I have a complex radgrid and everything was working. All I want to do is add an event when the user clicks save in my edit or insert form to validate the input data on the client side and popup a radalert if there is anything wrong with the data. After introducing this to my grid:

<ClientSettings>
             <ClientEvents OnCommand="commandClicked" />
        </ClientSettings>

...
 function commandClicked(sender, eventArgs) {
        var command = eventArgs.get_commandName();
        var arg = eventArgs.get_commandArgument();
        var x = 1;
   }

then the codebehind does not work the same way it did before. I have 2 template columns which are actually grids, and in my server side code I have   updateCommand   code to go through those grids and save the data from the grids to a temporary table. The findcontrol does not find the grids i(they are null) n the templates after I add the client event handler. I does find it in my insert code, but not in my update code. I will first put just the function that is trying to find the control and then the whole code will follow.

protected void usersGrid_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        string tableName = temptablename.Text;
        string packagecd = package_cd.Text;
        //  int sbOrderDetailID = Convert.ToInt32(Session["sbOrderDetailID"]);
        int sbOrderDetailID = Convert.ToInt32(TextBoxOrderDetailID.Text);
        int nUserID = Convert.ToInt32(TextBoxUserID.Text);
        string sLoginName = TextBoxLoginName.Text;
        string sPassword = TextBoxPassword.Text;
        string sEmail = TextBoxEmail.Text;
        string sActive = TextBoxActive.Text;
        // string sPrice = Session["price"].ToString();
        double dblPrice = Convert.ToDouble(RadNumericTextBoxPrice.Value);

        GridEditableItem editedItem = e.Item as GridEditableItem;
        //      UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

        RadGrid PackageGrid = (editedItem.FindControl("PackagePriceGrid") as RadGrid);
        RadGrid alaGrid = (editedItem.FindControl("AlaCartePriceGrid") as RadGrid);

        foreach (GridDataItem item in PackageGrid.Items)
        {
            System.Web.UI.WebControls.CheckBox chkbx = (System.Web.UI.WebControls.CheckBox)item["CHECKED"].FindControl("Entitled");

            int service_id = Convert.ToInt32(PackageGrid.MasterTableView.DataKeyValues[item.ItemIndex]["service_id"]);
            Boolean oldIchecked = Convert.ToBoolean(PackageGrid.MasterTableView.DataKeyValues[item.ItemIndex]["Checked"]);

            Boolean entitled = chkbx.Checked;
            if (oldIchecked != entitled)
                Insert_update_checkbox(temptablename.Text, package_cd.Text, service_id, 0, entitled);

            item.Edit = false;
        }
        PackageGrid.Rebind();

        foreach (GridDataItem item in alaGrid.Items)
        {
            System.Web.UI.WebControls.CheckBox chkbxEntitled = (System.Web.UI.WebControls.CheckBox)item["CHECKED"].FindControl("Entitled");
            System.Web.UI.WebControls.CheckBox chkbxInvoice = (System.Web.UI.WebControls.CheckBox)item["INCLINV"].FindControl("InclInv");
            RadNumericTextBox txtboxPrice = (RadNumericTextBox)item["alaPrice"].FindControl("alaPrice");


            int service_id = Convert.ToInt32(alaGrid.MasterTableView.DataKeyValues[item.ItemIndex]["service_id"]);
            Boolean oldIchecked = Convert.ToBoolean(alaGrid.MasterTableView.DataKeyValues[item.ItemIndex]["Checked"]);
            double oldPrice = Convert.ToDouble(alaGrid.MasterTableView.DataKeyValues[item.ItemIndex]["Price"]);
            Boolean oldIncludeInvoice = Convert.ToBoolean(alaGrid.MasterTableView.DataKeyValues[item.ItemIndex]["InvoiceChecked"]);


            Boolean entitled = chkbxEntitled.Checked;
            Boolean inclInvoice = chkbxInvoice.Checked;
            double price = Convert.ToDouble(txtboxPrice.Value);

            if (oldIchecked != entitled)
                Insert_update_checkbox(temptablename.Text, TextBoxAdditionalItemsPackageCdAla.Text, service_id, 0, entitled);
            if (oldIncludeInvoice != inclInvoice)
                Insert_update_checkbox(temptablename.Text, TextBoxAdditionalItemsPackageCdAla.Text, service_id, 1, inclInvoice);
            if (oldPrice != price)
                Insert_update_price(temptablename.Text, TextBoxAdditionalItemsPackageCdAla.Text, service_id, price);
        }

        alaGrid.Rebind();
        int updated = Update_User_Calling_StoredProc(tableName, packagecd, sbOrderDetailID, nUserID, sLoginName, sPassword, sEmail, sActive, dblPrice);
        int trying = 0;
         while (updated != 0 && trying++ < 10)
           updated = Update_User_Calling_StoredProc(tableName, packagecd, sbOrderDetailID, nUserID, sLoginName, sPassword, sEmail, sActive, dblPrice);
            

        usersGrid.Rebind();
        DisplayMessage(Session["updateString"].ToString());
        CompanyInfoGrid.Rebind();

Just to add to this...it appears it cannot find any template columns in the updatecommand procedure. I have also submitted a support ticket for this as it is important I get this working.
