Hello I'm adding controls to a radCalander and to TooltipManager dynamically.
the controls are added to the rad calander and to the TooltipManager on dayRender event. days added to the current displayed month displayed properly and are working properly,controls added to days beyond the 15 of the next month are added and displayed properly but do not invoke the tooltipManager.
I noticed they are beeing added with day render When U page to to the next month, and not on PageLoad like those who work properly.
Is there a solution to this problem or instructions on were to add tooltipmanager tooltips so that they will work on months beyond the current.

Error collapsing a Grid Row

I have a grid with a MasterTable and a DetailsTable.

If I expand a row on the MasterTable I can, as you would expact, collapse it again.

If, however, I select a row in the DetailTable and then try and collapse the MasterTable row, I get the following JScript error (in IE8)...

"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Collection was modified; enumeration operation may not execute."

I haven't got any client-side script of my own so it's nothing I've done (at least, not knowingly).

FWIW, the error is reported 62,099 characters in to line 6 of MicrosoftAjax.js.

Anyone any ideas why?

Templated Login control inside RadAjaxPanel -- Validation changes to server-side after first callback

I'm using Visual Studio 2010 Ultimate/Framework 4.0 final and "Telerik RadControls for ASP.NET Ajax 2010.1.415.40" in a normal web application.
I have a Templated asp:Login control inside a RadAjax Panel; like this:

                                                    </div> 
        
                                                    <div class="message-field"> 
        
                                                        <asp:Literal ID="FailureText" runat="server" EnableViewState="False"></asp:Literal> 
        
                                                    </div> 
        
                                                </fieldset> 
        
                                            </LayoutTemplate> 
        
                                        </asp:Login> 
        
                                    </telerik:RadAjaxPanel>

If I remove the ClientEvents-OnRequestStart="function() {return false;}" form RadAjaxPanel, the client-side validation only works the first time the page loads. The first time I use a wrong username/password to login, the page comes back with no validator attached! and from now on the page only will validate server-side.
I tried almost everything I found around the internet and nothing seemed to be able to stop this behavior.
The only solution I've came across is that return false on OnRequestStart!
Is there something I'm doing wrong?

Update: and this solution only works in firefox. Tested in IE and the faulty behavior persists...
Update2: I just found out that after the first callback returns, Page_Validators is [ ] while it was [span#cph_l1_UserNameRequired.validation-error, span#cph_l1_PasswordRequired.validation-error] at the first load...
I'll try to reconstruct it on ResponseEnd...
Update3: It seems the whole mechanism is lost after the first callback. C# code:

    
            rap.ClientEvents.OnResponseEnd = String.Format("EnableValidators(['{0}', '{1}', '{2}']);", rfvCap.ClientID, rfvPW.ClientID, rfvUN.ClientID);

Javascript (jQuery) Code:

    
            function EnableValidators(list) { 
        
                //Page_Validators  
        
                var a = $(list).filter(function (index, el) { 
        
                    return (document.getElementById(el) != null); 
        
                }).toArray(); 
        
                Page_Validators = jQuery.makeArray($(jQuery.map(a, function (el, i) { 
        
                    return (document.getElementById(el)); 
        
                })).toArray()); 
        
            }

but the validationGroup is lost too; even if I reset the Page_Validators as above and call the Page_ClientValidate("Login1"); client-side function, the page stays valid!

Somebody help!!!

Telerik RadMenu - Menu Bar Image

We are working with the Telerik RadMenu. We want to change the graphic for the Menu Bar, our users need the option to change the graphic that appears at the top left. Our options are to use the Telerik button image or a Menu Bar image without any graphic. Both images contain the menu bar with the circle corner. How do we display the proper menu bar background of the tope left corner and the uploaded graphic from the end-user?

[Solved] Capture page events while using RadAjaxPanel

On each content page I placed code in the Load event when Postback is true and False to capture that the user is still logged in. When the user interacts with the controls inside the RadAjax panel those lines of code in the Load event don't trigger. I also tried the Prerender event but it doesn't seem to trigger that event either.
Problem: on which page event or panel event could I place my code that fires any time a user interacts with controls inside the RadAjax panel?
