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

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!!
