WPF: Disabling a row in a GridView based off of a value in the source

[Petar]

Hi,

I found this blog post http://www.buildsucceeded.com/post/2009/07/17/WPF-Disabling-a-row-in-a-Grid-based-off-of-a-value-in-the-source.aspx that talks about using style triggers to turn the grid row on/off using binding. I cannot make this to work with my HierarchyChildTemplate control.

<telerik:RadGridView x:Name="DetailsView"
CanUserFreezeColumns="False" CanUserDeleteRows="True" CanUserInsertRows = "True"
SelectionMode="Single" SelectionUnit="FullRow"
AutoGenerateColumns="False"
ShowInsertRow="True"
ItemsSource="{Binding ReceiptEditRows, Mode=OneWay}"
SelectedItem="{Binding DataContext.SelectedRowViewModel, Mode=TwoWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}"
ShowGroupPanel="False"
IsReadOnly="False"  IsFilteringAllowed="False">
   <telerik:RadGridView.Resources>
      <Style TargetType="{x:Type telerik:GridViewRow}">
         <Setter Property="IsEnabled" Value="True" />
         <Style.Triggers>
            <DataTrigger Binding="{Binding Path=CanEditChildRow}" Value="True">
               <DataTrigger.Setters>
                  <Setter Property="IsEnabled" Value="True" />
               </DataTrigger.Setters>
            </DataTrigger>
         </Style.Triggers>
      </Style>
   </telerik:RadGridView.Resources>
   <telerik:RadGridView.Columns>

Is this supposed to work?

Hello Petar,

You may try to use a RowStyleSelector instead. Please take a look at our online documentation and demos for further reference.

Tank you for your response. There is a very little about RowStyleSelector used purely in XAML with MVVM. Do you have a sample that shows off the use with MVVM and XAML driven style selections (via binding)?

Thanks.
