Say you had a GridView with a dropdownlist like this:

asp:GridView ID="testGridView" runat="server">

Columns>

asp:BoundField DataField="TestField" />

asp:TemplateField>

ItemTemplate>

asp:ListItem Value="2">Item 2asp:ListItem>

asp:DropDownList>

ItemTemplate>

asp:TemplateField>

Columns>

asp:GridView>

testColumn.ColumnName = "TestField"

testColumn.DataType = GetType(String)
