After you complete the data source wizard the Form View will have controls added to it for the Item Template, Edit Item Template, and Insert Item Template.It is the Edit Item Template you are interested in.
Here we are not looking for Label controls in Item Template, but Text Box controls in Edit Item Template (Edit Item ! Also we want to bind the right row of data (Displayed Index == Edit Index). JPG Now the Edit Item Template is rendered with data bound to Text Box controls.They make it easier to build webpages that access, display, manipulate, and save data. You use these controls to configure access to data that you intend to use on a webpage.Using these controls can provide development efficiency when you are building business applications that rely heavily on data. A data source can be a relational database, data stored inside of in-memory objects (such as a Data Set or an Entity Data Model), XML-based data, or data you retrieve via Microsoft Language-Integrated Query (LINQ).This will be more clear as we get to the other event handlers.After we call Data Bind method Item Data Bound event is fired.Now that we are, we are binding new updated Data Set in this event handler.
Clicking on Cancel button Item Canceling event is fired.
The next step is to change out a Text Box for a Drop Down List in the Edit Item Template and get data into the Drop Down List.
To demonstrate data binding for a Drop Down List in a Form View switch the Form View to the Edit Item Template.
The second lesson in this chapter demonstrates how you can bind to data to allow users to interact with it.
The lesson covers using web server controls such as Grid View, Repeater, Details View, and many more.
Controls that use this method with Data-Binding Expression are Grid View, Details View, Form View, Repeater and List View.
