It is the same for the three cells that are filled on form load. This is not the case with any of the already loaded values.

Unforunately it does not seem to work when i try to add a new row to the grid, enter a value and try to leave the cell.

Private Function Does Cell Contain Duplicated Value(By Val int Column To Check As Integer, _ By Val int Current Row As Integer, _ By Val str Value As String) As Boolean Dim bol Cell Contains Duplicate Value As Boolean = False Dim int Cursor As Integer = 0 Do Until int Cursor = Data Grid View1. Count Or Else bol Cell Contains Duplicate Value = True 'Don't check the old value for the cell we're checking. Formatted Value = "A" And Also Does Cell Contain Duplicated Value(5, e. Cancel = True Msg Box("You cannot have more than one A value.") End If If e. Formatted Value = "B" And Also Does Cell Contain Duplicated Value(5, e.

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.

On form load there are 4 items loaded into the grid.

When the form is loaded the first cell that is selected passes the check with no problem. Ivan.f Private Sub Validate Cell Value(sender As Object, e As Data Grid View Cell Validating Event Args) Handles grd Result.
