Do you want to view the text written in label as Selected Value of the dropdown??

HI farjack1,

You can assign the SelectedValue property like

<asp:TemplateField HeaderText="Test1">
                        <ItemTemplate>
                            <asp:Label ID="TestLabel" runat="server" Text='<%# Bind("ItemLabel") %>'>
                            </asp:Label>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:DropDownList ID="EditDdl" runat="server" SelectedValue='<%# Bind("BindValue") %>' >
                            </asp:DropDownList>
                        </EditItemTemplate>
                    </asp:TemplateField>

Try this

Actully i mentioned above SelectedValue property is not avaiable in

<EditItemTemplate>
                        <asp:DropDownList id="ddlProductName" runat="server"
                             DataTextField="ProductName" DataValueField="ID" DataSource='<%# loadProducts %>'
                               
                             />
                    </EditItemTemplate>
if i put that SelectedValue='<%# Bind("ProductName") %>' under dropdownlist tag then runtime error comes

System.Web.HttpException was unhandled by user code
  ErrorCode=-2147467259

if i remove  SelectedValue='<%# Bind("ProductName") %>' then works fine but value not selected as required

Hi farjack1,

U have given the wrong field to bind for the SelectedValue property...

Change it to

EditItemTemplate>
       <asp:DropDownList id="ddlProductName" runat="server"
       DataTextField="ProductName" DataValueField="ID" DataSource='<%# loadProducts %>'
       SelectedValue ='<%# Bind("ID") %>'   />
</EditItemTemplate>

Hi farjack1,

Did u try with the above said change?
