This is one of the solutions to fit the lengthy items of the dropdownlist:

By using ajaxToolkit: PopupControlExtender control.

Place the Dropdownlist in the popupcontrolextender like:
<ajaxToolkit:PopupControlExtender ID="<Control Name>" TargetControlID="<Target Control Id>" PopupControlID="<DropDownlist Id>" runat="server" />

Place a textbox and a dropdownlist. By setting the Target control as: Textbox, the user can see the textbox and on focus of the textbox the Dropdownlist will be popped up. Select a value from the dropdownlist and assign to the textbox.

Don’t specify the width for the dropdownlist, since the list should extended according to the length of the Listitems.

I the selectedindexchanged event of the dropdownlist call the function of ajaxcontrol as:

popupcontrolextender1.commit (dropdownlist1.selecteditem.text);

By doing so, the text of selected dropdownlist will be assigned as a textbox value and the popupcontrol gets hidden.
