    I have RadTabStrip and RadMultiPage and i am adding some new Tabs and RadPageViews on Page load. Here is my code

                             RadTab objChildTab = new RadTab();
                            objChildTab.Text = "Tab1";
                            objChildTab.Value = "BAC";
                            objChildTab.PageViewID = "Page1";

            Note :  Here i am able to add Tabs to objRadTabStrip.

                            RadPageView pageView = new RadPageView();
                            pageView.ID = "Page1";
                            pageView.Height = 500;


          But Here i getting error :  

                                              The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases


     Kindly help me to identify that RadTabStrip is allowing me to add new Tabs but RadMultiPage  is not allowing me to add new RadPageViews.

    Hello Susheel,

    This is the right way of adding RadTabs and RadPageViews to the RadTabStrip and RadMultiPage dynamically. At my end using your code they were added and their properties were set correctly as shown in the following screenshot.

    Are you adding other controls in the Page_Load handler?
