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

protected virtual PostBackOptions GetPostBackOptions()

Return Value

Type: System.Web.UI.PostBackOptions

A PostBackOptions that represents the ImageButton control's postback behavior.

The GetPostBackOptions method creates a PostBackOptions object that represents the ImageButton control's postback behavior. The PostBackOptions object is then typically passed to the ClientScriptManager.GetPostBackEventReference(PostBackOptions) method, which is used to obtain a reference to a client-side script function that, when invoked, causes the server to postback to the page.

This method is used primarily by control developers when extending the ImageButton class.

Notes to Inheritors:

You can override the GetPostBackOptions method in your derived class to modify the postback options for the button control, or to call client-side script when the button is clicked. Be sure to call the base class's GetPostBackOptions method so that the standard postback options are set.
