
<ComboBox Grid.Column="1" HorizontalAlignment="Left" Width="150" />
</Grid>
</StackPanel>
</Border>
</Grid>
</Window>
As it is now, the textbox will change it width but not it's height, due to it being set to 225 in the grid definition. However, I am unsure how to set the grid so that it will take up the space but leave the bottom controls visible. Basically I want it to be as it is now but able to resize.
I am thankfull for any suggestions.
Have a nice day!

When you put Grids in a StackPanel, the Grids "lose" their "star" (*) qualities since StackPanel do not fill available space.
You should put your Grids in a parent Grid instead of a StackPanel (if you want to make the most of "stretching").
I typically start everything with "*" or Auto; only afterwards do I (rarely) touch up with explicit widths or heights.

The purpose of this code is open image file in a page and display it in another page.
I had tried set ViewModel by using Singleton Pattern, but it didn't work....
If I integrate to one View, it can display the image correctly. But I need to separate the views.
I have no idea what's wrong in this MVVM code....and how to fix it?
Please point me how can I do or let me know what keyword I can search the toturial/sample.
Thank you all.

You've got a .Contains function with no parameter.

It uses String[].Any() to indicate the parameter.
The problem is it can't display selected image file on DisplayView (page)....
As my original post mention, all the same code can work well in one ViewModel and one View.
When I separate the code to one ViewModel and 3 Views, it can not work as my expected.
It just can show open dialog for selecting file, but display nothing after selection.
I think the problem will be the operation on one View(DisplayControlView) can not effect another View(DisplayView)

I use code-behind to load images; that works.
I also hook up the "ImageFailed" event; then you know why it's not working (somewhat).
(MVVM has too much "indirection" for my brain).

The problem is that your DisplayPanelView is setting its DataContext to a new instance of your viewmodel. The image path you set on the DataContext of the DisplayControlView will have no effect on the property of the separate viewmodel instance used as the DataContext for DisplayPanelView.
You need both controls to use the same viewmodel instance for their DataContext. Depending on how your ReviewView viewmodel is set up, you probably want to expose a single DisplayViewModel instance as a property on that viewmodel, and have both Display... views bound to that.
For example:
public class ReviewViewModel : ViewModelBase
{
private DisplayViewModel _display = new DisplayViewModel();
public DisplayViewModel
{
get { return _display; }
set { SetValue(ref _display, value); }
}
} ReviewView.xaml:
<views:DisplayControlView DataContext="{Binding Path=DisplayViewModel}" />
<views:DisplayPanelView DataContext="{Binding Path=DisplayPanelView}" /> Remove the <Page.DataContext> from both DisplayControlView and DisplayPanelView pages.

Here is something can't run properly. Is below code is written in NEW class called ReviewViewModel?
public class ReviewViewModel : ViewModelBase
{
private DisplayViewModel _display = new DisplayViewModel();
public DisplayViewModel
{
get { return _display; }
set { SetValue(ref _display, value); }
}
}
But the Intellisense will show warning about the declaration of DisplayViewModel and the function of SetValue is invalid....
What prerequisites are needed for this code?
Sincere thank Richard Master to point me!!
All Views need one ViewModel instance, and I had no idea about how to set one ViewModel instance until this post point me.
And thank Gerry join this discussion.

In addition:

<Grid Background="{DynamicResource ThirdHueLightBrush}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="280"/>
<ColumnDefinition MinWidth="690"/>
</Grid.ColumnDefinitions>
<Frame Grid.Column="0" Source="Frame/DisplayControlView.xaml"/>
<Frame Grid.Column="1" Source="Frame/DisplayPanelView.xaml"/>
</Grid>

One thing I see right off the bat is that when you use DataContext you are instantiating DisplayViewModel.
<Page.DataContext>
<vm:DisplayViewModel/>
</Page.DataContext>
You basically created two instances of DisplayViewModel.
One fix would be to instantiate it somewhere else in C# :
DisplayViewModel displayViewModel = new DisplayViewModel();
Then add to each page then for each page in C# on initialization add:
this.DataContext = ????.displayViewModel
Now they will both point to the same instance.
So many years of programming I have forgotten more languages than I know.

