Cancellation Of The Change Expanded

[Alexandr]

Good day.
I need to catch changes Expanded and under certain conditions, to cancel this action.
I tried to implement this by using event GroupRowIsExpandedChanging, but property args.Row.IsExpanded has changed.
Help me, please :(

Hello,

You can still use this event to cancel the expanded case. Just keep in mind the value of the e.Row.IsExpanded is the value after the user's action, not before it.

For example:

private void clubsGrid_GroupRowIsExpandedChanging(object sender, Telerik.Windows.Controls.GridView.GroupRowCancelEventArgs e)
{
    if (DoNotExpandFlag)
    {
        if (e.Row.IsExpanded)
        {
            e.Cancel = true;
        }
    }
}

Regards,
