Accessing usercontrol text page from .aspx page

Hi All,

I have a .aspx page. Usercontrols are getting added dynamically(NOT REGISTERED IN DESIGN MODE).I am adding the controls like below :-

mypanel.Controls.Add(Page.LoadControl("~/MyUserControl.ascx");

I have a textbox in the user control. I want to access the text box from the aspx page by clicking a button.

Do we have anyway to access the the textbox.

Please let me know.

Any response is appreciated.

Thanks,
Dipankar
