Assertion failed length of elements and json must be the same

[A K]

I have radPanel bar on a page to which I am adding panel items dynamically with user controls.  I want to Ajaxify the radpanel item. When user clicks on Save button on the user control I just want to post that current PanelItem. I am trying to do this by following code. I get Error   Assertion failed length of elements and json must be the same.

This is the code to Add item dynamically:

            With radPanelNew

                  .Text = account.Name.ToString

                  .Value = account.Id.ToString

                  .Font.Italic = True

                  .Font.Underline = True

                  .Font.Size = 10

                  '.ID = account.Id.ToString

            End With

           

            Select Case account.Type.Text

                  Case Entities.Account.AccountType.Bank.ToString

                        If account.SubType.Text = Entities.Account.SubAccountType.Savings.ToString Then

                              Dim ucSavings As SubscriberSetupPages_UserControls_SavingsAccount = CType(LoadControl("~/SubscriberSetupPages/UserControls/SavingsAccount.ascx"), SubscriberSetupPages_UserControls_SavingsAccount)

                              ucSavings.AccountID = account.Id

                              ucSavings.ID = "SA" & account.Id.ToString

                              acct = DirectCast(ucSavings.FindControl("acct1"), SubscriberSetupPages_UserControls_Account)

                              radPanelNewChild.Controls.Add(ucSavings)

radPanelNew.Items.Add(radPanelNewChild)

            With radParentItem

                  .Items.Add(radPanelNew)

                  .DataBind()

                  .Expanded = True

            End With

This is the code to Ajaxify radpanelitem:

 

      Private Sub pnlBarAccounts_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadPanelBarEventArgs) Handles pnlBarAccounts.ItemCreated

            ' Following code is to Ajaxify RadPanelItem

            Dim acct As UserControl

            If e.Item.Controls.Count > 0 Then

                  If Not IsNothing(e.Item.Controls(0)) Then

                        If Not IsNothing(e.Item.Controls(0).ID) Then

                              Select Case (e.Item.Controls(0).ID.ToString).Substring(0, 2)

                                    Case "SA"

                                          acct = DirectCast(e.Item.Controls(0), SubscriberSetupPages_UserControls_SavingsAccount)

                              End Select

                        End If

                  End If

            End If

            If Not IsNothing(acct) Then

                  Dim btnSave As ImageButton = DirectCast(acct.FindControl("btnSave"), ImageButton)

                  If Not IsNothing(btnSave) Then

                        RadAjaxManagerProxyAcctSetup.AjaxSettings.AddAjaxSetting(btnSave, e.Item)

                  End If

            End If

 

      End Sub

Hi A K,

Could you please verify whether the error appears if the Ajax is disabled on the page.

yes it works fine when Ajax is disabled. As soon as I enable Ajax, control is seen on the page but it goes in javascript error.
