Because this is meant to be a quick example I don’t want to spend a lot of time helping the reader get the database set up, so I’m using the built-in ASPNETDB. To do approach #2, go to the Data Set, click on the Table Adapter and select F4 to open its Properties dialog.
User ID, First Name and Last Name are template columns and Edit and Delete columns are Command Columns which are added using smart tag option (You can view the smart tag if you right click on the Grid View control).

Most web applications get data from the middle tier and display it in a nice-looking HTML layout. For example, the Label control in Listing 1 will update its Text property only when it receives a Data Binding event. As a developer, you have the power to trigger data binding events for individual controls (including child controls) or for all controls within a page. Subsequently, any controls with a data binding expression will update themselves.
I have no earthly idea why the Update command wants to update the key columns by default.The project files are also attached with this article so please feel free to download them.As you can see in the image above our Grid View contains five columns.Raise your hand if you’ve written a web application that couldn’t be cataloged as a data-driven application. To data-bind all the controls in a page, you need code like that in Listing 2 (below).I’m betting that you didn’t raise your hand, because the definition of a data-driven application is quite blurred and flexible enough to incorporate nearly everything. NET controls, behaviors are attached to the control’s life cycle through the Data Binding event handler. It’s the page—if you properly instruct it to do so. Calling the Data Bind method has the effect of triggering the Data Binding event for all the controls in scope.
