Below is my code:
public static void ImageDoubleClick(FileModel file)
{
if (file == null)
{
return;
}
Process.Start(new ProcessStartInfo(file.FileName)
{
UseShellExecute = true
});
}
When I double click the image it supposes to open the file with system shell. But when I double click. nothing happened as if I didn't trigger the event. But I knew it did.
So I added a breakpoint at "Process.Start" line. It did stop. Then if I click "Continue", the file will be opened properly.
What am I missing here? Thanks for your help.
the Code for the xaml is:
<ContentControl VerticalAlignment="Center"
cal:Message.Attach="[Event MouseDoubleClick]=[Action ImageDoubleClick($dataContext)]">
<StackPanel x:Name="border"
VerticalAlignment="Center"
cal:Message.Attach="[Event MouseLeftButtonUp]=[Action ImageClick($dataContext)]"
Orientation="Horizontal">
<Border Height="25" Width="25">
<StackPanel>
<Canvas Width="24" Height="24"
HorizontalAlignment="Center"
VerticalAlignment="Center"
>
<Canvas.Background>
<ImageBrush ImageSource="{Binding FileImage}"
AlignmentX="Center"
AlignmentY="Center"
Stretch="Fill" />
</Canvas.Background>
<CheckBox Name="myCheckBox"
IsChecked="{Binding IsSelected}"
Visibility="Collapsed" />
</Canvas>
</StackPanel>
</Border>
<StackPanel HorizontalAlignment="Left"
VerticalAlignment="Center"
Visibility="{Binding ImageTextEnabled, Converter={StaticResource VisibleIfTrueConverter}}"
>
<TextBlock Text="{Binding DisplayName}"
FontFamily="Microsoft YaHei, Arial"
FontSize="7"
FontWeight="Bold"
Foreground="Black"
Style="{StaticResource MaterialDesignOverlineTextBlock}"
TextWrapping="NoWrap"
HorizontalAlignment="Left" VerticalAlignment="Center"
Margin="5,0,0,0"
Width="200" />
<TextBlock Text="{Binding CreatedDateTime, Mode=OneWay, StringFormat='yyyy-MM-dd HH:mm:ss'}"
FontFamily="Microsoft YaHei, Arial"
FontSize="7"

Foreground="Gray"

TextWrapping="NoWrap"
HorizontalAlignment="Left" VerticalAlignment="Center"
Margin="5,0,0,0"
Width="200" />
</StackPanel>
</StackPanel>
</ContentControl>
And I just tried and figured out this code works just fine after compiling. It is only working weird in visual studio 2019 debugging mode. No clue what's wrong.
(Not answer but alternative)
System.Diagnostics.Process.Start(file.FileName);

I'm using the Material Design in a WPF XAML application, I've got this section of code bellow, when the grid is outside of a "materialDesign:Flipper" it all renders correctly; ie- it grows/stretch's correctly with the size of the window and it stacks nicely inside of the StackPanel.
However, as soon as I place this code inside of a Flipper, the scaling and positioning becomes skewed. If I start to change the size of the window it will resize funnily and will not stack nicely. Please see both the image and video bellow for more info. Thank you.
Please note all this code is contained within side a "StackPanel", the intention is such that they can be copied and pasted multiple times.
Working Code outside a Flipper:
<Grid Height="89">
<Grid Width="77" HorizontalAlignment="Left" VerticalAlignment="Center" Margin="7,3,0,2" Panel.ZIndex="2" Height="84">
<Ellipse Fill="{Binding Colour}" HorizontalAlignment="Left" Height="77" StrokeThickness="3" Stroke="#FF464646" Width="77" Effect="{DynamicResource MaterialDesignShadowDepth2}" />
<TextBlock Text="{Binding Name}" VerticalAlignment="Center" HorizontalAlignment="Center" TextAlignment="Center" Width="90" FontSize="{Binding FontSize}" Foreground="White" />
</Grid>
<UniformGrid Rows="2" Columns="1" Panel.ZIndex="3" Margin="89,18,72,0">
<TextBox TextWrapping="Wrap" Text="{Binding BrandName}" FontSize="24" Grid.ColumnSpan="1"/>
<Label Content="Brand Name" Grid.ColumnSpan="1" Grid.RowSpan="2" Margin="-2,-3,2,3"/>
</UniformGrid>
<Button Style="{StaticResource MaterialDesignFloatingActionMiniDarkButton}" HorizontalAlignment="Right" Panel.ZIndex="4" Content="{materialDesign:PackIcon DotsHorizontal}" Command="{x:Static materialDesign:Flipper.FlipCommand}" Margin="0,25,19,24"/>
<materialDesign:Card Margin="24,0,5,5" VerticalAlignment="Bottom" Height="72" Panel.ZIndex="-1" />
</Grid>
Broken Code, inside a Flipper:
<materialDesign:Flipper Visibility="{Binding IsVisible}" Background="#FFE89595" HorizontalAlignment="Stretch">
<materialDesign:Flipper.FrontContent>

Thank you for any help.
I have a WPF application with one window. In that window I have several StackPanels and several Buttons. White can find each Button perfectly, but with exact the same code just one single Button is seldom found and often not found. I was unable to find out what the cause is for this behaviour. Thats why I came to you guys.
Note: Before the buttons are shown, there is another view (in the same window) that waits for the server to respond. As soon as the response is in, the buttons get displayed.
Here my testcode:
[TestMethod]
public void ClickBarPayment_ViewExchanges()
{
DelayedStart(5);
Application app = null;
try
{
app = Application.Launch(SutPath);
try
{
var window = app.GetWindow("CfeMain");
var button = (Button)window.Get(SearchCriteria.ByAutomationId("CashButton"), TimeSpan.FromSeconds(60));
button.Click();
Assert.AreEqual(false, button.Visible);
}
catch (Exception e)
{
Assert.Fail(e.Message);
}
}
finally
{
app?.Close();
}
}
You can assume, that the Buttons are all equal and all have a Tag " Name="" ". Here is the XAML code, I remove unnecessary names with "Blabla" a.s.o.
<StackPanel Name="PaymentContent" Visibility="Visible" VerticalAlignment="Center" Margin="0,0,0,0">

