basic concepts -> manipulationg data -> validating data says:
The moment when the content of a cell is validated is determined by the ValidationMode property of the DataGridControl class. If set to <b> CellEndingEdit (default) </b>, the value of each cell will be validated when it leaves edit mode (i.e., the focus is moved to another element). If set to RowEndingEdit, the value of all the cells in the row that is currently being edited will be validated when the row leaves edit mode.
ValidationMode Property says:
A ValidationMode value representing when the content of a cell is validated. By default, <b>ValidationMode.RowEndingEdit</b>.
Hope this helps,
