If You want to bind drop down from data base then you should remove the list items....

bring records in to datatable and bind it to dropdown list...

i think when you bind from db..the list item vl gone..bcos the dropdown list is filled with the new items from the db

ASP.NET

<asp:dropdownlist id="DropDownList3" runat="server" height="16px" width="53px" selectedvalue="<%# Bind("EdnLevel") %>" xmlns:asp="#unknown">
<asp:listitem>Nos</asp:listitem>
<asp:listitem>Kg</asp:listitem>
<asp:listitem>Ltr</asp:listitem>
 
</asp:dropdownlist>

and now you have to find the dropdownlist within grid
on rowdatabound event
eg.

dropdownlist objddl=(dropdownlist)grid1.rows[rowindex].fincontrol["dropdownlist id"];
objddl.SelectedValue="Assiged The Data What U Want"