Without actually facing the issue I can make only suggestions.
Potential reason could be that window object getting initialized prior to having all buttons enabled in actual Application window.
You could add a wait time prior to initialize window
I'm getting such error
The name 'ScoreBtn' does not exist in the current context
and
The name 'LvlBttn' does not exist in the current context
on c# side but I can get text of Label x:Name="Lines". Where is mistake and how can I fix it?
Thanks for any help,

This will get you the Label for the button named Score. "ScoreBtn"is the name of the label element. It's not as complicated as I thought it would be.
var label = (Label)Score.Template.FindName("ScoreBtn", Score);
You really ought to listen to Peter Duniho, write a viewmodel, and bind the label's Content property to a viewmodel property, but if you don't already have a viewmodel, you may not want to rewrite your entire project. Since you don't have a single Binding in your XAML, I imagine that might be the case.
I have a Binding page for some bugs and another one for comments in my app. The first one work properly, but the second one don't show anything but the data(21 comments) load successfully.
I've been taking a look to the live Live Property Explorer and the first Grid have those options:
However, the second one have the ItemsSource set as null:
This should not be possible, because those items have the same code just with few changes to make them load different.
Here you have the code:
<Page.Resources>
<DataTemplate x:DataType="data:Book" x:Key="BookDataTemplate">
<StackPanel HorizontalAlignment="Center">
<Image Width="150" Height="150" Source="{x:Bind CoverImage}" />
<StackPanel HorizontalAlignment="center" Orientation="Horizontal">
<TextBlock FontSize="10" Text="{x:Bind DScore}" HorizontalAlignment="Center" Foreground="#FF21C721" />

</StackPanel>
<TextBlock FontSize="16" Text="{x:Bind Title}" HorizontalAlignment="Center" Foreground="White" />
<TextBlock FontSize="10" Text="{x:Bind Author}" HorizontalAlignment="Center" Foreground="#FF9C9C9C" />
<ToolTipService.ToolTip>
<TextBlock Text="{x:Bind DData}"/>
</ToolTipService.ToolTip>
</StackPanel>
</DataTemplate>
</Page.Resources>
<GridView ItemsSource="{x:Bind Books}" AllowDrop="True" IsSwipeEnabled="True" IsItemClickEnabled="True" ItemClick="Content_ItemClick" Name="Content" Margin="0,100,0,40" CanReorderItems="True"
CanDragItems="True"
ItemTemplate="{StaticResource BookDataTemplate}" ReorderMode="Enabled"/>
And the Comments gridview:
<Page.Resources>
<DataTemplate x:DataType="data:Comment" x:Key="CommentDataTemplate">
<StackPanel HorizontalAlignment="Center">
<Grid>
<Rectangle Margin="50, 0, 0, 30" Fill="#FF144772" Height="100" Stroke="Black" Width="500" HorizontalAlignment="Center"/>

CanDragItems="True"
ItemTemplate="{StaticResource CommentDataTemplate}" ReorderMode="Enabled"/>
Can somebody help me identify the problem here please?
In the XAML file of your 2nd page go to "Comments" in ItemsSource and press F12. If you could navigate to definition of Comments means your binding is successful but Comments is not getting populated. If you could not navigate to definition means binding is not working. In that case check if datacontext has been set for that page. Also check how "Comments" is spelled in XAML and in the property.
The items below show up normally when I do not have them inside the HyperlinkButton.
However, when I add them to the HyperlinkButton, they become invisible.
<DataTemplate>
<HyperlinkButton NavigateUri="/ViewChallenge.aspx">
<HyperlinkButton.Content>
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<Image Height="100" Width="100" Source="{Binding Path=Challenge.Image}" Margin="12,0,9,0"/>
<StackPanel Width="311">
<TextBlock Text="{Binding Path=Challenge.Title}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
<HyperlinkButton NavigateUri="ViewUser.aspx" >
<HyperlinkButton.Content>
<TextBlock Text="{Binding Path=User.Username}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
</HyperlinkButton.Content>
</HyperlinkButton>
</StackPanel>
</StackPanel>
</HyperlinkButton.Content>
</HyperlinkButton>
</DataTemplate>
As far as I know, the Hyperlink button only supports text. For example:
<HyperlinkButton Height="100" Width="300">
Hello World
</HyperlinkButton>
Maybe you should use a Button control and set a Control template and enter the XAML you mentioned above inside. It makes more sense in my opinion. Try this:
<ControlTemplate x:Key="MyButtonTemplate" TargetType="Button">
<StackPanel Orientation="Horizontal" Margin="0,0,0,17">
<Image Height="100" Width="100" Source="{Binding Path=Challenge.Image}" Margin="12,0,9,0"/>
<StackPanel Width="311">
<TextBlock Text="{Binding Path=Challenge.Title}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
<TextBlock Text="{Binding Path=User.Username}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
</StackPanel>
</StackPanel>
</ControlTemplate>
And simply set the template for your button like so:
<Button x:Name="myButton" Template="{StaticResource MyButtonTemplate}" Click="myButton_Click"/>
And then do the navigation inside the click event.
