C#, Visual Studio 2010, dot net 4, WPF, Microsoft Ribbon
I have a WPF window with the ribbon menues at the top of the window and an area below
where I try to fill with my controls however I can not get the controls to rezise with
my window.
The listbox in the below example should be fully "expanded" witin its boundaries when the window appear and its width should follow the window width when the user resize the window
(the user should not resize the controls itself) by dragging i nthe windows sides.
I tried a lot of playing around with the controls and searched the web but have not been able to
find a solution (some site indicated the usage of border would do the trick).
The Image image1 is a background image spanning over the whole "surface".
The Image image2 is a small logo picture.

You're setting horizontal alignments to Left that shouldn't be set. Try this:
<DockPanel DockPanel.Dock="Top">
<Grid DockPanel.Dock="Top" Height="526" VerticalAlignment="Top" Margin="2" Name="BaseGrid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="1" />
<RowDefinition Height="60" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Image Grid.Column="0" Grid.Row="0" Grid.RowSpan="3" HorizontalAlignment="Left" Name="image1" VerticalAlignment="Top" Source="........./el_bg.jpg" Stretch="None" />
<Grid Grid.Column="0" Grid.Row="1" VerticalAlignment="Top" Margin="2">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="200" />
<ColumnDefinition Width="100" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="50" />
</Grid.RowDefinitions>
<Image Grid.Column="0" Grid.Row="0" HorizontalAlignment="Left" Name="image2" Stretch="Fill" VerticalAlignment="Top" Source="........./shiny_rgb.png" />
<ListBox Grid.Column="2" Grid.Row="0" Name="MessageToUser" VerticalAlignment="Top">
<ListBoxItem>One</ListBoxItem>
<ListBoxItem>Two</ListBoxItem>
</ListBox>
</Grid>
</Grid>
</DockPanel>
In addition, your ListBox is in the third column of its containing Grid. If you want it to stretch across the entire window, you will need to ensure it spans all three columns:
<ListBox Grid.ColumnSpan="3" Grid.Row="0" Name="MessageToUser"
VerticalAlignment="Top">
You should read up on WPF layout - you're setting way more properties here than you need to be. Once you understand it, you'll find this thing much more intuitive. In addition, you can use a tool like Snoop to help figure out what is wrong with your layout.
Applying the following style helped me meet this requirement:
<Style x:Key="listBoxAutoFill" TargetType="ListBoxItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListBoxItem}">
<Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"

</Border>

<Setter Property="Background" TargetName="Bd"

<Setter Property="Foreground"

</Trigger>
<MultiTrigger>
<MultiTrigger.Conditions>

<Setter Property="Foreground"
Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
My requirement is more about resizing the listbox height as the window grows/shrinks but the same can be applied for width.
<ListBox Grid.Row="1" Grid.Column="0" Width="158"
ItemContainerStyle="{StaticResource listBoxAutoFill}"
ItemsSource="{Binding ListBoxItems, Mode=TwoWay}" />

I need to bind to tag in my DataTemplate. Tried through construnction "{Binding Path=Tag, RelativeSource={RelativeSource TemplatedParent}}", but it disn't bind, shows the empty text. What am I doing wrong?
You should know that TemplateBinding can be used only in ControlTemplate, not DataTemplate. So you can try something like this as a workaround:
<TextBlock TextBlock.FontSize="12" HorizontalAlignment="Left"
VerticalAlignment="Stretch" TextAlignment="Center" Margin="6,-2,0,0"
Text="{Binding Tag,
RelativeSource={RelativeSource AncestorType=RadioButton}}"/>
I have the following ControlTemplate that I am using in an ItemsControl. It is essentially a 3x3 Grid with a Path in the center and a Textbox/Textblock on top of it. When I use this, the Path takes up all of the space within the ItemsControl, and ignores the column/row definition constraints. Can anyone tell me why this is happening? I tried wrapping the Path in a Canvas but that didn't seem to help.
Thanks!

Edit
The source for this was downloaded from hereenter link description here. If you replace the <Path Style="{StaticResource Decision}" at line 469 with the following, you will get the same result that I do.
<Path Style="{StaticResource Decision}"
ToolTip="Decision">
<s:DesignerItem.MoveThumbTemplate>
<ControlTemplate>

