ASP.NET in a Nutshell

ButtonColumn

Synopsis

The ButtonColumn class represents a type of column that can be used in a DataGrid control. This column consists of buttons that raise the DataGrid.ItemCommand event. These buttons can be displayed as graphical push buttons (like Button) or text links, depending on the ButtonType property.

The Text property determines what text is displayed for the button, while the CommandName property specifies a string of additional information that will be sent to the DataGrid.ItemCommand event through the DataGridCommandEventArgs object.

If you set the Text and CommandName properties, all buttons in the column will share the same information. Alternatively, you can set the DataTextField property to use data binding and the DataTextFormatString property to specify formatting rules.
