Simple Data Field

Referred to as a “bound column” in ASP.NET, the Simple Data Field column lets you specify which data source field to display, and the data format the field will use with a .NET formatting expression.

Free Form

Referred to as a “template column” in ASP.NET, the Free Form column type lets you create combinations of HTML text and server controls to design a custom layout for a column. The controls within a free-form column can be data-bound. Free-form columns give you added flexibility in defining the layout and functionality of the grid contents, because you have complete control over how the data is displayed and what happens when users interact with rows in the grid.

Hyperlink

The Hyperlink column displays information as hypertext links. A typical use is to display data (such as a customer number or product name) as a hyperlink that users can click to navigate to a separate page that provides details about that item.

Edit, Update, Cancel Buttons

Referred to as the “edit command” column in ASP.NET, the Edit, Update, Cancel Buttons column lets users perform in-place editing of information in DataGrid rows. To do so, create an Edit, Update, Cancel Buttons column. At run time, this column displays a button labeled Edit. When the user clicks the Edit button, the row data is displayed in editable controls such as text boxes, and the Edit button is replaced with Update and Cancel buttons.

Delete Button

The Delete Button lets a user delete a particular row by clicking a button.
