Question

I have a TextBlock in resource data template:

<DataTemplate x:Key="MyDataTemplate" ItemsSource="{Binding MySource}">
    <TextBlock x:Name="MyText" Text="{Binding ???}" />
</DataTemplate>

that I want to bind with Content of checked radio button:

<RadioButton GroupName="MyGroup" Content="Code" />
<RadioButton GroupName="MyGroup" Content="Description" />

if Code radio button is selected, then I want the text become Text={Binding Code}.

Please help, thank you.

I created 2 DataTamplate in resources, and I switch my TreeView’s ItemTemplate from code behind

if (ViewByCodeRadioButton.IsChecked == true)
    MyTreeView.ItemTemplate = Resources["MyDataTemplateCode"] as DataTemplate;
else
    MyTreeView.ItemTemplate = Resources["MyDataTemplateDesc"] as DataTemplate;
