How can I get the Expanded/Collapsed Row?

[Timothy Liu]

I write these code:

 

 

 

public MainPage()

 

{

InitializeComponent();

 

 

this.gv.AddHandler(GridViewRow.IsExpandedChangedEvent, new RoutedEventHandler(this.RowExpandStatusChanged), true);

 

}

 

 

private void RowExpandStatusChanged(object sender, RoutedEventArgs e)

 

{

 

 

// My logic...

 

 

 

 

}

 

 

 

But, I got this compiler error:
------------------
Error 5 Argument 1: cannot convert from 'Telerik.Windows.RoutedEvent' to 'System.Windows.RoutedEvent'

Hello Timothy Liu,

 Use The RowLoadedEvent to achieve desired result,try this code:

private void RowExpandStatusChanged(object sender, RoutedEventArgs e)
      {

          MessageBox.Show("Hello World","");
      }


      private void HierarchicalGridView_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)
      {
          var row = e.Row as GridViewRow;
          if (row != null)
          {
              row.IsExpandedChanged+=new RoutedEventHandler(RowExpandStatusChanged);
          }

      }

Kind regards,
