Hi,

We are facing an weird problem. We have a RadCaptcha inside an asp:login template and have one RadPanel where this asp:login is inside.
When the Captcha Generate New Machine is asked for, them an AJAX request is started but the interesting is the return: no image at all, captcha is there but the div's responsible for the images are not.
Sample code:

    
                <form id="frmLogin" runat="server">  
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server"   
        
                        HttpHandlerUrl="~/SBP.UI.WebResource.axd">  
        
                </telerik:RadScriptManager> 
        
                <div id="login" align="center">  
        
            <div style="position:absolute; left:0; right:0; top:0; height:35px; background-color:#d9d9d9; text-align:center">  
        
                <img src="/App_Themes/login/logo_sbp.png" width="93" height="35" /> 
        
            </div> 
        
                    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Black">  
        
                    </telerik:RadAjaxLoadingPanel>

Hi,

After changing the login box from an ASP.NET Login template to a "normal" code without the Login component I worked perfectly.

Sample code:

    
                <form id="frmLogin" runat="server">  
        
                <telerik:RadScriptManager ID="rsManager" runat="server"   
        
                        HttpHandlerUrl="~/SBP.UI.WebResource.axd">  
        
                </telerik:RadScriptManager> 
        
                <telerik:RadAjaxManager ID="raManager" runat="server"   
        
                    DefaultLoadingPanelID="rpLoading">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="btLogin">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="rpLogin" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="rcCaptcha">

                </div> 
        
                </form>

May someone point the way we should do for working inside an ASP.NET Login template ?

Hi Daniel,

You should not use both RadAjaxPanel, and RadAjaxManager to ajaxify the same controls. I inspected your code, and I think that you only need the RadAjaxPanel to ajaxify the Login Control. Please remove the RadAjaxManager from the page, and see if you are still getting the problems.
