Q2 2011 Service Pack 1 (Version 2011.2.915)

Breaking change: Now all HTML 5 compliant browsers, which support the File API interface (FireFox 4.0+, Chrome latest, Safari 5.0+), use the File API module.

Reason: Numerous of problems with the Silverlight/Flash plugins in browsers different than IE. The FileAPI module provides the same features as Flash/Silverlight with one exception. It is not yet possible to display extensions filter within the select file dialog. However, this functionality is part of the input[type='file'] specification and it is about time that the browsers implement it.

Problem: Using the Flash module in IE6/7/8 debug information is displayed into the Developers Bar JavaScript console.

Reason: Non commented console.log invocation within the ActionScript code.

Solution: The problem will be resolved in the upcoming Latest internal build.

Q2 2010 (Version 2011.2.713)

Problem: RadAsyncUpload sometimes fail to upload the files to the target folder.

Reason: The temporary files, which RadAsyncUpload uses internally to save the uploaded files to the target folder, are being deleted too early, hence leaving the upload without files to save.

Solution: We have fixed the problem for the latest internal build (version 2010.2.722+). More information on how to obtain the latest internal build can be found here.

Alternatively, you can do the following:

Step 1: Add an ashx handler to your app. Inside, use the following code:

<%@ WebHandler Language="C#" Class="CustomHandler" %>

using System;

using System.Web;

using Telerik.Web.UI;

public class CustomHandler : AsyncUploadHandler {

protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration configuration, string tempFileName)

{

configuration.TimeToLive = TimeSpan.FromHours(4);

return base.Process(file, context, configuration, tempFileName);

}

Then, set the HttpHandlerUrl property of RadAsyncUpload to point to that handler. Like this:

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" HttpHandlerUrl="~/CustomHandler.ashx" TargetFolder="~/Documents">

</telerik:RadAsyncUpload>

Other issues:

SOLUTION: Upload fails OR Login prompt appears when using Forms / Windows Authentication

Rad Editor Lite Does Not Pass SPDisposeCheck

We are using RadEditor LIte on SharePoint/MOSS 2007. When checking for memory leaks with SPDisposeCheck, RadEditor is listed as not disposing of all its memory. Is this a false positive? We are on version 4.5.3.0 but checked the dll for the newer version, and it still does not pass the SPDisposeCheck.

Thanks, Connie

Fail to load components after licensing

Hi,
I'm developing on Win7 with VS2008 SP1, IIS7.
The production server is Windows 2008 R2 with IIS7.

After moving from the trial version to the licensed version, everything looks perfect in the development environment, but in the production no images are loaded (chart appears as red X and menu are only textual).
I read some threads on the forum regarding this issue but as I said, I'm using VS2008 with SP1 and both environments has IIS7.

Below is a copy of my web.config file.

What have I done wrong?
Thanks,
Niv.

Problems with onajaxload and Radtooltipmanager

Hi Guys,

After sorting out my recent problems getting radtooltip to work inside a datalist I found out i can't use Load on Demand with a tootip, only with a tooltip manager so I have had to rewrite it all to get it working. However I am having lots of problems.

First of all here is my code.

<%@ Page Language="VB" MasterPageFile="Master.master" %> 
<%@ MasterType  virtualPath="Master.master"%> 
 
<%@ Import Namespace="System.Configuration.ConfigurationManager" %> 
<%@ Import Namespace="System.Data" %> 
<%@ Import Namespace="System.Data.SqlClient" %> 
<%@ Import Namespace="System.collections.Generic" %> 
<%@ Import Namespace="Tvi" %> 
 
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
 
 
 
<script runat="server"> 
     
    Dim Reader As SqlDataReader 
    Dim Files As String = AppSettings("files_url") 
 
    Sub Page_Load() 
         
        MyRepeater.DataSource = Database.getDataReader("SELECT TOP 10 Caption, Thumbnail FROM Photos") 
        MyRepeater.DataBind() 
         
    End Sub 
     
     
    Sub MyRepeaterBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs) 
         
        If e.Item.ItemType = ListItemType.AlternatingItem OrElse e.Item.ItemType = ListItemType.Item Then 
             
            Dim TempImage As Image = DirectCast(e.Item.FindControl("MyImage"), Image) 
             
            Dim ClientID As String = TempImage.ClientID 
             
            CommentToolTip.TargetControls.Add(ClientID, True) 
             
