Hi

Please look at the photo and describe the problem to me

Code:

private void AtouAutoCompleteNameDrive()
        {
            AutoCompleteStringCollection AutoComplete = new AutoCompleteStringCollection();
            SqlDataReader SR = new Factors_C().ListNameDrive();
            if (SR.Read())
            {
                while (SR.Read())
                    AutoComplete.Add(SR["NameDrive"].ToString());
            }
            ComBoBoxNameDr.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
            ComBoBoxNameDr.AutoCompleteSource = AutoCompleteSource.CustomSource;
            ComBoBoxNameDr.AutoCompleteCustomSource = AutoComplete;
        }

Hello, Abbas,     

RadDropDownList doesn't have AutoCompleteSource property. Please refer to the following help article demonstrating how to enable and use the autocomplete functionality in RadDropDownList: https://docs.telerik.com/devtools/winforms/dropdown-listcontrol-and-checkeddropdownlist/dropdownlist/features/auto-complete

I would like to note that most of the forum threads are reviewed by Telerik representatives and sometimes we address the questions asked by our customers in the forums as well. However, a post in the forum doesn't guarantee you a response from the Telerik support team. Moreover, threads are handled according to license and time of posting, so if it is an urgent problem, we suggest you use a support ticket, which would be handled before a forum thread.

I hope this information helps. 

Regards,
Dess
