Assembly: System.Web.Mobile (in System.Web.Mobile.dll)
When a page is initially rendered, the first form in the page is automatically made active. On subsequent postbacks, another form might be made active, either by programmatically setting this property, or as a result of user navigation through a Link control.
The following example demonstrates how to use the property of a Form control. If the current mobile device allows for access keys for controls, the button will display the access key that submits the form.
The following code sample uses the single-file code model and may not work correctly if copied directly into a code-behind file. This code sample must be copied into an empty text file that has an .aspx extension. For more information, see ASP.NET Web Page Code Model.
