The built-in column types are sufficiently varied and configurable to provide for most of the functionality you’re likely to need, but in cases where further customization is required, you can make the desired changes using templates. Despite these alterations, the current functionality hasn’t changed: you can still execute your project and load the address book, and it will continue to work as before. The “ed” events, on the other hand, should perform the actual task of the button. We saw such an event handler when we handled the Protected Sub grid_Selected Index Changing(By Val sender As Object, ➥ By Val e As Grid View Select Event Args) ➥ Handles grid. We’ll focus on the events that relate to editing and updating data, as our next goal will be to allow users to edit employee details in the buttons. These features are fairly amazing, because you can achieve this “edit mode” without writing any HTML at all: the columns know how to render their editable modes by themselves.
A Details View Updated Event Args object is passed to the event handler, which allows you to determine the number of rows affected and any exceptions that might have occurred.
