Binding ComboBox Item with a text property of different DataContext
- by Jhelumi786
Hi Everyone,
I have a comboBox as below. What I want is to bind the selectedItem value to a Text property of a datacontext so that another DataTemplate can show the Image. Please note that the Combobox and Target Image elements are on two different DataTemplates so that's why I need to update the Text Property (ImageName) ofDataContext at backend.
<ComboBox x:Name="cboOverlay" Grid.Row="0" Grid.Column="1" SelectedIndex="0" >
<ComboBoxItem Name="BC_OL" IsSelected="True">
<StackPanel Orientation="Horizontal">
<Image Source="Images\BC_OL.jpg" Width="100" Height="25" Canvas.Top="0" Canvas.Left="0" />
<TextBlock Width="100" VerticalAlignment="Center" TextAlignment="Center"><Bold>Image1</Bold></TextBlock>
</StackPanel>
</ComboBoxItem>
<ComboBoxItem Name="Indian_OL">
<StackPanel Orientation="Horizontal">
<Image Source="Images\Indian_OL.jpg" Width="100" Height="25" Canvas.Top="0" Canvas.Left="0" />
<TextBlock Width="100" VerticalAlignment="Center" TextAlignment="Center"><Bold>Image2</Bold></TextBlock>
</StackPanel>
</ComboBoxItem>
</ComboBox>
<Image Source="{Binding Path=Image}" Width="81" Height="25" Canvas.Top="0" Canvas.Left="0" />