        End If 
         
    End Sub 
     
     
    Protected Sub OnAjaxUpdate(ByVal sender As Object, ByVal args As ToolTipUpdateEventArgs) 
        Dim elementID As String = args.TargetControlID 
        'Add content when necessary 
        args.UpdatePanel.ContentTemplateContainer.Controls.Add(New HtmlGenericControl("HR")) 
    End Sub 
         
</script> 
 
<asp:Content ID="Content" ContentPlaceHolderID="Content" runat="server"> 
    <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
     
    <asp:UpdatePanel ID="UpdatePanel1" runat="server"> 
        <ContentTemplate> 
         
         
            <asp:repeater runat="server" id="MyRepeater" onitemdatabound="MyRepeaterBound"> 
                    <itemtemplate> 
                        <asp:image runat="server" id="MyImage" imageurl='<%# Files + DataBinder.Eval(Container.DataItem, "Thumbnail")%>'/> 
                    </itemtemplate> 
                </asp:repeater> 
         
         
        </ContentTemplate> 
    </asp:UpdatePanel> 
     
    <telerik:radtooltipmanager  
        runat="server"  
        id="CommentToolTip"  
        ManualClose="true" 
        Sticky="true"  
        Title="Hello"  
        Skin="Web20"  
        Width="350px"  
        Height="250px"  
        Position="MiddleRight"  
        OffsetX="6" 
        Animation="Fade"  
        OnAjaxUpdate="OnAjaxUpdate"> 
    </telerik:radtooltipmanager> 
         
         
         
</asp:Content> 

I should explain that line 21 uses a function of our own data layer. My problems are as follows....

1) When i remove the OnAjaxUpdate="OnAjaxUpdate" the page works. It shows a blank tooltip when you click on each photo. However, when I add the OnAjaxUpdate back in it stops working. The tooltips show for half a second then disappear again.

It does this in Firefox and IE and does it when i take all of the code out of the onajaxupdate sub too so the problem doesn't seem to be with the contents of that sub.

2) Because I am now using a radtooltipmanager rather than a radtooltip inside the datalist i have no idea how to change the title of the tooltip to the "Caption" I am getting from the database. When I was using a tooltip in the datalist I just did this...

Title='<%# DataBinder.Eval(Container.DataItem, "Caption") %>'

3) I copied the OnAjaxUpdate Sub from a telerik example but have no idea what it is doing. WHy is ElementID declared and then not used ? And what is args.UpdatePanel.ContentTemplateContainer.Controls.Add ? Does the Tooltip have it's own updatepanel inside it ?

Any help would be really appreciated as I just don't understand the online demos or the documentation. A very simple example would be useful to many others I'd guess.

Thanks, Jon

Retrieving a SharePoint ListId and ItemId in script

I am attempting to write a extension to the RADEditor to allow for some custom image handling. I have written a COM component to do the custom formatting and just need to pass in the listId and ItemId of the SharePoint list item that is being edited to the method. How would you recommend locating this data from the editor?

Integrating the new tool bar item and javascript code was quite easy and the webUrl I found by:

var

webUrl = editor._dialogParameters["CurrentWebBaseUrl"];

thanks

689K Size problems! - Telerik.Web.UI.WebResource.axd

On an initial load of a page I am seeing one call to WebResource.axd be 689K!

Telerik.Web.UI.WebResource.axd?_TSM_HiddenField_=ctl00_ctl03_TSM&compress=1&_TSM_CombinedScripts_=%3b%3bSystem.Web.Extensions%2c+Version%3d3.5.0.0%2c+Culture%3dneutral%2c+PublicKeyToken%3d31bf3856ad364e35%3aen-US%3a1247b7d8-6b6c-419f-a45f-8ff264c90734%3aea597d4b%3ab25378d2%3bTelerik.Web.UI%2c+Version%3d2010.1.309.35%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3a30afb63f-e6ac-41db-9851-11879733de0a%3a16e4e7cd%3a86526ba7%3af7645509%3a24ee1bba%3a1e771326%3aaa288e2d%3a58366029%3aed16cbdc

The page itself has 8 RadCombos, a Grid, a RadWindow control and an RadHXLHTTPPanel. I have the Cdn enabled for ScriptManager. I even have the jscript files local to the site. For the trace, I see the local jscript files being grabbed.

I tried adding telerik compression and it did not help.
