The sample code demonstrates how to create a web application that can determine which control causes the postback event on an Asp.net page. Sometimes, we need to perform some specific actions based on the specific control which causes the postback. For example, we can get controls' id property that and do some operations, such as set TextBox's text with ViewState variable. In this sample, we can also transfer some data through postbacks.
