Thank you for writing.
Currently, the RadAutoCompleteBox drop down is not exposed and there is no way to subscribe to its events in order to achieve the desired functionality. I have logged this as a feature request in our Feedback Portal
. You can track the item for status changes and add your vote for it here
To workaround this limitation you can get the popup with reflection, subscribe to its PopupOpening and PopupOpened events and change the cursor:
Your Telerik Points have been updated for this request.
var temp = radAutoCompleteBox1.TextBoxElement.GetType().GetProperty(
, System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(radAutoCompleteBox1.TextBoxElement,
RadPopupControlBase popup = temp
popup.PopupOpening += popup_PopupOpening;
popup.PopupOpened += popup_PopupOpened;
sender, EventArgs args)
Cursor.Current = Cursors.WaitCursor;
sender, CancelEventArgs args)
Cursor.Current = Cursors.Default;
Should you have any other questions do not hesitate to ask.