Thank for point me.
Actually, I had solved this problem a few moment ago... XD
Here is my solution:
1. Using singleton-pattern to fix one execution instance
2. At each View code-behind(???.xmal.cs) which needs to using the same ViewModel, I add below code
this.context = viewmodel.instance
BTW, I also ask in below Taiwan IT forum......and self-question at below to show my detail solution XD

I have also seen static's used. Not a "static" fan but it works. Static's have there place. The reason Serilog is so easy to use and hence popular is because of static's.

I have a simple login window with Company, User Name, and Password. There is a Remember Me checkbox, and if the user checks it, then I pre-fill in the Company and User Name the next time they run the app. In that case, I want to set focus to the Password field.
In the Window's XAML I have
FocusManager.FocusedElement="{Binding FocusedElementName}"
Then in the VM I set the FocusedElementName property to either "company" or "password."
The problem is that the focus is not being set. The code behind is working as expected.
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

The problem is that you're setting the Path of the binding. The FocusedElement property relies on the ElementName of the binding:
FocusManager.FocusedElement="{Binding ElementName=firstButton}" You can't bind the properties of a binding, so you can't do this:
{Binding ElementName={Binding ...}} Short of using the code-behind for the view, the simplest option is probably to use a style with a series of data triggers, as shown in this SO answer[^]:
<Style>
<Style.Triggers>
<DataTrigger Binding="{Binding FocusedElement}" Value="First">
<Setter Property="FocusManager.FocusedElement" Value="{Binding ElementName=txtbox1}"/>
</DataTrigger>
</Style.Triggers>
</Style>

I have a style FooStyle with some properties and an animation.
I have two other styles Bar1Style and Bar2Style which is based on the FooStyle and sets some properties. I would like to alter the the values in the animation for the Bar-styles.
In the animation I'm altering the buttons ScaleX and ScaleY values with the MouseIsOver trigger.
In the code bellow you notice the values FrameOneValue and FrameTwoValue.
<Style TargetType="Button" x:Key="FooStyle">
<Style.Resources>
<system:Double x:Key="FrameOneValue">1.0</system:Double>
<system:Double x:Key="FrameTwoValue">1.05</system:Double>
</Style.Resources>
<Setter Property="FontWeight" Value="Bold" />
<Setter Property="RenderTransformOrigin" Value="0.5 0.5" />
<Setter Property="RenderTransform">
<Setter.Value>
<TransformGroup>
<ScaleTransform/>
</TransformGroup>
</Setter.Value>
</Setter>
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimationUsingKeyFrames
Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)">
<EasingDoubleKeyFrame KeyTime="0:0:0.1" Value="{DynamicResource FrameOneValue}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="{DynamicResource FrameTwoValue}"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames
Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)">
<EasingDoubleKeyFrame KeyTime="0:0:0.1" Value="{DynamicResource FrameOneValue}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="{DynamicResource FrameTwoValue}"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimationUsingKeyFrames
Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleX)">
<EasingDoubleKeyFrame KeyTime="0:0:0.1" Value="{DynamicResource FrameTwoValue}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="{DynamicResource FrameOneValue}"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames
Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[0].(ScaleTransform.ScaleY)">
<EasingDoubleKeyFrame KeyTime="0:0:0.1" Value="{DynamicResource FrameTwoValue}"/>
<EasingDoubleKeyFrame KeyTime="0:0:0.2" Value="{DynamicResource FrameOneValue}"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>In the Bar1Style and Bar2Style styles I would like to alter the values for FrameOneValue and FrameTwoValue to suit these styles. As the XAML-code to setup for the animation is quite large I would like to have have the definition in the FooStyle.
The Bar1Style and Bar2Style might look like this:
<Style TargetType="{x:Type Button}" x:Key="Bar1Style" BasedOn="{StaticResource FooStyle}">
<Style.Resources>
<system:Double x:Key="FrameOneValue">2.0</system:Double>
<system:Double x:Key="FrameTwoValue">2.05</system:Double>
</Style.Resources>
<Setter Property="Background" Value="Blue" />
</Style>
<Style TargetType="{x:Type Button}" x:Key="Bar2Style" BasedOn="{StaticResource FooStyle}">
<Style.Resources>
<system:Double x:Key="FrameOneValue">3.0</system:Double>
<system:Double x:Key="FrameTwoValue">3.05</system:Double>
</Style.Resources>
<Setter Property="Background" Value="Red" />
</Style>I would then use this like:
<Window x:Class="Main.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Main"
mc:Ignorable="d"
Title="MainWindow" Height="450" Width="800">
<StackPanel Orientation="Vertical">
<Button Content="btn1" Style="{DynamicResource FooStyle}" />
<Button Content="btn2" Style="{DynamicResource Bar1Style}" />
<Button Content="btn2" Style="{DynamicResource Bar2Style}" />
</StackPanel>
</Window>But this fails hard due to:
Cannot freeze this Storyboard timeline tree for use across threads Which seems to be due to I have specified DynamicResource in the FooStyle.
Which means that I cannot specify values for an animation dynamically in the Bar1Style and Bar2Style styles 
Is there some way to solve this?
It's very annoying to have an entire setup of the animation for each style. I just want to alter the values in the Bar-style.

