In my project, I use a DropDownList to display the values. The value list is populated from a table. The list is over 1000 values. I can not type the part of the value and jump to the value in the list. There is also autopostback validation on the dropdownlist. I hope someone can give me some ideas how to type in part of the value to select the value in the long list without scroll down the list. Thanks, Jen
