Assertion failed length of elements and json must be the same

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

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 Sub

How do I override the RadAjaxManager DefaultLoadingPanelID

I've specified a DefaultLoadingPanelID in my master page's RadAjaxManager, but there are some instances where I do not want a loading panel to appear. Is there a way to override that default setting and specify (e.g. within a page's RadAjaxManagerProxy?) that an AjaxUpdatedControl element should not have any associated LoadingPanel? I tried setting the AjaxUpdatedControl's LoadingPanelID="" but the default loading panel was still displayed.

Thank you,
Tom Huleatt

ExportToPDF() functionality not working with RAD EDITOR

Hello,
         I am using the RadEditor in my application.
         I have seen the demo to covert the RadEditor content to PDF on Telerik Site

           PDF Export
        Now, I tried to used the code which is shown in the example,but it gives me the error of ContentFilters.
            I think the error is due to version,
   I am using the old version of telerik components : ASPNET AJAX Q3 2008.

            Should i need to change my version..

If yes, then which version i required to have the above functionality ?.
Also, how should i upgrade the new version in my application ?.
will it affect any of the other pages functionality or application ?

          I need the above feature in my application as soon as possible,
          Please reply.

Thanks,
Kunal Patel

Optimizing ContentFilters performance

We have a web forms page with multiple rad editors on it. All editors have the ContentFilter property set to "DefaultFilters". Upon clicking a postback button, there is a lag in the submission due to the contentfilters of the radEditors being applied.

I am trying to optimize performance by only turning on those filters that are necessary to insure XHTML compliance of the output. There is a filter titled "ConvertToXhtml". Additionally, there are filters titled "ConvertFontToSpan" and "FixUlBoldItalic". If I have "ConvertToXhtml" turned on, are these other two filters redundant, since when you convert the content to XHTML, won't it convert <font> and <u> tags to <span> tags? If so, should I just apply the "ConvertToXhtml" filter and turn these other two filter off?

Also, I have followed your guideline on optimizing RadEditor performance (for example, http://www.telerik.com/community/forums/aspnet-ajax/editor/radeditor-performance-issue.aspx and http://www.telerik.com/support/kb/aspnet-ajax/editor/radeditor-loads-slowly-high-cpu-utilization.aspx). Do you have any other recommendations for speeding up the processing of the RadEditor content by the ContentFilters?

Thanks so much for your assistance.

                       </telerik:RadGrid> 
        
                    </telerik:RadAjaxPanel>

with this code behind:

    
             protected void Page_Load(object sender, EventArgs e)  
        
                    {             
        
                    }  
        
             DateTime totalTime = new DateTime();                  
        
                    protected void Grid1_ItemDataBound(object sender, GridItemEventArgs e)  
        
                    {  
        
                        if (e.Item is GridDataItem)  
        
                        {  
        
                            GridDataItem dataItem = (GridDataItem)e.Item;  
        
                            totalTime = totalTime.AddSeconds(Double.Parse(dataItem["itm_VTR"].Text));  
        
                        }  
        
                        else if (e.Item is GridFooterItem && endTime < castLength)  
        
                        {  
        
                            GridFooterItem footer = (GridFooterItem)e.Item;  
        
                            (footer["TemplateColumn"].FindControl("txtTotalTime") as RadTextBox).Text = totalTime.ToString("HH:mm:ss");  
        
                        }  
        
                    }

My problem is with the calculation(see code behind in Grid1_ItemDataBound), which are displayed in "txtTotalTime" textbox, without paging the calculations work fine. However with paging, each page of the grid behaves like an independent grid and on each page i get the calculations of items of the current page only and not for the entire grid. I need to see on each page of the grid the calculation of all items of the grid.

I would appreciate any help.

Best Regards
Yuri

Which client event after server side filter?

Hello,

I have a RadGrid which uses the NeedDataSource event to allow the built in filtering to work. I need some client side code to run when the grid reloads with the filtered results, or, as each row is removed/added. The description of the events is pretty vague, for example, http://www.telerik.com/help/aspnet-ajax/grid_onrowcreated.html, does not specify if the event is only meaningful for client-side data binding, whereas I know some methods do.

So the question is, how can I respond to a grid in javascript when it has been or is being filtered? The end result is to update an image gallery that corresponds to the grid, any rows that get filtered out have their images in the gallery hidden and vice-versa.

Regards,

Mark Leavesley

How to use the Telerik icons in HTML?

I read this http://www.telerik.com/help/aspnet-ajax/grdskins.html and it seems I can use the Telerik icons in HTML, I need to do some customization on RadGrid.

Anyone knows how to use it in an ASPX page? Since it is already embedded in web resource already.

<img src="......[some web resource path]....Edit.gif" />

Of course the stupid way is to download all images in my web application and reference it as ~/Images/Edit.gif.

Thanks
