Thank you for contacting us.
The observed case is an expected behavior because the ShowDropDown
method is called right after the Focus
method. If you want to prevent this behavior, you can use the code snippet below and hide the RadDropDownList
//subscribe to the PopupOpening event of the auto complete
.radDropDownList1.DropDownListElement.AutoCompleteSuggest.DropDownList.PopupOpening += DropDownList_PopupOpening;
//close the RadDropDownList`s popup
sender, CancelEventArgs e)
As an attachment, you can find a sample demo demonstrating the suggested solution.
Hope this will help you. Let me know if you have any other questions.
