Summary: In this video, we will discuss the ways of posting back page data. We start with the simple way of posting the information back to the same page. For that, we create a simple form that contains user’s first name and last name and a button that submits that information to the page itself. Then, we modify the form to post to another page. The way to do that is to change the PostBackUrl property of the button to the name of the page we are posting to. In the receiver page, we are able to read information from the posting page. We create two text boxes that retrieve the first name and the last name. This is done by asking the PreviousPage to find the needed controls with the method FindControl. Since this method returns a Control, we need to cast the result back to a Textbox. Now that we have the information we need, we create a greeting statement for the user coming from the sender page.
Methodology of the development of example: Good coding standard and simplified design to illustrate the key points.
