[Solved] RadGridView IsExpandableRecord

[Luca Mazzi]

Hi all,
I'm using RadGridView Q2 version and I need to catch the moment when a user click on a "plus" simbol on a row that has the flag

IsExpandableRecord set to true.
Does anybody know which is the event ?
If there is an event, is it fired also if the "GridViewTableDefinition" of the row is empty ?
Where can I find an example about this ?

Thanks in advance for your suggestions.

Regards

Hi Luca Mazzi,

There is no such event but you can find the toggle button of each row and subcribe to its Clicked, Unchecked, or Checked event. If you would like to be notified when an  expanded row it being closed you should subscribe to the Unchecked event. Here some sample code:

// required namespace: Telerik.Windows.Controls;
public Window1()
{
    InitializeComponent();

    this.playersGrid.RowLoaded += new System.EventHandler<RowLoadedEventArgs>(playersGrid_RowLoaded);
}

void playersGrid_RowLoaded(object sender, Telerik.Windows.Controls.GridView.RowLoadedEventArgs e)
{
    GridViewExpandableRow row = e.Row as GridViewExpandableRow;

    if(row == null)
        return;

   var expandButton = row.ChildrenOfType<ToggleButton>().FirstOrDefault();

   if (expandButton != null)
       expandButton.Unchecked += new RoutedEventHandler(expandButton_Unchecked);
}

void expandButton_Unchecked(object sender, RoutedEventArgs e)
{
    var parentRow = ((FrameworkElement)sender).ParentOfType<GridViewExpandableRow>();
}
