The formview fired event itemupdating
With the Form View (or any of the Data Views), I normally use a Data Source to move data from some data store and into/out of the view.However, the Form View (and the rest of the Data Views) will work just as well with any collection of objects: Lists, Arrays, Array Lists, or whatever collection you want to make available to the user for display and update." The Details View control is not limited to exposing its data to users in an appropriate and friendly way.The control also provides interactive buttons to navigate data and edit and insert new records. But you can skip the Data Source and use the Data Views to handle displaying and updating any collection of objects you want, with a few lines of code.
The lesson covers using web server controls such as Grid View, Repeater, Details View, and many more.
NET data source controls, demonstrates how you can bind to data to allow users to interact with it, and presents the new Dynamic Data features of ASP.
NET that allow you to easily create websites for working with the CRUD operations of an entire data model that exists as either a Data Context (such as LINQ to SQL) or an Object Context (such as LINQ to Entities). NET provides several server controls that build on top of the features of Microsoft ADO. These controls simplify the development of data-driven websites.
As you can see we are checking if this is "view mode" or "edit mode" to bind the right data to the List View control.
This will be more clear as we get to the other event handlers.
