I have a simple RadTagCloud on a page which has a relatively complex layout. The items in the tag cloud are the result of a query and clicking the item perform additional queries, some of which can take some time to complete. I want to show an Ajax loader image (rotating dots) inside the ProgressTemplate of a .NET UpdatePanel. The problem I have is that clicking the link cuased the page to postback rather than showing the updater image. To illustrate this point...

I have a simple button on the page which when clicked shows that AJAX is being implemented

 Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        System.Threading.Thread.Sleep(2000)
 End Sub

However, the RadTagCloud (AutoPostBack=true) control performs a post back and reloads the page

Private Sub cloudAttractions_ItemClick(sender As Object, e As Telerik.Web.UI.RadTagCloudEventArgs) Handles cloudAttractions.ItemClick
System.Threading.Thread.Sleep(2000)
End Sub

Is there a solution to this problem?

hi
I have a user control that is ajaxified by RadAjaxManagerProxy ,
I've also used a ToolTipManager that is ajaxified by setting it's OnAjaxUpdate property

It works well on page , but if I put this UserControl inside a ContentTemplate of a RadWindow in RadWindowManager
like this : 
    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="True"
        Skin="Office2010Blue">
        <Windows>
            <telerik:RadWindow ID="ContainerBrowser" runat="server" Title="Container Browser"
                Modal="true" Behaviors="Maximize,Close,Minimize,Move,Resize">
                <ContentTemplate>
                    <uc3:SkinBrowser ID="SkinBrowser1" runat="server" SkinType="Container" /> <<-- my user control
                </ContentTemplate>
            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

I get this error : 




Cannot unregister UpdatePanel with ID 'ToolTipManager1RTMPanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.

I really have no idea to fix this problem
Thank you very much for your help

I am using a RadDateTime Picker and different controls like dropdown list etc on a ASP.Net web user control, And  I have RadAjaxLoadingPanel and RadAjaxPanel in my ASP.Net page.
Now when any event gets fired from any controls of the user control, it does display a loading panel in the main page; although the events fire properly and the page is updated.
The problem causing is that the loading panel not displaying only when the RadDateTime Picker selected the first time, Once we selected a date and try to change the selected date this time the loading panel works properly.
Note that the usercontrols are not added dynamically, they exist when the page is loaded.
Can anyone please guide me with an alternative way of achieving this? Or if I am missing something? I am not using AjaxManager in the ASP.net page.

Recently, we updated Telerik library from Q2 2010 to Q2 2011 and everything was good except the sliders i.e. pagers and only in all versions of IE (see attachments). Firefox and Chrome do not have the problem. Is there any idea how to fix that?

Thanks.

Hello all -

I have the following scenario:

A main page using MasterPage.master.
In the main page a tab strip using multipageview.  The multipageview content is using subMaster.master.

I would like to call a RadWindow from the control in the multipageview that covers the entire browser window.  I can call one in the control page no problem, but it is only modal to the page calling it, not the main page.

Any clues to get me going in the right direction would be much appreciated.

Thanks.

I am trying to override the default CSS for RadGrid but still it is taking the Original RadGrid_Default style effects.Please let me know where to modify.
Waiting for response.
