The scenario you describe (custom popup) has nothing to do with event tunneling or bubbling. Whatever is getting "passed", it's not an "event".

What is a "layer"? One can't confuse the logical and the physical when trying to solve a problem.

DataGrid Column Right Aligned

Here's my code:

<DataGridTextColumn Header="PO Cost" 
                    Binding="{Binding Total, StringFormat=C, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                    Width="100"
                    IsReadOnly="True">

<pre>
<DataGridTextColumn.HeaderStyle>
    <Style TargetType="DataGridColumnHeader">
        <Setter Property="HorizontalContentAlignment" Value="Right" />
    </Style>
</DataGridTextColumn.HeaderStyle>

<DataGridTextColumn.ElementStyle>
    <Style TargetType="{x:Type TextBlock}">
        <Setter Property="HorizontalAlignment" Value="Right" />
    </Style>
</DataGridTextColumn.ElementStyle>

The problem is that the header style changes the way the header looks. Here is a screen shot: https://1drv.ms/u/s!AjBmoYAYz_v2ghvO9qNjDcOFvZGh?e=feNnPO

Any ideas what's wrong?

Just spent 10 minutes trying to get the syntax for HeaderTextAlignment before I realised I used Telerik grids for that.

In the past I have created the header style for ALL columns and then based the right align on that custom header. Ghu knows what they have done to the built in style.

Looks like you've got a custom header style defined somewhere, which is not being picked up as the base style for your right-aligned style.

If you can find the custom header style, you might be able to use BasedOn to fix the right-aligned style:

WPF C# Make window's the same width as the screen

Hi!

I am trying to make a window that when it starts, takes up the entire width of the screen, regardless of resolution.

I have tried to set the Width to 100% and to bind it to the primary screen width

Width="{Binding SystemParameters.PrimaryScreenWidth}">

But neither worked Frown | :(

Anyone have any idea on how to do it?

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 | :)

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

Mc_Topaz7-Oct-19 23:42

7-Oct-19 23:42

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?

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).

How to use DataTrigger to run Storyboard?

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!
