Hi!

SO close Smile | :)

It gives a very small gap between the screen edge and the window.
I took a screenshot of the screen so that I could zoom in and check how many pixels there was between the window and the screen.

It's around 8 pixels gap on the right side.
And even if I set Left and Top to 0, I get one pixel from the top and 8 from the Left.

Here is the XML code for the window that I have now:

<Window x:Class="Sales.Menu"
        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:local="clr-namespace:Sales"
        mc:Ignorable="d"
        Top="0"
        Left="0"
        Title="Menu" Height="450" Width="{Binding Source={x:Static SystemParameters.PrimaryScreenWidth}}"
        >
    <!--The rectangle below is just a test-->
    <Grid>
        <Rectangle Width="10"></Rectangle>
    </Grid>
</Window>

I would want it go to to the edge and there to be no gaps.

Thanks for the help so far Smile | :)

Have a nice day!

Create a (dummy) maximized window in the background and copy it's properties (e.g. width) to your actual "centered" window.

I was about to try Gerry's suggestion when I decided to test retriving the screen width with code and set the window size to it.
It worked, but I wonder, is there not a way to do this without using code in WPF?
Here is the code I used if someone is interested:

this.Width = System.Windows.SystemParameters.PrimaryScreenWidth+2;

Note that +2 is there since the Windows Left parameter in the XML are set to -2, had to compensate for that or I get a small gap to the right.

I put it right below the "InitializeComponent();" call.

DataGrid with DataGridTemplateColumns - Cannot create new rows

If you want to perform mathematical functions on the bound value, you'll need a converter - for example:

I have a DataGrid with a couple of DataGridTemplateColumns.
When I try to hit the Enter-key on my keyboard there is no new row created in the DataGrid.

I have other DataGrids with columns which are not DataGridTemplateColumns and I can then create new rows by hitting the Enter-key. So I assume the DataGridTemplateColumns in some way causing the problem.

I have made a reproducible code and I have made it public in this GIT-Gist.
* I use Fody PropertyChanged to handle all the INotificationPropertyChanged in my view models.
* The code should just be copy-and-paste.

The bindings between the View and the ViewModels also don't seem to work :S
But if you uncomment the row in the ViewModel's construcotor (please see line 60 in the MainWindow.xaml.cs), a new row in the DataGrid will be created. With this row, the bindings works as expected. I cannot understand why.

Here is the XAML-code. It maybe enough for you with only the XAML-code to solve this problem.

Can't think of too many examples that use buttons and sliders in a data grid; data sources called "path" and "value"; and columns that are read-only. Worlds in collision.

The code I gave, is only an example how to reproduce the problem.
A real-life example of a button, textboxes and a slide is irrelevant.

My actual code contains of a button, a textbox, two numeric up down controls and a date picker in each row. All columns, except the textbox, are DataGridTemplateColumns.

Is there a solution to my problem?

Rather than posting all these totally vague questions, your time would be better spent actually studying the programming language(s) that you are interested in using. You will not learn it from here.

The benefit of asking "clear questions" is that you might get an "answer", instead of another "question" asking you to clarify your question. You must have a lot of time on your hands to be able to deal with just more questions (and no answers).

Helo everyone!

I have a Storyboard at Window resources as shown below.

XML

<Window.Resources>
    <!--  Storyboard as a window resource  -->
    <Storyboard
        x:Key="NB"
        x:Name="NB_resource"
        Completed="NB_resource_Completed"
        RepeatBehavior="5x">
        <ObjectAnimationUsingKeyFrames
            Storyboard.TargetName="NB_image"
            Storyboard.TargetProperty="Source"
            Duration="0:0:1.2">
            <DiscreteObjectKeyFrame KeyTime="0:0:0">
                <DiscreteObjectKeyFrame.Value>
                    <BitmapImage UriSource="pack://application:,,,/CircleSurrogateButton;component/Images/NB_00.png" />
                </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>
            <DiscreteObjectKeyFrame KeyTime="0:0:.3">
                <DiscreteObjectKeyFrame.Value>
                    <BitmapImage UriSource="pack://application:,,,/CircleSurrogateButton;component/Images/NB_01.png" />
                </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>

            <DiscreteObjectKeyFrame KeyTime="0:0:.6">
                <DiscreteObjectKeyFrame.Value>
                    <BitmapImage UriSource="pack://application:,,,/CircleSurrogateButton;component/Images/NB_02.png" />
                </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>
            <DiscreteObjectKeyFrame KeyTime="0:0:.9">
                <DiscreteObjectKeyFrame.Value>
                    <BitmapImage UriSource="pack://application:,,,/CircleSurrogateButton;component/Images/NB_03.png" />
                </DiscreteObjectKeyFrame.Value>
            </DiscreteObjectKeyFrame>
        </ObjectAnimationUsingKeyFrames>
    </Storyboard>
</Window.Resources>

The Storyboard can be started with the following string which is placed in regular Button.

XML

<EventTrigger RoutedEvent="PreviewMouseLeftButtonDown">
 <BeginStoryboard Storyboard="{DynamicResource NB}" />
 </EventTrigger>

A question is How to use a data binding in order to start that Storyboard.
For example:

XML

<DataTrigger Binding="{Binding Start_Storyboard}" Value="true">
        <DataTrigger.EnterActions>
            <BeginStoryboard Storyboard="{DynamicResource NB}"/>
        </DataTrigger.EnterActions>
 </DataTrigger>

I've tried to put DataTrigger at different places and I had got nothing besides red squiggles and exception while debugging.

Thanks in advance!
