It do scrolls the drop-down content, but after scrolling to the bottom position it will scroll the parent RadGridView for more mouse scrolling down.
How do i scroll the multiCombobox without affecting the parent scrollbar.
Hi Huan jia Zhou,
This behavior comes from the fact that the scroll is bubbling to the parent ScrollViewer. You can workaround this by manually handle the MouseWheel event of the RadGridView.
private void RadGridView_MouseWheel(object sender, MouseWheelEventArgs e)
e.Handled = true;