I'm working on implementing security into my application. When a user logs in a User instance is returned, and on that is a List<string> property of right, which looks like this:
List _userRights = new List
{
"can_add_employees",
"can_edit_employees",
};
The tags in the list are stored in a table. If the tag is returned, then the user has access. If it's not returned, then the user does not have acccess. The Security piece is already done.
Now, I want to implement it in XAML. Richard Deeming gave me some direction on this a while back and I've built on his idea. I now have this Behavior class: (thanks Richard)
public static class SecurityBehavior
{
private static readonly char[] TagSeparators = { '|' };
#region Allow Enable
public static readonly DependencyProperty AllowEnableProperty =
DependencyProperty.RegisterAttached("AllowEnable",
typeof(bool),
typeof(SecurityBehavior),
new PropertyMetadata(false, OnSecurityChanged));
public static bool GetAllowEnable(DependencyObject obj)
{
return (bool)obj.GetValue(AllowEnableProperty);
}
public static void SetAllowEnable(DependencyObject obj, bool value)
{
obj.SetValue(AllowEnableProperty, value);
}
#endregion
#region Security Tags
public static readonly DependencyProperty SecurityTagsProperty =
DependencyProperty.RegisterAttached("SecurityTags",
typeof(string), typeof(SecurityBehavior),
new PropertyMetadata("", OnSecurityChanged));
public static string GetSecurityTags(DependencyObject obj)
{
return (string)obj.GetValue(SecurityTagsProperty);
}
public static void SetSecurityTags(DependencyObject obj, string value)
{
obj.SetValue(SecurityTagsProperty, value);
}
private static void OnSecurityChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
bool canEnable = GetAllowEnable(sender);
if (canEnable)
{
string[] tags = GetSecurityTags(sender).Split(TagSeparators, StringSplitOptions.RemoveEmptyEntries);
foreach (string tag in tags)
{
canEnable &= SecurityService.HasRights(tag);
}
}
var element = (UIElement)sender;
element.IsEnabled = canEnable;
}
#endregion
}
Notice that it calls a static SecurityService class:
public static class SecurityService
{
private static List<string> _userRights;
public static bool HasRights(string right)
{
return _userRights.Contains(right);
}
static SecurityService()
{
_userRights = new List
{
"can_add_employees",
"can_edit_employees",
};
}
}
I then use it like this in XAML:
<TextBox Grid.Row="0"
Grid.Column="1"
Text="{Binding EmployeeName, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
local:SecurityBehavior.AllowEnable="{Binding AreFieldsEnabled, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
local:SecurityBehavior.SecurityTags="can_add_employees|can_edit_employees"/>
"AreFieldsEnabled" is a bool property on the base ViewModel that is set to true when the view is in either Add or Edit mode.
This works, there are a couple of issues I'm stuck on.
- This approach requires that I have the tags listed in the XAML. I can then add or remove tags to any specific UI element as needed, but it requires going back into the XAML to do so. I was considering setting the element's Name and have the service look it up and determine if it can be enabled.
- In some cases there are addition factors that determine if/when a UI element should be enabled, such as another checkbox beging checked, or a specific combox box item being selected somewhere else.
I'd like to hear suggestions.
Thanks

