Property Value

Type: System.Web.UIPage
The Page instance that contains the server control.
Exceptions
ExceptionCondition
InvalidOperationException

The control is a Substitution control.

Remarks

Examples

The following example overrides the ControlRender method. It uses the Page property to access the PageIsPostBack 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 Overrides Sub Render(output As HtmlTextWriter)
   output.Write("Welcome to Control Development!<br>")

   ' Test if the page is loaded for the first time 
   If Not Page.IsPostBack Then
      output.Write("Page has just been loaded")
   Else
      output.Write("Postback has occured")
   End If 
End Sub
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");
       }
