AutoCompleteModes

The AutoCompleteMode property controls auto-complete behavior and can be set to None, Suggest, Append and SuggestAppend.

You can set the AutoCompleteMode as follows:

Set AutoCompleteMode

this.radCheckedDropDownList1.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

Me.RadCheckedDropDownList1.AutoCompleteMode = AutoCompleteMode.SuggestAppend

• None: Nothing happens when a user begins to type into the text box portion of the control.

• Suggest: As the user types an entry into the text box, the drop-down portion of the control is shown, and the items that contains the entered text are displayed.

• Append: As the user types, the next item in the list that matches the user input is automatically appended to the characters the user has already typed. The drop-down list is not shown without the user clicking the arrow.

• SuggestAppend: Similar to the Append setting, but the drop-down list is shown and the suggested item is highlighted.
