I`ve created big button which contains grid as below:
<Button Height="Auto" Width="Auto" Command="{Binding ContinueWithoutScan}" BorderThickness="0">
<Button.Template>
<ControlTemplate>
<Grid >
<TextBlock HorizontalAlignment="Center"
TextWrapping="Wrap" Text="Text"
VerticalAlignment="Center" FontWeight="DemiBold"
Height="Auto" Width="Auto"
FontSize="25" Foreground="White"/>
<materialDesign:PackIcon Height="Auto" Width="70" Kind="ChevronRight" Foreground="White"
VerticalAlignment="Center" HorizontalAlignment="Right"/>
</Grid>
</ControlTemplate>
</Button.Template>
</Button>
There is problem that only TextBlock inside Template is clickable. Does anyone know how do I make whole content clickable? I working with MVVM so I dont want make Grid.OnMouseEneter.
Is there option to do that of I have to use EventTriggers?
The Grid needs to have a Background other than the default null to receive input events. You may set a transparent background instead of null:
<Grid Background="Transparent">
...
</Grid>

I have a program that lets you edit different properties so that you can edit a different control.
I'm trying to get the layout right for the editor but I can't seem to get it easily.
I have put it in a viewbox so it sizes according to the screen. This is the XAML for the editor:
<Viewbox Grid.Column="0" Grid.Row="2" VerticalAlignment="Top" HorizontalAlignment="Center">
<TabControl Background="{DynamicResource CustomOrange}">
<TabItem Header="Background" Visibility="Visible" FontSize="10">
<StackPanel>
<DockPanel LastChildFill="False">
<Label Content="Background" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="30"/>
</DockPanel>
<DockPanel LastChildFill="False" Margin="2">
<Label Content="Background Image" DockPanel.Dock="Left"/>
<Button Content="Find Image" DockPanel.Dock="Right"/>
</DockPanel>
<DockPanel LastChildFill="False" Margin="2">
<Label Content="Show Text" DockPanel.Dock="Left"/>
<CheckBox Content="Find Image" DockPanel.Dock="Right" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</DockPanel>
</StackPanel>
</TabItem>
<TabItem Header="Button" Visibility="Visible">
<StackPanel>
<DockPanel LastChildFill="False">
<Label Content="Background IMAGE" HorizontalAlignment="Center" VerticalAlignment="Center" FontSize="30"/>
</DockPanel>
<DockPanel LastChildFill="False" Margin="2">
<Label Content="Background Image" DockPanel.Dock="Left"/>
<Button Content="Find Image" DockPanel.Dock="Right"/>
</DockPanel>
<DockPanel LastChildFill="False" Margin="2">
<Label Content="Show Text" DockPanel.Dock="Left"/>
<CheckBox Content="Find Image" DockPanel.Dock="Right" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</DockPanel>
</StackPanel>
</TabItem>
</TabControl>
</Viewbox>
The problem is that the first TabItem looks like this:
But because I have changed the content of the label, the second TabItem looks like this:
Now, I know there are simpler ways to do this, but the problem is I don't know for sure how many options I am implementing for the user (Width, Height, Location, Font, Background, Content etc).
I have done it before with a grid but the problem is anytime I remove an option then all of them need to be re-done so that they are all in the exact Grid.Row which is why I am using StackPanel for the rows, and I am using the DockPanel so they keep separated horizontally
Thank you!!!
Below is the code scenario.
<controls:TabControl x:Name="TC" Background="Black" Grid.Column="0" Grid.ColumnSpan="2" Margin="0,0,0,8" Style="{StaticResource TabControlStyle1}" HorizontalAlignment="Left" VerticalAlignment="Center" HorizontalContentAlignment="Left" VerticalContentAlignment="Center" Padding="2">
<controls:TabItem Header="TAB1" x:Name="Tab1" Style="{StaticResource TabItemStyle2}" Foreground="#FFFDFDFD">
<Grid>
<local:UC1 x:Name="childUc1" Width="Auto" Height="Auto"/>
</Grid>
</controls:TabItem>
<controls:TabItem Header="TAB2" x:Name="Tab2" Style="{StaticResource TabItemStyle2}" Foreground="White">
<Grid>
<local:UC2 Margin="0" Width="Auto" HorizontalContentAlignment="Left" HorizontalAlignment="Left" VerticalAlignment="Center"/>
</Grid>
</controls:TabItem>
</controls:TabControl>
Here from the second tab there is one control and from that control there is one button when user click on that button then that would change to first tab. How this possible?
