    i have a telerik grid with this specification

    <telerik:RadGrid ID="RadGrid1" runat="server"  GridLines="None"
              ...  DataSourceID="sqlBranchList" OnItemDeleted="RadGrid1_ItemDeleted"
               OnItemUpdated="RadGrid1_ItemUpdated" OnItemCommand="RadGrid1_ItemCommand"
                OnPreRender="RadGrid1_PreRender" Skin="Sunset">
                <MasterTableView CommandItemDisplay="TopAndBottom" DataSourceID="sqlBranchList"
                       -- Some column with Update/Insert/delete button -- 
                    <EditFormSettings EditFormType="Template">
                <EditColumn UniqueName="EditCommandColumn1"></EditColumn>
                            <table id="Table2" cellspacing="2" cellpadding="1" width="100%" border="0" rules="none"
                                style="border-collapse: collapse; background: white;">

                                                <asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true"  DataSourceID="sqlSRVUserlist" DataTextField="userName" DataValueField="userID" >
                                               <asp:ListItem Selected="True" Text="Select" Value=""></asp:ListItem>

    so i have dropdownlist in editform that fill with this datasource :

    <asp:SqlDataSource ID="sqlSRVUserlist" runat="server"
            ConnectionString="<%$ ConnectionStrings:eosWebConnectionString %>"
            SelectCommand="prcUserList" SelectCommandType="StoredProcedure">
       and i have this datasource for my grid.
        <asp:SqlDataSource ID="sqlBranchList" runat="server"
            ConnectionString="<%$ ConnectionStrings:eosWebConnectionString %>"
            SelectCommand="prcSearchBrnach" SelectCommandType="StoredProcedure"
            DeleteCommand="prcDeleteBranch" DeleteCommandType="StoredProcedure"
            InsertCommand="prcAddBranch" InsertCommandType="StoredProcedure"
            UpdateCommand="prcUpdateBranch" UpdateCommandType="StoredProcedure">
                <asp:Parameter DefaultValue="1" Name="branchStatus" Type="Int32" />
                <asp:Parameter Name="branchID" Type="Int32" />
                <asp:ControlParameter ControlID="DropDownList1" Name="userID"
                    PropertyName="SelectedValue" Type="Int32" />
                <asp:Parameter Name="branchStatusID" Type="Int32" DefaultValue="1" />
                <asp:Parameter Name="branchID" Type="Int32" />
                <asp:Parameter Name="branchName" Type="String" />
                <asp:ControlParameter  Name="userID"  ControlID="RadComboBox1"
                        PropertyName="SelectedValue" Type="Int32" />
                <asp:Parameter Name="branchStatusID" Type="Int32" DefaultValue="1" />
                <asp:Parameter Name="branchName" Type="String" />

    but when i want to update a row this error is occurred:

    Could not find control 'DropDownList1' in ControlParameter 'userID'


    i think telerik grid in edit form mode can not find controls on the page.

    please help me.

    Hello Karyjon,

    You can use Automatic DataSource operations. I am attaching a sample project demonstrating this approach. You can also review this online demo for more details.
