Client edit with batch server update with DETAILTABLES

[Santiago Botero]

Hello Telerik Team,

So, I'm implementing the new "Client edit with batch server update" (on the DEMO) (the version i'm using is "2010.1.309.35"). The thing is I'm using a RadGrid with nested view tables (juste one by item in the master table) and the edition is taking place only on the detail tables.
So the matter is I can't get the new information two storage it on BDD because I can't get the control (neither TextBox nor RadDatePicker or whathever control be).

I try this :

the markup

<div id="divRadGridVehicles" class="MaintenanceGrid">
                <telerik:RadGrid ID="RadGrid_Vehicles" runat="server"
                    AllowPaging="True"
                    oncolumncreated="RadGrid_Vehicles_ColumnCreated"
                    onneeddatasource="RadGrid_Vehicles_NeedDataSource"
                    ondetailtabledatabind="RadGrid_Vehicles_DetailTableDataBind"
                    onitemcreated="RadGrid_Vehicles_ItemCreated"
                    onitemdatabound="RadGrid_Vehicles_ItemDataBound" >
                    <HeaderStyle Width="70px" HorizontalAlign="Center" Font-Bold="true" BorderWidth="1px" BorderColor="White"/>
                    <ItemStyle HorizontalAlign="Center" />
                    <AlternatingItemStyle HorizontalAlign="Center" />
                    <MasterTableView EditMode="InPlace"
                            CommandItemDisplay="Bottom" TableLayout="Fixed">
                            <NoRecordsTemplate>
                                <div style="height: 30px; cursor: pointer;">
                                    No items to view</div>
                            </NoRecordsTemplate>
                            <CommandItemTemplate>
                                 <div style="height: 30px; text-align: right;">
                                        <asp:Image ID="imgCancelChanges"
                                            runat="server"
                                            ImageUrl="~/App_Themes/Client/Images/Maintenance/cancel.gif"
                                            AlternateText="Cancel changes"
                                            ToolTip="Cancel changes"
                                            Height="24px"
                                            style="cursor: pointer; margin: 2px 5px 0px 0px;" onclick="CancelChanges();" />
                                        <asp:Image ID="imgProcessChanges"
                                            runat="server"
                                            ImageUrl="~/App_Themes/Client/Images/Maintenance/ok.gif"
                                            AlternateText="Process changes"
                                            ToolTip="Process changes"
                                            Height="24px"
                                            style="cursor: pointer; margin: 2px 5px 0px 0px;" onclick="ProcessChanges();" />
                                </div>
                            </CommandItemTemplate>
                        <DetailTables>
                            <telerik:GridTableView EditMode="InPlace" ClientDataKeyNames="ID, HM_ID" DataKeyNames="ID, HM_ID" >
                            </telerik:GridTableView>
                        </DetailTables>
                    </MasterTableView>
                    <ClientSettings>
                        <ClientEvents OnRowCreated="RowCreated"
                            OnRowClick="RowClick"
                            OnCommand="Grids_Command"
                            OnGridDestroying="GridDestroying"
                            OnRowDropping="onRowDropping" />
                        <Selecting AllowRowSelect="true" EnableDragToSelectRows="false" />
                        <Scrolling AllowScroll="True" />
                    </ClientSettings>
                </telerik:RadGrid>
            </div>

the server side code:

protected void radAjax_AjaxRequest(object sender, AjaxRequestEventArgs e)
    {
                //this doesn't work (return null)-------------
                //updatedItem = RadGrid_Vehicles.MasterTableView.DetailTables[Convert.ToInt32(hmId_detailTableIndex[1])].FindItemByKeyValue("HM_ID", int.Parse(hmId_detailTableIndex[0]));
                string keyValue = hmId_detailTableIndex[0];

//----------------------------------------------------
// this return the row but it is impossible to find the controls ------------

                GridTableView nestedTableView = (RadGrid_Vehicles.MasterTableView.Items[0] as GridDataItem).ChildItem.NestedTableViews[0];

               string keyValue = hmId_detailTableIndex[0];

                rowItem = nestedTableView.FindItemByKeyValue("ID", (object)int.Parse(keyValue));

                UpdateDetailVehicleValues(rowItem);
    }

protected void UpdateDetailVehicleValues(GridDataItem updatedItem)
    {
        TextBox txtBox = new TextBox();
        RadDatePicker radDatePicker = new RadDatePicker();

//It doesn't find the control

        txtBox.Text = ((TextBox)updatedItem.FindControl("txtBox_HM_ID_" + (string)updatedItem["HM_ID"].Text)).Text;
        radDatePicker.SelectedDate = ((RadDatePicker)updatedItem[""].Controls[1]).SelectedDate;

        if (updatedItem["HM_ID"].Text != "")
        {
            managerClient.managerMaintenance.UpdateHistoryMaintenance(
                Convert.ToInt32(updatedItem["HM_ID"].Text),
                txtBox.Text,
                Convert.ToDateTime(radDatePicker.SelectedDate));
        }
    }

So, how can I proceed to find the controls and get the edited information?

Best wishes,

Santiago

Hi Santiago,

Based on the supplied code, I suspect that the problem is with the way the detail table is referenced. To see more information on the matter, please refer to the following article:

http://www.telerik.com/help/aspnet-ajax/grdtraversingdetailtablesitemsingrid.html

I hope this suggestion helps.

Kind regards,

Hi Yavor,

I don't think that is the way the detail table is referenced. I can get de detail table and I can get the row which i need but without controls I added in the item_dataBound handle method. I used exactly the way to reference the detail table shown in the article:

http://www.telerik.com/help/aspnet-ajax/grdtraversingdetailtablesitemsingrid.html

So:

GridTableView nestedTableView = (RadGrid_Vehicles.MasterTableView.Items[0] as GridDataItem).ChildItem.NestedTableViews[0];

I can manage to get the information I bound initially, so the information I get from datasource, but I can't manage to get the information the user input in the textBox.

protected void UpdateDetailVehicleValues(GridDataItem updatedItem)
    {
//--------------------------------------------------------------------
//this work ----------------------------------------------------------
//-------------------------------------------------------------------
string BoundValue = updaterItem["HM_VALUE"].Text;

//----------------------------------------------------------------------------
TextBox txtBox = new TextBox();
RadDatePicker radDatePicker = new RadDatePicker();

//It doesn't find the control

        txtBox.Text = ((TextBox)updatedItem.FindControl("txtBox_HM_ID_" + (string)updatedItem["HM_ID"].Text)).Text;
        radDatePicker.SelectedDate = ((RadDatePicker)updatedItem[""].Controls[1]).SelectedDate;

        if (updatedItem["HM_ID"].Text != "")
        {
            managerClient.managerMaintenance.UpdateHistoryMaintenance(
                Convert.ToInt32(updatedItem["HM_ID"].Text),
                txtBox.Text,
                Convert.ToDateTime(radDatePicker.SelectedDate));
        }
    }

Sincerely,

Santiago

It is possible that I try to get the controls so soon in the life page cylce ???

[Santiago Botero]

I found the problem
The proble is the way the columns are bind.
The "Client edit with batch server update" works only if the columns are not autogenerated !
I managed to declare the columns in the asp mark-up and that works!!

Best regards!!
