Here's one way:

    Private Sub DataGridView1_CellValueChanged(sender As Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
        If e.RowIndex <> -1 Then
            Dim CurrentCell As DataGridViewCell = DirectCast(sender, DataGridView).Rows(e.RowIndex).Cells(e.ColumnIndex)
            If Not CurrentCell.Value Is Nothing Then
                If e.ColumnIndex = 0 AndAlso Not Double.TryParse(CurrentCell.Value.ToString, vbNull) Then
                    MsgBox("Only Numbers Please")
                    CurrentCell.Value = Nothing
                End If
            End If
        End If
    End Sub
End Class

If this doesn't work for you, you'll have to be more specific in your question, and show the code you're having trouble with.
