Private Sub dgv1_CellParsing(ByVal sender As Object, _
        ByVal e As DataGridViewCellParsingEventArgs) _
        Handles dgv1.CellParsing
    Dim dgv As DataGridView = CType(sender, DataGridView)

    If dgv.Columns(e.ColumnIndex).Name = "Column1" AndAlso _
            e.DesiredType Is GetType(String) Then
        e.Value = e.Value.ToString().ToUpper()
        e.ParsingApplied = True
    End If
End Sub

C#

private void dgv1_CellParsing(object sender,
    DataGridViewCellParsingEventArgs e)
{
    DataGridView dgv = (DataGridView)sender;

    if (dgv.Columns[e.ColumnIndex].Name == "Column1" &&
        e.DesiredType == typeof(string))
    {
        e.Value = e.Value.ToString().ToUpper();
        e.ParsingApplied = true;
    }
