I am getting a "bind variable does not exist" error from Oracle under the example with 1 parameter.   I even tried to assign parameter value in
srcEmployee_Updating method.     AllowAutomaticUpdates="true"

            OracleCommand cmd = (OracleCommand)e.Command;
            cmd.Parameters["location_code"].Value = "abc";

Is there a debugging mode to see what RadGrid is creating to talk to datasource for automatic updates?

    <asp:SqlDataSource ID="srcEmployee" runat="server"  ProviderName="Oracle.ManagedDataAccess.Client" DataSourceMode="DataSet"
        UpdateCommand="UPDATE mytable SET location = :location_code'">
        <UpdateParameters>
            <asp:Parameter Name="location_code" DbType="String"  Direction="Input" DefaultValue="empty" ConvertEmptyStringToNull="true" />
        </UpdateParameters>
    </asp:SqlDataSource>

                  <telerik:GridTemplateColumn HeaderText="Location Code" HeaderStyle-Width="100px" UniqueName="location_code" DataField="location_code" DataType="System.String">
                        <ItemTemplate>
                            <%# Eval("location_code") %>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadDropDownList runat="server" ID="LocationDropDown" DataValueField="location_code" DataTextField="location_code" Width="100px"
                                 DataSourceID="srcLOV">
                            </telerik:RadDropDownList>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

Through _Updating event I found out it's including this additional parameter defined in RadGrid1 DataKeyNames  (e.g.  UserID)
But UserID was not specified in UpdateCommand.

Hello,

Based on the information provided it would be hard to tell what exactly is causing the unwanted behavior. In order to determine whether the problem is related with the grid or something else in the setup I would like to ask you to replace the RadGrid with an ASP GridView and test the page again. If the issue is not reproducible then please share with us the entire page contents(markup and code-behind) so we could examine the implementation.

Regards,
