View 2 RepliesI'm trying to create new tabs within page. When I click a link in my navmenu, it should open the Redirected page in a new tab within the page as new tab (not the browser tab). It is something like the visual studio, where we get the page opened inside a new tab when you click an item in the Solution explorer. Would any body let me know how to implement this functionality. (generate tab with close functinality). I m not talking about TabStrip.

apologies beforehand for what can possibly be a daft conceptual question. I have an ascx control that has a bunch of ASP labels and buttons in the ascx page and some other public methods and properties in the code behind. When I drop this ascx control in a page it all works fine. I now have a page with a placeholder and I am trying to dynamically create an instance of my ascx control and put it there. I then reference this control in code and while all public methods and properties are available (ie MyControl.TitleString = "Hello";MyControl.DoSomething();) none of the ASP controls are. Rather, they are all null. So MyControl.buttonSave is null, MyControl.LabelTitle is null, etc. Is this by design? Am I missing something? If not, what's the point of being able to create dynamically do this?
