'Usage
Dim instance As SaveBeforeNavigationControl

public sealed class SaveBeforeNavigationControl : WebControl,

Remarks

This control prevents data loss on publishing pages. When a page is in edit mode, and a user navigates to another page without executing __doPostback, this control automates the save process before the page is exited (using Internet Explorer's onBeforeUnload event). This can occur when a user clicks a link or closes the browser. This control is included by default on Publishing pages.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
