Decimal point is comma on numeric keypad

Hello Frits,
You are right, most likely, you'll have to customize some controls in your application individually, to apply this solution. However, please note that it is enough to set the culture settings, such as NumberDecimalSeparator, only once, when the application is started, as shown in the following code:

C#
CultureInfo culture = new CultureInfo(System.Threading.Thread.CurrentThread.CurrentCulture.Name, true);  
culture.NumberFormat.NumberDecimalSeparator = ",";  
System.Threading.Thread.CurrentThread.CurrentCulture = culture;  

Please let me know if you need any further help.
Thanks,
Anatol

Hi Anatol,
I found a workaround that works for me.
In the attached sample I did the following:
     Create a form called <Basis> which inherits from
          public partial class Basis : DevExpress.XtraEditors.XtraForm
     In design of the form basis set the option KeyPreview to true
     Make a event on KeyDown
          private void Basis_KeyDown(object sender, KeyEventArgs e)
          {
               if (e.KeyData == Keys.Decimal)
               {
                    e.SuppressKeyPress = true;
                    SendKeys.Send(",");
               }
          }
     The MDI-Children inherits
      public partial class Form1 : Basis
Now the decimal key on the numeric keyboard gives always a , instead of a . character.
It works on a textbox and on a gridview.
Is there any reason why I shouldn’t implement this in my application.
With regards,
Frits van Ooijen

Hello Frits,
I've tested your solution, and found only one situation when it doesn't work: with this design, our MaskManager cannot correctly handle the decimal separator pressing, and you are able to make two decimal separators within a single field. As a result, the validation error will occur when you try to leave the field. I don't know whether it is a serious problem for you.
I should also add that with my culture settings (en-us), it is still required to change the NumberDecimalSeparator property, to make this solution work.
Thanks,
Anatol
