CommandItemTemplate with Ajaxified Grid

I have an Ajaxified grid wired up to the AjaxLoadingPanel. I am using a command item template in which I have a "Print" option link button. The link calls a client-side script to run a report. The server side event for this link does the following:

Dim myReport As ReportServer.PendingReport = New ReportServer.PendingReport
Dim reportProcessor As New Telerik.Reporting.Processing.ReportProcessor()
Dim result As Telerik.Reporting.Processing.RenderingResult = reportProcessor.RenderReport("PDF", myReport, Nothing)
Dim fileName As String = result.DocumentName + ".pdf"
Response.Clear()
Response.ContentType = "Application/pdf"
Response.Cache.SetCacheability(HttpCacheability.Private)
Response.Expires = -1
Response.Buffer = False
Response.AddHeader("Content-Disposition", String.Format("{0};FileName=""{1}""", "attachment", fileName))
Response.OutputStream.Write(result.DocumentBytes, 0, result.DocumentBytes.Length)
Response.End()

Firing this event causes the following error:

Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.
Common causes for this error are when the response is modified by calls to Response.Write(), response filters,
httpModules, or server trace is enabled. Details: Error parsing near '%PDF-1.6
%
1 0 obj'

Anyone have any idea of how to avoid this other than removing Ajax Manager for the grid?

RadAjaxManager and UpdatePanel.Update()

There appears to be a bug in the way that the RadAjaxManager is updating UpdatePanels, plus the EventName attribute of the AjaxSetting element is not filtering events. If an UpdatePanel named by an AjaxUpdatedControl element is triggered for an update by the RadAjaxManager, and you also execute the .Update() method of that UpdatePanel in your code, the entire contents of the update panel will be removed on the CallBack.

I have been bending over backwards to work around this, but it really needs to be fixed. In my code, I can execute the .Update() method of a single UpdatePanel as many times as I wish without any issues, so it is something in the way that the RadAjaxManager is handling this. As for the EventName not filtering, there is no work-around.

Handle Exceptions in StoreFile of the Custom FileBrowserContentProvider

Dear Support,

I have created a custom class that inherits from FileBrowserContentProvider and have implemented all the neccesary methods. I sometimes require to reject an uploaded file in the StoreFile method due to some business logic but was not able to figure how that could be implemented. Returning a non-empty string and throwing an exception did not work well. Since the class inherited from FileBrowserContentProvider has no access to the Page-derived class, I am not able to add an Error to the page.

Could you please help in directing me to a neat solution to my problem?

Thanks in advance,

Omtara

Hi,
I am using RadComboBox with item template of checkboxes as described in the demo:
http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultcs.aspx

I am setting the checked items using javascript. this code works perfectly on all browsers but IE6. in IE6 the checkboxes are not checked.

Has anybody encoutered such problem?

This is my javascript code:

    
            function onCheckBoxClick(chk) {  
        
                        var combo = $find("<%=cmbExt.ClientID %>");  
        
                        //holds the text of all checked items  
        
                        var text = "";  
        
                        //holds the values of all checked items  
        
                        var values = "";  
        
                        //get the collection of all items  
        
                        var items = combo.get_items();  
        
                        //enumerate all items

External CSS question

Hi,

I link an external CSS file to an Editor from codebehind:

NLtext.CssFiles.Add("~/" & TablePrefixStrip & "/css/telerik.css")

This works OK, the stylesheet is coupled.
But when I try to select classes from this sheet and add it with

NLtext.CssClasses.Add("Links class ", ".link")

it cannot find the classes. I think this problem occurs when a stylesheet is coupled which lies above the root of our CMS.

But even when I try

NLtext.CssFiles.Add("http://f2p-server:8136/css/telerik.css")
NLtext.CssClasses.Add("Links class", ".MarLeft")

It is not working.

Please assist, TIA

In-place editing with popup

I have a telerik grid control and use in-place editing. Since telerik does not support checkboxlist columns, I want to popup a small window with a checkboxlist and a close button when the user clicks on a cell that requires the user to select multiple items. When the close button on the popup is hit, I want to populate the cell with a comma separated list of choices selected. Is this possible and is there an example that I can look into for doing this?

Thanks