I have two style FooStyle and BarStyle.
I also have three TextBlocks and two of them use the styles above.
In the FooStyle I have specified a double (the Wid parameter) that is used to set the Width of the TextBlock (txt2) to 20.
In the BarStyle I would like to use the FooStyle but override the Wid parameter with the value 40 on the TextBlock (txt3).
But the txt3 TextBlock's Width don't get a longer Width. It still has the same Width as txt2.
Here is my code
<Window x:Class="Main.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:sys="clr-namespace:System;assembly=mscorlib">
<Window.Resources>
<Style x:Key="FooStyle" TargetType="TextBlock">
<Style.Resources>
<sys:Double x:Key="Wid">20</sys:Double>
</Style.Resources>
<Setter Property="Width" Value="{StaticResource Wid}" />
<Setter Property="FontWeight" Value="Bold" />
</Style>
<Style x:Key="BarStyle" TargetType="TextBlock" BasedOn="{StaticResource FooStyle}">
<Style.Resources>
<sys:Double x:Key="Wid">40</sys:Double>
</Style.Resources>
</Style>
</Window.Resources>
<StackPanel Orientation="Vertical">
<TextBlock Text="txt1" Background="red" Width="100" />
<TextBlock Text="txt2" Background="Lime" Style="{StaticResource FooStyle}" />
<TextBlock Text="txt3" Background="Blue" Style="{StaticResource BarStyle}" />
</StackPanel>
</Window>Is it possible to overwrite the Wid parameter in the BarStyle?
|

|

You've assigned the width using a StaticResource. If you want it to change based on the resources of the "derived" style, use DynamicResource instead.
<Setter Property="Width" Value="{DynamicResource Wid}" /> You can then override the value with the resources of a "derived" style:
<Style x:Key="BarStyle" TargetType="TextBlock" BasedOn="{StaticResource FooStyle}">
<Style.Resources>
<sys:Double x:Key="Wid">40</sys:Double>
</Style.Resources>
</Style> Or directly on the control:
<TextBox Text="txt4" Background="Purple" Style="{StaticResource FooStyle}">
<Style.Resources>
<sys:Double x:Key="Wid">80</sys:Double>
</Style.Resources>
</TextBox>

Thank you!

I have a construction management app that is used to manage house framing. The client now want to use it to manage finish work, such as doors and cabinets, etc. The structure of the data is very similar - almost identical, and functionally the app would work the same with a few one-off views for each. My thought is that when the user logs in, they would now also pick which company they want to work in.
The question is this... There are going to be some TextBlocks that will need to be changed depending on what company the user is in. For example, the word "Project" might need to say "Task" depending on the company.
One idea I'm tossing around is to store these words in a resources file, something like:
<data name="a_project_caption" xml:space="preserve">
<value>Project</value>
</data>
<data name="b_project_caption" xml:space="preserve">
<value>Task</value>
</data>
Next, in the XAML I would have something like a behavior maybe?:
<TextBlock Tag="project_caption" beh:ResolveCaption/>
The behavior takes the value in the Tag and sets the textblock's text based on what it finds in the resource file, and throws if it can't resolve it.
I'm open to suggestions on this.
Thanks!
