I have a Control inherited from a Listbox. The XAML looks like this:
<ListBox x:Class="Bibliothek.myDockControl" 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" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300" x:Name="myListBox" > <ListBox.ItemContainerStyle> <Style TargetType="ListBoxItem"> <Setter Property="Height" Value="{Binding ItemHeight, UpdateSourceTrigger=PropertyChanged}"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ListBoxItem"> <Border BorderThickness="1" BorderBrush="Black" CornerRadius="2"> <DockPanel> <StackPanel DockPanel.Dock="Top" Background="LightGray"> <DockPanel Margin="2,2,2,2"> <TextBlock x:Name="Beschreibung" DockPanel.Dock="Left" VerticalAlignment="Center" FontWeight="Bold" Text="{Binding Header,UpdateSourceTrigger=PropertyChanged}"></TextBlock> </DockPanel> </StackPanel> <ContentPresenter DockPanel.Dock="Top" Content="{Binding Content}"></ContentPresenter> </DockPanel> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ListBox.ItemContainerStyle> I have a binding for the Textblock and for the contentpresenter. these bindings are from my own type DockItem. Looks like this:
public class DockItem { public string Header { get; set; } public object Content { get; set; } } these property for the binding is set in the window where i tested the control and is from typ observablecollection which is binded to the itemsource of the listbox.
when i added a binding for the Height property like above(ItemHeight) that is declared in the code behind i don't know how to set the datacontext. If I set the datacontext in the codebehind of the listbox control like this: DataContext = this; then the bindings for the Header and Content doesnt work.
