Thanks, I'm using Cell Value Changed currently on a grid with custom validation and have had no problems with display or anything else.

I used this event because I wanted to fire off a certain order of events, but only when the user changes the value of a cell.

To make it more clear when I press Enter for the second time.

If I switch to another control right after editing a cell, my method isn't executed at all.

What's the best place to implement validation logic code and conditional formatting code for a Data Grid View?

EDIT The biggest thing about the Cell Validating event is that you can stop the user from leaving a cell, if the value entered does not pass your validation. Cell Validating Dim header Text As String = _ data Grid View1. Text = "Data Grid View validation demo (disallows empty Company Name)" End Sub Private Sub Form1_Load(By Val sender As System. All Cells Except Header) End Sub Private Sub data Grid View1_Cell Validating(By Val sender As Object, _ By Val e As Data Grid View Cell Validating Event Args) _ Handles data Grid View1. Header Text ' Abort validation if cell is not in the Company Name column. Equals("Company Name") Then Return ' Confirm that the cell is not empty. column, its value is tested for validity by checking that it is not empty.

If the event handler for the Cell Validating event finds that the value is an empty string, the Data Grid View prevents the user from exiting the cell until a non-empty string is entered.

Now, since so many books use the Cell Validating event, I wonder if there is not any gotcha (in display for example) with using the Cell Value Changed?