Please anybody help on this issue then that would be a good.
Thanks,
I assume you are always going to have two tabs,On the click event of usercontrol, you can do like this,
TC.SelectedIndex = 0;
I'm very new to Silverlight and trying to create a Button with a nested TextBlock, while having both live inside a Grid. Everything works fine except only the text is clickable...
<Grid x:Name="ValueHeadingContainer" Grid.Column="0" Grid.Row="0" Grid.RowSpan="2">
<Border Background="Transparent" BorderThickness="0,0,1,1" BorderBrush="#000" />
<Button Click="Button_Click" Name="ValueHeadingButton">
<Button.Template>
<ControlTemplate>
<TextBlock x:Name="ValueHeadingLabel"
Text="{Binding ValueLabel}"
Margin="10,0,0,0"
Style="{StaticResource FakeColumnHeader}"/>
</ControlTemplate>
</Button.Template>
</Button>
</Grid>
Only the textblock is clickable because you have not defined any other elements that will handle a mouse event. You need to put a wrapper around the textblock to increase the clickable surface area of your button.
I also suggest you set IsHitTestVisible on your TextBlock to false to prevent it interfering with any other mouse events.
<Button.Template>
<ControlTemplate>
<Border Background="Transparent">
<TextBlock x:Name="ValueHeadingLabel"
IsHitTestVisible="False"
Text="{Binding ValueLabel}"
Margin="10,0,0,0"
Style="{StaticResource FakeColumnHeader}"/>
</Border>
</ControlTemplate>
</Button.Template>
If all you want is a single button (not template), then it is sufficient:
<Button Click="Button_Click" Name="ValueHeadingButton">
<TextBlock x:Name="ValueHeadingLabel"
Text="{Binding ValueLabel}"
Margin="10,0,0,0"
Style="{StaticResource FakeColumnHeader}"/>
</Button>
I.e. you just use smth like <Button><TextBlock></TextBlock></Button> without content templates.
I have created a modal WPF window that looks as follows:
Here is the code for the window:
<Window x:Class="Dionysus.Core.Controls.ModalWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="ModalWindow" AllowsTransparency="True" Background="Transparent" WindowStyle="None">
<Grid Name="MainGrid">
<Rectangle Fill="Gray" Opacity="0.7" />
</Grid>
The "ErrorControl" is then added as follows:
MainGrid.Children.Add(uc);
The problem is as soon as I expand the stack trace, the controls transparency also changes:
I am assuming this has something to do with the ScrollViewer that uses the incorrect transparency, ie of the Rectangle instead of the containing Window.
I have also set the Opacity of the UserControl which owns the ScrollViewer to 1 and then binded the Opacity:
<ScrollViewer Background="WhiteSmoke" Opacity="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=UserControl}, Path=Opacity}">
Can anyone help me?

UPDATE
Here is the code for the UserControl that is inserted into the Window
<Grid x:Name="LayoutRootx" Background="WhiteSmoke">
<StackPanel VerticalAlignment="Stretch">
<TextBlock TextWrapping="Wrap" Margin="5" Text="An error has occured:" Foreground="Black" FontSize="15" FontWeight="Medium"/>
<TextBlock TextWrapping="Wrap" Margin="5,10,5,5" Text="{Binding Error}"/>
<odc:OdcExpander Header="Stack Trace" Margin="5" IsExpanded="False" Background="WhiteSmoke">
<TextBox Text="{Binding StackTrace}" TextWrapping="Wrap" Margin="5,10,5,5" IsReadOnly="True" MaxHeight="370"/>
</odc:OdcExpander>
<odc:OdcExpander Header="Comment" Margin="5" IsExpanded="False">
<TextBox Text="{Binding Comment}" TextWrapping="Wrap" Margin="5,10,5,5" MaxHeight="370" Name="txtComment"/>
</odc:OdcExpander>
<StackPanel Margin="5,10,5,5" Orientation="Horizontal" HorizontalAlignment="Left">
<Button Style="{StaticResource DionysusButton}" Width="100" Height="23" IsDefault="True" Name="btnSendError">
<StackPanel Orientation="Horizontal">
<Image Source="/Dionysus.Shell;component/Images/camera-icon.png" Margin="0,0,5,0">
</Image>
<TextBlock Text="Send to IT" VerticalAlignment="Center"/>
<core:DionysusTriggerAction Height="0" Width="0" TargetControl="{Binding ElementName=btnSendError}" MethodName="SendError"></core:DionysusTriggerAction>
