Hi All, suppose I have a common ASP.NET page named CommonPage.aspx which has several user controls (e.g. buttons), how may I create a inherited page which inherits the user controls from CommonPage.aspx, however together with its own other user controls (e.g. checkbox ,text box...). Inheritance is simple in Windows Form applications, however, it becomes unclear how I can do that in ASP.NET web applications. Must a lot of HTML code be written in the code file behind (.aspx.cs)?<BR><BR>Appreciate if you could provide some samples!<BR><BR>Thank you.
