The DropDownList edit type column may not show any content during edit mode, although the value list has been assigned with the data source.

The problem occurred when the there is a change on Data Member property during or after the data source has been initialize. This action causes the value list that has been assigned to the data source to become expired.

If the data structure is known before runtime, the Data Member can be set within the Visual Studio Design-time.

If the data structure is not known after or at runtime, the Data Member needs to be assigned during the Page_Load event or before the WebGrid’s InitializeDataSource event.