</StackPanel>
</Button>
<Button Style="{StaticResource DionysusButton}" Width="100" Height="23" Name="btnExit" Margin="10,0,0,0" IsCancel="True">
<StackPanel Orientation="Horizontal">
<Image Source="/Dionysus.Shell;component/Images/DeleteRed.png" Margin="0,0,5,0">
</Image>
<TextBlock Text="Close" VerticalAlignment="Center"/>
</StackPanel>
</Button>
<core:DionysusTriggerAction Height="0" Name="triggerAction2" Width="0" TargetControl="{Binding ElementName=btnExit}" MethodName="Exit"></core:DionysusTriggerAction>
</StackPanel>
</StackPanel>
</Grid>
If your window has a fixed size and cannot be resized, you can use the following trick:
<Grid>
<Border BorderThickness="100" BorderBrush="Gray" Opacity="0.7">
<Grid Background="White" Grid.Column="1" Grid.Row="1" x:Name="contentPlaceHolder">
<TextBlock Text="HELLO WORLD" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Border>
</Grid>
However, it is unlikely that your Window will always have the same size, so to make it more dynamic, you could change the layout of the Window as follows:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="YourDesiredSize"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="YourDesiredSize"/>
<RowDefinition/>
</Grid.RowDefinitions>
<Rectangle Fill="Gray" Opacity="0.7" Grid.Row="0" Grid.ColumnSpan="3"/>
<Rectangle Fill="Gray" Opacity="0.7" Grid.Row="2" Grid.ColumnSpan="3"/>
<Rectangle Fill="Gray" Opacity="0.7" Grid.Row="1" Grid.Column="0"/>
<Rectangle Fill="Gray" Opacity="0.7" Grid.Row="1" Grid.Column="2"/>
<Grid Grid.Column="1" Grid.Row="1" Background="White" x:Name="contentPlaceHolder">
<TextBlock Text="HELLO WORLD" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
</Grid>
The result of this window placed on top of another looks more or less like this:
and then instead of adding to the MainGrid, add the UserControl to the contentPlaceHolder or however you want to call it:
contentPlaceHolder.Children.Add(uc);
Okay so I found a solution that works for me, I'm sure it's not the best but it might help someone having the same problem as I did.
The problem was that controls within my UserControl that I added to my Window were transparent, although I could not figure out the reason, I found a simple workaround.
By changing the OpacityMask property of the UserControl to whatever the required Background colour is, even if the controls opacity changes, it will be masked with the Brush that you supply.
uc.OpacityMask = Brushes.WhiteSmoke;
Hope it helps someone!
I have a dock panel, with one label in the middle and another button on the far right.
Because of the button the label cannot align to the middle when the windows is maximized.
WPF:
<DockPanel Height="40" HorizontalAlignment="Stretch" Margin="-1,-2,0,0" Name="dockPanel1" VerticalAlignment="Stretch" Width="Auto" OpacityMask="{x:Null}">
<Label FontSize="18" Content="Sales" FontWeight="Bold" FontFamily="Arial" Width="883" Height="42" HorizontalAlignment="Center" HorizontalContentAlignment="Center" Foreground="White" DockPanel.Dock="Left" VerticalAlignment="Center" VerticalContentAlignment="Center"></Label>
<Button FontSize="18" Height="47" Width="123" Name="btnStart" Foreground="White" BorderBrush="{x:Null}" FlowDirection="LeftToRight" HorizontalContentAlignment="Center" FontFamily="Arial Rounded MT" ClickMode="Press" DockPanel.Dock="Right" HorizontalAlignment="Right" VerticalAlignment="Center" Padding="0" Content="Start" BorderThickness="0" Focusable="False">
</DockPanel>
Use a Grid instead of a DockPanel
Grid's allow objects to be placed on top of each other, so you can position your Label in the middle and the Button on the Right
<Grid>
<Label HorizontalAlignment="Center" VerticalAlignment="Center" />
<Button HorizontalAlignment="Right" />
</Grid>
Also if you're new to WPF's Layouts, I'd recommend reading through WPF Layouts: A Quick Visual Start so you know what layouts are available and can pick the best one for your sitaution
