Notifies the server control that caused the postback that it should handle an incoming postback event.

Namespace:   System.Web.UI
Assembly:  System.Web (in System.Web.dll)

Protected Overridable Sub RaisePostBackEvent (
	sourceControl As IPostBackEventHandler,
	eventArgument As String
)

Parameters

sourceControl
Type: System.Web.UI.IPostBackEventHandler

The ASP.NET server control that caused the postback. This control must implement the IPostBackEventHandler interface.

eventArgument
Type: System.String

The postback argument.

The Page object calls the RaisePostBackEvent method when a postback occurs. This call occurs in the page life cycle after loading and change notification are complete but before prerendering occurs.

The following example uses the RaisePostBackEvent method to notify ASP.NET that a post-back event is raised when a custom userButton server control is clicked.

  Sub DisplayUserName(Sender As Object, e As EventArgs) 
     Response.Write("Welcome to " + Server.HtmlEncode(userName.Text))
  End Sub

 Sub MyRaiseEvent(Sender As Object, e As EventArgs)
     'Raises a post back event for a control.
      Me.RaisePostBackEvent(userButton, "")
 End Sub 

  Sub Page_Load(Sender As Object, e As EventArgs)

    'Registers a control as one that requires postback handling
    Me.RegisterRequiresRaiseEvent(userButton)
End Sub
