I am having a TabControl and within it a TabItem having a ContentControl. This ContentControl is applied a datatemplate. The code is here:
<TabControl x:Name="tabControl1" Tag="Giving URI here works">
<TabItem x:Name="tabItem1" Tag="Giving URI here doesnt work">
<ContentControl ContentTemplate="{StaticResource myOptionsDataTemplate}">
<StackPanel>
<TextBlock Text="Some Text" />
</StackPanel>
</ContentControl>
</TabItem>
</TabControl>
And the data template is:
<DataTemplate x:Key="myOptionsDataTemplate">
<Border>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<DockPanel LastChildFill="True">
<Image Source="{Binding Path=Tag, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type TabItem}}}"
Width="32" Height="32"
HorizontalAlignment="Left"
VerticalAlignment="Top"
DockPanel.Dock="Left"
Margin="0,0,4,0"/>
<Label Content="Some Text"
/>
</DockPanel>
<ContentControl Grid.Row="2" Content="{TemplateBinding ContentControl.Content}"/>
</Grid>
</Border>
</DataTemplate>
Notice the Image Source in the datatemplate is Tag of TabItem. This isn't working. But if I change the Source to take the Tag of TabControl it works.
Any reason why using Tag of TabItem is not working??
