How can I make it when the datagridview value cell value is selected and then the error message display and the cursor is focused in to the same cell. thnxxxxxx I must agree with you on how the Validation events operate. Microsoft is conducting an online survey to understand your opinion of the Msdn Web site.If you choose to participate, the online survey will be presented to you when you leave the Msdn Web site.

However, you can block the move so the focus remains on the current control (cell) by setting the Cancel property to True on the Cancel Event Arg parameter.
