WebDropDown1.DisplayMode = Infragistics.Web.UI.ListControls.DropDownDisplayMode.ReadOnlyList
WebDropDown™ allows you to specify one of several different behavioral modes. For instance, you may want your end-users to simply select from a list of values without allowing them to type into the drop-down editor. Other times, you may want your end-users to type into the drop-down editor and try to find a list item by auto-filtering. You may even want to use WebDropDown as a read-only lookup control where the display value represents a user-friendly string that comes from a lookup table so that you do not have to present meaningless foreign key values to your end-users. These behavioral modes are a functionality of the WebDropDown control’s DisplayMode property.
The following is a list of WebDropDown display modes:
DropDownList
The end-user will be able to select an item from the value list.
