GridButtonColumn CommandName Delete

[Jean-Marc Windholz]

It must be very simple but I can't work it out
I've got a grid

<telerik:RadGrid ID="RadGrid1"
                            runat="server"
                            ShowHeader="False"
                            AutoGenerateColumns="False"
                            >

                <MasterTableView
                                    DataKeyNames="AppID, IDCart, IDOrder">

                    <Columns>

..............

                        <telerik:GridTemplateColumn UniqueName="TemplateColumn" >
                            <HeaderStyle Width="335px" />
                        <ItemTemplate>
                                <asp:Literal ID="myLiteral" runat="server" />
                          </ItemTemplate>
                       </telerik:GridTemplateColumn>

                        <telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"
                            ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" Text="Delete"
                            UniqueName="DeleteColumn">
                            <HeaderStyle Width="15px" />
                            <ItemStyle HorizontalAlign="Center" CssClass="MyImageButton" />
                        </telerik:GridButtonColumn>

                    </Columns>
                </MasterTableView>
        </telerik:RadGrid>

(myliteral is filled on temDataBound event.)
I bind the grid on code behind needdatasource event. It works fine.
If I click the GridButton to delete, raising RadGrid1_DeleteCommand event, it performs the delete function. It works fine


Now I just need to add Ajax to this.
so

<telerik:RadAjaxManager ID="RadAjaxManagerCart" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                        <telerik:AjaxUpdatedControl ControlID="myLiteral" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>

It is not working. The RadGrid1_DeleteCommand event is performed, but it does not refresh the grid

Could you help me please?

any idea anyone?

Hello Jean-Marc,

There is no visible reason as to why this approach is not working in your scenario. I created a runnable website based on your code - it is working as expected on my end.
Please give it a try and let me know if I'm missing something.

Note that you don't have to update the nested Literal since the parent control is already ajaxfied.

My problem had a completely different source. Sorry for that.
I forgot an earlier Response.write in the page load event in the If Page.IsPostBack. Ajax does not like that too much

Hi all,

I want some information about  GridButtonColumn's default images or default command name , for example when columns name set to delete - then delete image get display .

[Eyup]

Hello Rohan,

You could refer to the GridButtonColumn section of the following topic and the provided link there to get a better idea of command names:
http://www.telerik.com/help/aspnet-ajax/grid-column-types.html

In case you set the CommandName of the ButtonColumn to Delete or Edit and set the ButtonType as ImageButton, a corresponding Image will be displayed depending on the chosen Skin. This is similar to the scenario when you have GridEditCommandColumn or GridClientDeleteColumn with ButtonType as ImageButton.

I hope this will prove helpful. 

Kind regards,
Eyup
