I maded one post about currency formating, and the question was answered, but I am now trying to put the system formatting within a field in a datagridview, so, I C# for me is more easy to make that, and I maded, but, When I tryed to make the same in Visual Cobol, I just got errors :( My C# code is that, remambar, is based in that code: http://community.microfocus.com/microfocus/cobol/visual_cobol/f/18/t/10425.aspx private void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { e.Control.PreviewKeyDown -= Control_PreviewKeyDown; e.Control.PreviewKeyDown += new PreviewKeyDownEventHandler(Control_PreviewKeyDown); } private void Control_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e) { var txtB = (TextBox)sender; var myValue = txtB.Text.Replace(",", "").Replace("R$", "").Replace(".", "").TrimStart('0'); decimal ul; if (Decimal.TryParse(myValue, out ul)) { ul = ul / 100; txtB.PreviewKeyDown -= new PreviewKeyDownEventHandler(Control_PreviewKeyDown); txtB.Text = string.Format(System.Globalization.CultureInfo.CreateSpecificCulture("pt-BR"), "{0:C2}", ul); txtB.PreviewKeyDown += new PreviewKeyDownEventHandler(Control_PreviewKeyDown); txtB.Select(txtB.Text.Length, 0); } if (!TextIsValid(txtB.Text)) { txtB.Text = "R$ 0,00"; txtB.Select(txtB.Text.Length, 0); } } private bool TextIsValid(string myText) { var mn = new System.Text.RegularExpressions.Regex(@"^R\$ ?([1-9]{1}[\d]{0,2}(.[\d]{3})*(,[\d]{0,2})?|[1-9]{1} {0,}(,[\d]{0,2})?|0(,[\d]{0,2})?|(,[\d]{1,2})?)$"); if (mn.IsMatch(myText)) return true; else return false; } But, the strange thing is, in that code, in C#, the formating of text not work so fine than in the textbox, why ?
