Remarks

A command column provides a set of commands that allow end-users to switch the ASPxGridView to edit mode, update data, delete rows, etc. A single command is represented by a command item.

There are seven command items:

New (ASPxGridViewCommandButtonSettings.NewButton)
Edit (ASPxGridViewCommandButtonSettings.EditButton)
Delete (ASPxGridViewCommandButtonSettings.DeleteButton)
Select (ASPxGridViewCommandButtonSettings.SelectButton, GridViewCommandColumn.ShowSelectCheckbox)
Update (ASPxGridViewCommandButtonSettings.UpdateButton)
Cancel (ASPxGridViewCommandButtonSettings.CancelButton)
Clear (ASPxGridViewCommandButtonSettings.ClearFilterButton)

A command column allows multiple command items to be displayed within a cell.

By default, a command item is represented by a link. It can also be represented by a button or image. Use the GridViewCommandColumn.ButtonType property to specify how the command column renders its command items.

Note

The ASPxGridBase.KeyFieldName property should be specified when using the following grid features:

data editing;
adding new and deleting existing row;
selecting row;
master-detail view;
endless paging.
