[BindableAttribute(false)]
[BrowsableAttribute(false)]
public virtual Page Page { get; set; }

Property Value

Type: System.Web.UI.Page
The Page instance that contains the server control.

ExceptionCondition
InvalidOperationException

The control is a Substitution control.

This property's value reflects the name of the .aspx file that contains the server control.

The following example overrides the Control.Render method. It uses the Page property to access the Page.IsPostBack property and determine whether the page that contains this control has just been loaded for the first time or is the result of a postback.

      protected override void Render(HtmlTextWriter output) 
	   {
         output.Write("Welcome to Control Development!<br>");

			// Test if the page is loaded for the first time 
			if (!Page.IsPostBack)
				output.Write("Page has just been loaded");
		   else
				output.Write("Postback has occured");
       }
