Commanditem button as RadWindow opener

[Fit2Page]

When I have a button in RadGrid commanditem as follows:

    <CommandItemTemplate>
        <div><asp:Button ID="btn_stats" runat="server" Text="Omzet statistieken"></asp:Button></div>
    </CommandItemTemplate>

 

And I want to use that button as RadWindow opener like:

    Protected Sub dtgProducts_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs)
        If TypeOf e.Item Is GridCommandItem Then

            Dim commandItem As GridCommandItem = CType(e.Item, GridCommandItem)
            Dim button As Button = CType(commandItem.FindControl("btn_stats"), Button)

            ViewState("statsopener") = button.ClientID
            rw_Stats.OpenerElementID = button.ClientID
        End If

    End Sub

I try to assure the OpenerElementID on paging the RadGrid like:

    Protected Sub dtgProducts_PageIndexChanged(sender As Object, e As GridPageChangedEventArgs)

        dtgProducts.MasterTableView.Columns(1).HeaderText = ViewState("statsopener")
        'dtgProducts.AllowPaging = False
        rw_Stats.OpenerElementID = ViewState("statsopener")

    End Sub

 

But the button does not open the RadWindow after paging the grid.

Please assist.

Hi Marc,

RadGrid already provides confirmation functionality. You can use GridButtonColumn to achieve this requirement automatically:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/data-editing/delete-records/adding-a-delete-confirmation

In addition, I am also attaching a sample RadGrid web site to demonstrate more advanced implementation. 
​
Alternatively, if you want to implement a custom approach, you can use GridTemplateColumn and place a Button in its ItemTemplate.

If you want to delete the row only visually on the client, you can use a GridClientDeleteColumn.

NOTE: 

There is a bug in version R1 2017 - DeleteCommand event does not fire with  ConfirmDialogType="RadWindow". You can try to upgrade to version 2017 R1 SP1 to resolve the issue.

Alternatively, you can remove the ConfirmDialogType property and use the default window confirmation:

I hope this will prove helpful.

Hi Eyup,

 

My scenario is not based on a RadGrid column command, but on a button in the

 

<CommandItemTemplate>
        <div><asp:Button ID="btn_stats" runat="server" Text="Omzet statistieken"></asp:Button></div>
    </CommandItemTemplate>

 

Please refer to the code I sent you in my first post.

Hello Marc,

When developing your app, we highly recommend you to ensure that the functionality works without adding AJAX. Please temporarily disable any AJAX on the page if present (RadAjaxManager, RadAjaxPanel, UpdatePanel, etc.) and enable your script debugger (FireBug or F12) to see whether there are any script or server errors interfering, and make sure that the application works without AJAX.

Also, you can check this article:
http://docs.telerik.com/devtools/aspnet-ajax/controls/window/troubleshooting/opening-from-the-server

If the issue remains, please open a formal support ticket and send us a very basic version of your application for further investigation.
