I've implemented the Load On Demand for the RadTabStrip & RadMultiPage and followed the sample show in http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx . My Second and Third tabs load user controls in them.

This working fine with the Q3 2009 Trial Version, but when I purchased the Q1 2010 Developer Version, this stopped working and I receive and error "Two components with the same id 'mpageMain' can't be added to the application".

Here is my ASPX

And my code behind

                        mpageMain.PageViews.Add(pageView);  
        
                    }  
        
                    protected void tsMain_TabClick(object sender, RadTabStripEventArgs e)  
        
                    {  
        
                        AddPageView(e.Tab.Text);  
        
                        if (e.Tab.PageView == null)  
        
                        {  
        
                            e.Tab.PageViewID = e.Tab.Text;  
        
                        }  
        
                        e.Tab.PageView.Height = Unit.Pixel(e.Tab.Index * 100); 
        
                        e.Tab.PageView.Selected = true;  
        
                    }  
        
                    protected void mpageMain_PageViewCreated(object sender, RadMultiPageEventArgs e)  
        
                    {  
        
                        // Load the User Control  
        
                        //string strUserControl = "~/UserControls/" + e.PageView.ID + ".ascx";  
        
                        //Control objControl = Page.LoadControl(strUserControl);  
        
                        //objControl.ID = e.PageView.ID + "_userControl";  
        
                        //e.PageView.Controls.Add(objControl);  
        
                    }

I can no longer use Q3 2009 as it has the Grid's OnCommand Client Event problem.

Is there anything different to be done for the Q1 2010 version?
