Hello Cesar,


In order to get reference to the RadTextBox in the EditItemTemplate you can use the OnBatchEditOpened event. The handler would look similar to the following:

I want to access both Literal in ItemTemplate and Textbox in EditItemTemplate in this event. Is this possible?

My scenario is, I want to set hidden input(placed in Item Template) value on BatchEditCosed Event. I will get value from Dropdown in EditItemTemplate. This is because, I want to save all rows in grid on server side, instead of using BatchEditing update/save events. And EditItemTemplate control is not accessible on server side, on Button Click Event.

<telerik:GridTemplateColumn HeaderText="Category" HeaderStyle-Width="150px" UniqueName="Invoice_Category_ID" DataField="Invoice_Category_ID">
                        <ItemTemplate>
                            <input id="hdnCategory" type="hidden" runat="server" value="" />
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox RenderMode="Lightweight" runat="server" ID="CategoryDropDown" DataValueField="Invoice_Category_ID"
                                DataTextField="Description" OnItemsRequested="CategoryDropDown_ItemsRequested"  EnableLoadOnDemand="true">
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

Hello Azam,

You can check the sample at the end of this article for accessing controls from other cells:
https://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/edit-mode/batch-editing/validation

You can also check the following code-library:
https://www.telerik.com/support/kb/aspnet-ajax/details/access-telerik-controls-on-client-side

In addition, I am attaching a sample RadGrid web site with accessing the value when it is present in the batch manager.

I hope this will prove helpful.

Hi Eyup,

Thanks for response, but this is not something I need. I can get reference of control placed in edititemtemplate or its value. But I cannot get reference of control placed in ItemTemplate. Like in example provided by me. I want to set value of hidden input control, when value in dropdown changes or when BatchEditClosed. Now I know, how to get value of "CategoryDropDown" placed in edititemtemplate but I can't get "hdnCategory" placed in ItemTemplate of same column. So I can store value for later use.

And I have a reason to do this. On server side, I want to access dropdown selected value for each row on button click.


<telerik:GridTemplateColumn HeaderText="Category" HeaderStyle-Width="150px" UniqueName="Invoice_Category_ID" DataField="Invoice_Category_ID">
                        <ItemTemplate>
                            <input id="hdnCategory" type="hidden" runat="server" value="" />
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox RenderMode="Lightweight" runat="server" ID="CategoryDropDown" DataValueField="Invoice_Category_ID"
                                DataTextField="Description" OnItemsRequested="CategoryDropDown_ItemsRequested"  EnableLoadOnDemand="true">
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

Hi Azam,

You can replace the HTML input element with a server-side HiddenField control and access it on server-side by using the gridItem.FindControl("MyHiddenFieldID") approach:
