when i try to validate the datagridview cell which evet should i use in the datagrid view.i and using the dgv Actions_Cell Validating event,but the thing is i want to validate the cell after the cell value has been selected.The Event Args usually has a Cancel property that if set to true will block the user from leaving the data entry field (cell, textbox, etc.).They are only triggered when the user tries to leave a field because only then can we be certain that the user has finished entering the value.

See the image the information is provided there..., which are in blue color they are readonly ......
I tried and i get the answer to true won't allow user to leave current cell as long as value is not valid one.
I recommend setting the Cancel property to true for invalid data as then the user focus will remain in cell 2. (inside your column test) events are used to help stop the user from leaving a cell with a bad value.
