[Solved] Dynamic RadGrid and OnRowDeleted AJAX error

[Bruce]

I am having a bad time with AJAX request and error message after first OnRowDeleted function call: "Multiple controls with the same ID 'ctl00' were found. FindControl requires that controls have unique IDs."

I build my radtabstrip and radpages and radgrids on pageload.

here is my code for code behind.

 Public Function gametemplate(ByVal dt As Data.DataTable) As RadGrid
            Dim g As New RadGrid
            g.ID = System.Guid.NewGuid.ToString
            ' g.EnableViewState = False

            g.AutoGenerateColumns = False
            g.Skin = "Gray"
            g.MasterTableView.DataKeyNames = New String() {"gameid"}
            g.MasterTableView.ClientDataKeyNames = g.MasterTableView.DataKeyNames
            g.MasterTableView.AllowAutomaticDeletes = "true"
            g.ClientSettings.ClientEvents.OnRowDeleted = "deleteGame"


            Dim hColumn As New GridBoundColumn 'home team
            Dim aColumn As New GridBoundColumn 'away team
            Dim sColumn As New GridBoundColumn 'gametime
            Dim statusColumn As New GridBoundColumn 'status of game
            Dim deleteC As New GridClientDeleteColumn
            deleteC.ImageUrl = "/images/cross.png"
            deleteC.ConfirmText = "Are you sure you want to remove game from schedule?"
            deleteC.ButtonType = GridButtonColumnType.ImageButton
            deleteC.UniqueName = "deleteit"
            'Dim templateColumnName As String = "Delete"
            'Dim templateColumn As New GridTemplateColumn()
            'templateColumn.ItemTemplate = New MyTemplate(templateColumnName)
            'templateColumn.HeaderText = templateColumnName

            'Dim dColumn As New GridTemplateColumn() ' delete it
            'dColumn.HeaderText = "Delete"

            'Dim dButton As New GridImageButton(dColumn)
            'dButton.ImageUrl = "/images/cross.png"
            'dButton.OnClientClick = "return confirm('you da man');"
            'dColumn.ItemTemplate.InstantiateIn(dButton)


            With statusColumn
                .HeaderText = "Status"
                .DataField = "status"
                .UniqueName = "status"
            End With
            hColumn.UniqueName = "hometeam"
            hColumn.DataField = "hometeam"
            hColumn.HeaderText = "Home"
            aColumn.DataField = "awayteam"
            aColumn.UniqueName = "awayteam"
            aColumn.HeaderText = "Away"
            sColumn.DataField = "start"
            sColumn.UniqueName = "start"
            sColumn.HeaderText = "Start"

            g.MasterTableView.Columns.Add(sColumn)
            g.MasterTableView.Columns.Add(hColumn)
            g.MasterTableView.Columns.Add(aColumn)
            g.MasterTableView.Columns.Add(statusColumn)
            g.MasterTableView.Columns.Add(deleteC)
            'g.Columns.Add(templateColumn)

            g.DataSource = dt
            g.DataBind()
            Return g

        End Function

        Protected Sub createFieldTabs()
            Dim fields As bo.fieldlist = fbll.getTournamentFields(Me.tournamentid)

            If fields.Count >= 1 Then
                For Each f As bo.Field In fields
                    Dim newtab As New RadTab

                    Dim newpage As New RadPageView



                    newtab.Text = f.name
                    newtab.PageViewID = newpage.ID

                    newpage.Controls.Add(Me.gametemplate(gbll.getGamesForField(Me.tournamentid, f.fieldid)))

                    fieldpages.PageViews.Add(newpage)

                    fieldtabs.Tabs.Add(newtab)

                    If fields.IndexOf(f) <= 0 Then fieldpages.SelectedIndex = newtab.Index
                Next




            End If

        End Sub

Here is my aspx page:

    }
     function deleteGame(sender, eventArgs)
    {
       var gameid = eventArgs.getDataKeyValue("gameid");
       setManager();

       ajaxManager.ajaxRequest(gameid);

    }

    </script>

here is the ajaxrequest function:

        Protected Sub RadAjaxManager3_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManager3.AjaxRequest
            Try
                gbll.deleteGame(Convert.ToInt32(e.Argument))
                'RadAjaxManager3.Alert("Game deleted.")

            Catch ex As Exception

            End Try


        End Sub

Hello Bruce,

Unfortunately we were able to reproduce the problem and will need a bit more time to investigate.
I will update the thread as soon as we  have any details on the behavior.

Hello,

Did you find a solution to this issue?

We are receiving this error: 
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Multiple controls with the same ID 'ctl00' were found. FindControl requires that controls have unique IDs.

This occurs when we click the Update Button on a GridTemplateForm.  The grid is on a user control which is added to a page dynamically.

Thanks,

TFISHER
