title: ListBox items as AutoCompleteCustomSource for a textbox
body: <p>I have populated some items into a listbox using the datasource property. Now I need to set the AutoCompleteCustomSource for a textBox from the items listed in the listbox. Precisely, the DataSource for the ListBox and the AutoCompleteCustomSource for the textBox are same. How can I set the AutoCompleteCustomSource without using the for-loops?
