Hide GridViewToggleRowDetailsButton depending on ViewModel property

[Matthias]

Hi!

I am trying to hide the GridViewToggleRowDetailsButton depending on a property ("HasDetails") in the Viewmodel.
When the button is clicked I want to dynamically load the data for the rowdetails from a database.

In wpf I can achive this by using the folllowing Columndefinition:

<telerik:GridViewToggleRowDetailsColumn x:Uid="telerik:GridViewToggleRowDetailsColumn_1"  IsReorderable="False" IsResizable="False">
    <telerik:GridViewToggleRowDetailsColumn.ToggleButtonStyle>
        <Style x:Uid="Style_2" TargetType="telerik:GridViewToggleButton">
            <Setter x:Uid="Setter_4" Property="Visibility" Value="{Binding Path=HasDetails,Converter={StaticResource BoolToVisibilityConverter}}" />
            <Setter x:Uid="Setter_5" Property="Command" Value="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadGridView}}, Path=DataContext.ShowProtocolsCommand}"/>
             <Setter x:Uid="Setter_6" Property="CommandParameter" Value="{Binding }"/>
        </Style>
    </telerik:GridViewToggleRowDetailsColumn.ToggleButtonStyle>
</telerik:GridViewToggleRowDetailsColumn>

How can I do the same in Silverlight?

Best Regards,
Matthias

Hello Matthias,

Silverlight 4 internally does not support bindings in styles, so this approach won't work in silverlight due to this framewrok limitation. However, I have prepared an example project that illustrates how to retemplate GridViewDataColumn, in order to achieve GridViewToggleRowDetailsColumn's functionality.
