I have a
<asp:DropDownList ID="Hello" runat="server">
<asp:BoundField HeaderText="Hello" DataField="HelloDB" />
All you have to do is tap into the
OnRowDataBind event of the
GridView. Within that, you can use
FindControl() to get the drop down, cast it as a
DropDown, then set the value.
This event is called when each row is databound, so each dropdown would be updated.