<TextBox MinWidth="{Binding RelativeSource={RelativeSource AncestorType=s:DesignerItem}, Path=ActualWidth}" />
</StackPanel>
<Path Grid.Column="1"
Grid.Row="1"
Style="{StaticResource Decision_DragThumb}" />
</Grid>
</ControlTemplate>
</s:DesignerItem.MoveThumbTemplate>
</Path>
The following are pictures of what I am trying to accomplish and what the actual result is. I want to display a label and a text box on all four sides of the selected item when it is selected. Ultimately the label/textbox visibility will be databound to the DesignerItem.IsSelected dependency property, but that hasn't been wired up yet.
Expected result:
Actual result:
Typically Canvas do to clip it's children by default so you need to set it explicitly as ClipToBounds="True"
eg
<Canvas Grid.Column="1"
Grid.Row="1"
ClipToBounds="True">
<Path Style="{StaticResource Square_DragThumb}" />
</Canvas>
Update
Replace the Path element in FlowChartSymbols.xaml at line 469 with the following Grid
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition />
</Grid.RowDefinitions>
<StackPanel Grid.Column="1">
<TextBlock Text="Length" HorizontalAlignment="Center"/>
<TextBox />
<StackPanel.Style>
<Style TargetType="StackPanel">
<Style.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor,AncestorType=s:DesignerItem}}"
Value="{x:Null}">
<Setter Property="Visibility" Value="Collapsed"/>
</DataTrigger>
</Style.Triggers>
</Style>
</StackPanel.Style>
</StackPanel>
<Path Style="{StaticResource Decision}"
Grid.Row="1" Grid.Column="1"
ToolTip="Decision">
<s:DesignerItem.MoveThumbTemplate>
<ControlTemplate>
<Path Style="{StaticResource Decision_DragThumb}" />
</ControlTemplate>
</s:DesignerItem.MoveThumbTemplate>
</Path>
</Grid>
this is how you can achieve the same. also fixed toolbox issue by adding a trigger to detect if it is inside a designer item or simply in a toolbox
I have a problem with my ListBox. I have written several DataTemplates which I use in a ListBox. Each one of these contains a grid and may contain a nested ListBox depending on the item.
My problem is: The height of these nested ListBoxes seem to be different to the root ListBox's height. Additionally it seems, that there is sometimes one pixel margin to the element above.
Has someone encountered this problem, too and maybe solved it?
XAML-Code:
<!-- Template for SubData-Items -->
<DataTemplate x:Key="DataTemplate">
<Grid x:Name="baseGrid" Grid.Column="0" Grid.ColumnSpan="999" Background="Violet">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="{Binding ElementName=Col0, Path=Width}" />
<ColumnDefinition Width="{Binding ElementName=Col1, Path=Width}" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="{Binding ElementName=Row0, Path=Height}"/>
</Grid.RowDefinitions>
<TextBlock Grid.Column="1" Text="{Binding Bezeichnung}" HorizontalAlignment="Left" VerticalAlignment="Center" FontSize="12" />
<Line Grid.ColumnSpan="999" Stroke="Black" X1="0" X2="{Binding ElementName=baseGrid, Path=ActualWidth, Mode=OneWay}" Y1="0" Y2="0" VerticalAlignment="Bottom" />

qqbenq gave a very nice solution . Here is another way to do it.
the control templates of ListBox and ListBoxItem has padding inside their borders. Thankfully ListBoxItem border's padding can be control by a style like so:
<Style
TargetType="ListBoxItem">
<Setter
Property="Padding"
Value="0" />
</Style>
but unfortunately for the ListBox , you will have to override the default template with all of its details to change its internal border's hard-coded padding like this:
<Style
TargetType="ListBox">
<Setter
Property="Template">
<Setter.Value>
<ControlTemplate
TargetType="{x:Type ListBox}">
<Border
x:Name="Bd"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Background="{TemplateBinding Background}"
Padding="0"
SnapsToDevicePixels="true">
<ScrollViewer
Focusable="false"
Padding="{TemplateBinding Padding}">
<ItemsPresenter
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</ScrollViewer>
</Border>
<ControlTemplate.Triggers>
<Trigger
Property="IsEnabled"
Value="false">
<Setter
Property="Background"
TargetName="Bd"
Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" />
</Trigger>
<Trigger
Property="IsGrouping"
Value="true">
<Setter
Property="ScrollViewer.CanContentScroll"
Value="false" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
One last note : remove the Margin that you added inside your xaml.
Solution complete
Add a Margin="-2,0,0,0" and a Padding="-1" to your "LBMaGruppen" named ListBox.
<ListBox x:Name="LBMaGruppen" ItemTemplate="{StaticResource DataTemplate}" ItemsSource="{Binding SubdataObjects}"
VerticalAlignment="Stretch" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" Height="Auto" Margin="-2,0,0,0" Padding="-1"
ScrollViewer.CanContentScroll="false" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Disabled" BorderThickness="0" />
Also, the "root" element's height is binded to {Binding ElementName=Gantt, Path=GridRowHeight}, while the "sub" element's height to {Binding ElementName=Row0, Path=Height}, so this must cause the difference.
It seems that you have auto height set on all your ListBox. You could try setting the height to a specific size. EDIT: I see you already have ScrollViewer settings. I think setting the height of the box to a specific size instead of auto will do what you want.
As to the padding between elements see the ListBox.ItemContainerSyle which should allow you to set the margin between elements.
I have a disabled TextBox in a Grid.
The Grid has a BackgroundColor and I want the TextBox to just show some Text.
How can I get the Background of a disabled TextBox to be Transparent?
Here is what I have tried:

If the Textbox is enabled, everything is okay and setting the Background works.
But as soon I disable it, I can no longer set the Background correctly.
Thought about some hack of Binding IsEnabled, so that the Background is set before.
-EDIT-
Strangly enough using TextBlock solves the issue. But I definitly have no style in the project that sets a background different from the default for TextBox.
I created simple window and applied style to it. Now, when I run application background is black:
In XAML it looks normal:

Because you are overriding the default template for the Window you are taking away the style effects (of which one is background = black on the root grid)
see above, i've put it in the template and it should now work (Background="White")
Below is the default template for a window (Taken From Blend)
<ControlTemplate x:Key="WindowTemplateKey" TargetType="{x:Type Window}">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
<Grid>

Based on TBohnen.jnr's answer, the actual correct answer would be do it as the default window template and add Background="{TemplateBinding Background}" to the top-level child element of the ControlTemplate. In the default template it is a Border, whereas in your case it's the Grid:
<Grid Background="{TemplateBinding Background}" Name="LayoutRoot" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
