I've boiled this down to a very simple scenario, so it's probably me misunderstanding the intended usage. I see the problem on the following setup:
Dev environment: VS2008 on Vista Business / running application locally on "Cassini"
RadControls: ASP.NET Ajax v. 2.2.7
Browsers: IE8 and Fx 3.0.5

I have a RadDatePicker inside an UpdatePanel. After a partial postback, the calendar popup no longer works. This is part of a large application, but the problem occurs with just the following ASPX code (no modifications to the code file):

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Cal-Text.aspx.cs" Inherits="Cal_Text" %> 
        
            <%@ Register TagPrefix="Rad" Namespace="Telerik.WebControls" Assembly="RadInput.Net2" %> 
        
            <%@ Register TagPrefix="Rad" Namespace="Telerik.WebControls" Assembly="RadCalendar.Net2" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml"> 
        
            <head runat="server"> 
        
                <title>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                <asp:ScriptManager ID="uxScriptMan" runat="server" /> 
        
                <asp:UpdatePanel ID="uxAdditionalChildPanel" UpdateMode="Conditional" runat="server"> 
        
                    <ContentTemplate> 
        
                        <Rad:RadDatePicker ID="uxDate" runat="server" /> 
        
                        <asp:Button ID="uxSubmit" runat='server' UseSubmitBehavior="true" Text="Submit" /> 
        
                    </ContentTemplate> 
        
                </asp:UpdatePanel> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

That's really all there is to it. Any pointers would be appreciated.

Thanks,
WarrenM

Hello Warren,

I followed your scenario in order to replicate the issue but to no avail. Find attached a small runnable application, which is working as expected. Give it a try and let me know how it goes or if I am leaving something out.

Hello Monika,

The code I used in the attached project is the same that Warren provided in the first post and as I pointed out it is working without problems. Therefore in order to assist you further with your issue please specify which is the version of Telerik UI controls you are using and the browser in which you run the page. Did you manage to replicate the problem with the latest version of the controls?
