Hi @all,
i know that there a many articles about my problem but i cant find a solution.
I am new in WPF - MVVM and i try to understand the MVVM-Logic.
So i made a little project to understand that.
For my later apps i want to load UserControls dynamicly to my Window.
In my StartView i have a Binding to the StartViewModel.
(The Binding is in the APP.xaml)
StartView app = new StartView();
StartViewModel context = new StartViewModel();
the StartView
<Window x:Class="test.Views.StartView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:views="clr-namespace:test.ViewModel"
Title="Window1" Height="300" Width="516">
<Grid>
<Menu IsMainMenu="True" Margin="0,0,404,239">
<MenuItem Header="_Einstellungen">
<MenuItem Header="Server" />
</MenuItem>
</Menu>
<ContentControl Content="{Binding LoadedControl}" Margin="0,28,0,128" />
</Grid>
</Window>
the StartViewModel
namespace test.ViewModel
{
public class StartViewModel : ViewModelBase
{
#region Fields
private UCStastistikViewModel _loadedControl;
#endregion
public StartViewModel()
{
LoadedControl = new UCStastistikViewModel();
}
#region Properties / Commands
public UCStastistikViewModel LoadedControl
{
get { return _loadedControl; }
set
{
if (value == _loadedControl)
return;
_loadedControl = value;
OnPropertyChanged("LoadedControl");
}
}
#endregion
#region Methods
#endregion
}
}
UCStatistikView
<UserControl x:Class="test.Views.UCStatistik"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:vm="clr-namespace:test.ViewModel"
mc:Ignorable="d"
d:DesignHeight="188" d:DesignWidth="508">
<UserControl.DataContext>
<vm:UCStastistikViewModel />
</UserControl.DataContext>
<Grid Background="red">
</Grid>
</UserControl>
UCStatistikViewModel
namespace test.ViewModel
{
public class UCStastistikViewModel : ViewModelBase
{
#region Fields
#endregion
public UCStastistikViewModel()
{
}
#region Properties / Commands
#endregion
#region Methods
#endregion
}
}
Now i want to load my UCStatistikView in the ContentControl of my StartView.
But in the Startview only the Path test.UCStatistikViewModel is shown instead of the whole UC
Can anybody give me some Ideas to Fix it ?

The standard way to display a usercontrol like this is to use a DataTemplate. Here's a simple data template that you could take and adapt as you need:
<DataTemplate DataType="{vm:UCStastistikViewModel}">
<view:UCStatistikView />
</DataTemplate>

I believe, it's possible, however no one want to develop payment gateway in silverlight, since it's front end and reside on client computer. if you mean to say you want to get all information regarding client details and credit card through silvelight front-end, then that possible, you can call webservice to communicate to server about this information and based on what is returned, code your logic

The program runs perfectly on my machine but when I try to execute it on an other machine, it crashes after the splash screen. I have checked the event viewer and I have copied the following stack report. I am sure that if can access the details of the inner exception to see what causes the crash I am also sure that I would be able to solve my problem. I have already lost 1 week because of this issue. Please give me an idea for solution and sorry for my poor English.

I'd guess a control or library is missing on that machine or you are trying to access some resource that is missing.
|
|
|
|
|
Thanks for reply. I thought that but the problem is how I can know which library is missing. 
|
|
|
|

Try copying all the binaries + matching .pdbs over to the other machine. You can install WinDbg which is a very small debugger from Microsoft (just a few MBs) vs. Visual Studio and debug through there.

Thank you WinDbg has helped me to figure out what is missing.

I need a binding in SolidColorBrush color value inside my theme. So basically, instead of
<SolidColorBrush x:Key="TextBrush" Color=" #FF000000" />
I want something like -
<SolidColorBrush x:Key="TextBrush" Color="{Binding ColorVal}" />
Property could be defined something like this:
namespace ns
{
public class BindingClass
{
public Color ColorVal
{
get
{
return Color.FromRgb(255, 0, 0);
}
}
}
}
Hopefully it's possible. What should I write instead of 'Binding expression' in XAML theme?
Update:
I've got one solution-
On top,
xmlns:local="clr-namespace:ns"
Then a Resource key,
<local:BindingClass x:Key="BindingClassKey"/>
Finally binding,
<SolidColorBrush x:Key="TextBrush" Color="{Binding Source={StaticResource BindingClassKey}, Path=ColorVal}" />
Any better solution?

Hi,
At present I am using an xml file to retrieve data for menu (Navigation of pages).
The xml looks like the following.
Question:
How can I make the menu to show sub menus i.e. menu within a menu?
Thanks
="1.0"="utf-8"
<Navigations>
...
<Navigation>
<item>Converter</item>
<tag>/UserControls/Converter.xaml</tag>
</Navigation>
<Navigation>
<item>Page1 view</item>
<tag>/Views/Page1.xaml</tag>
</Navigation>
<Navigation>
<item>Test Page</item>
<tag>/Views/Test.xaml</tag>
</Navigation>
...
</Navigations>
|
|
|
|

Just have menu levels in your xml file.
<Navigation>
<item>Converter</item>
<tag>/UserControls/Converter.xaml</tag>
<FirstLevel>
<item> sub level</item>
<tag>sub level</tag>
</FirstLevel>
</Navigation>
<Navigation>
<item>Page1 view</item>
<tag>/Views/Page1.xaml</tag>
</Navigation>
<Navigation>
<item>Test Page</item>
<tag>/Views/Test.xaml</tag>
</Navigation>

Yes, but how do I make it appear on the UI?
At present, I just read the item and tag of the xml file.
Does this mean that if I also read the FirstLevel element, then it will automatically show up in the UI and a sub level menu?
Thanks

It will not automatically show up.
Silverlight Menu[^] might give you an idea on what you would need to do to show a submenu.

I have a entitycollection and assigned a readonly property for each property of the entity. So that I can define whether they can be modified in Datagrid.
For example,for the same property NAME, it is allowed be be edited for some entities but others not.
But seems there is not a DataGridCell.IsReadOnly in silverlight as in WPF.
Anyone of you have met similar case ? or know that the silverlight 5 will get this supported?

Hi,
I am using a silverlight application which intern uses a wcf service which uses the controllers. We are following MVVM and Prism pattern.
While updating or retrieving the data, I am getting the following error. I have switched my VM machine from one domain to another domain and user name.
"The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Negotiate,NTLM'"
Can anybody know why I get this error and how I can resolve it. Any kind of help or link or suggestion would help me greatly.
Thanks,
Abdul

Hello!
This is my first software project using Adobe Illustrator files as interface elements. I use Microsoft Blend 4 to import those files and build my interface. The problem is simple, when I import (File -> Import Adobe Illustrator file...) and take a look at my elements, they are slightly different from the original. Mostly the colors and gradients. Can someone help me please?
