dropdown in RadGrid

[Alex]

Hi
I have the following within a RadGrid

<telerik:GridTemplateColumn Visible="False" DataField="fk_project_id" DataType="System.Int64" FilterControlAltText="Filter fk_project_id column" HeaderText="Project" SortExpression="fk_project_id" UniqueName="fk_project_id">
                    <EditItemTemplate>
                        <telerik:RadComboBox ID="fk_project_idRadComboBox" runat="server" DataSourceID="sdsProjects" EmptyMessage="begin typing project# or name" AllowCustomText="true" Width="300px" Filter="contains"
                             DataTextField="project_full" DataValueField="id" SelectedValue='<%# Bind("fk_project_id") %>'>
                        </telerik:RadComboBox>
                    </EditItemTemplate>
                    <ItemTemplate>
                        <asp:Label ID="fk_project_idLabel" runat="server" Text='<%# Eval("fk_project_id") %>'></asp:Label>
                    </ItemTemplate>
                </telerik:GridTemplateColumn>

Im using a SqlDataSource to perform the insert but I cant seem to get the value from the radComboBox to perform the insert.
Here is the code from the Insert Parameter section
<asp:ControlParameter ControlID="fk_project_idRadComboBox" PropertyName="DataValueField" Name="fk_project_id" DbType="Int32" /> 

should I not be using a control parameter here to get at the value?           
Any help would be greatly appreciated.
Thanks
Alex

Hello Alex,

Instead of using ControlParameter, you can directly set the Name property in asp:Parameter inside InsertParameters like below.

 <InsertParameters>
              <asp:Parameter Name="fk_project_id" />
 </InsertParameters>

Thanks,
Princy.
