[Solved] GridViewToggleRowDetailsColumn button does not select row

[Matthias]

Hi,

I am using Silverlight 4 and the latest Telerik build.  I am having a problem with using a GridViewToggleRowDetailsColumn button with a RadGridView.  When I click the '+' sign on a row to show the RowDetails, it does not select the row at the same time.  I can expand other rows but the RowDetails only show for the selected row, which can be different from the expanded row. I have attached a screenshot to help explain.  Can anyone point me in the right direction?

Thanks,

Matt

Hi Matthias,

The purpose of the GridViewToggleRowDetailsColumn is to expand row details - it will not select the respective item. If you would like to select row details when they are expanded you could try something like this:

// subscribe to RowDetailsVisibilityChanged
private void RadGridView_RowDetailsVisibilityChanged(object sender, GridViewRowDetailsEventArgs e)
{
    if (e.Visibility.Value == System.Windows.Visibility.Visible)
    {
        e.Row.IsSelected = true;
    }
}

All the best,

That's exactly what I was looking for :)

Is there a better solution to this out now..? How is it supposed to be implemented in MVVM.

Hello,

 You can use attached behavior with the same if you want reusable MVVM style code.

A sample implementation of attached propertey (Not the beahaviour )

public static class CommandProvider

   {

       public static ICommand GetCommand(DependencyObject obj)

       {

           return (ICommand)obj.GetValue(CommandProperty);

       }

 

       public static void SetCommand(DependencyObject obj, ICommand value)

       {

           obj.SetValue(CommandProperty, value);

       }

 

      public static readonly DependencyProperty CommandProperty =

           DependencyProperty.RegisterAttached(

               "Command",

               typeof(ICommand),

               typeof(CommandProvider),

               new PropertyMetadata(

                   default(ICommand),

                   new PropertyChangedCallback(HandleCommandChangedCallback)));

 

 

   public static void HandleCommandChangedCallback(

           DependencyObject dependencyObject,

           DependencyPropertyChangedEventArgs eventArgs)

       {

         if (dependencyObject is RadGridView)

           {

               var radGrid = dependencyObject as RadGridView;

 

               if (radGrid != default(RadGridView))

               {

                   radGrid.RowDetailsVisibilityChanged += (sender, args) =>

                       {

                           if (args.Visibility.Value ==Visibility.Visible )

                           {

                               args.Row.IsSelected = true;

                           }

                       };

               }

           }

       }

   }

and in XAML :

<telerik:RadGridView extensibility:CommandProvider.Command="{Binding RowVisibilityChanged}">

RowVisibilityChanged is you RelayCommand.
