Hi all.
There's a small error on Samba.Presentation.Common.FilteredTextBox.cs
On OnPreviewTextInput you define ds (decimal separator) as
var ds = CultureInfo.CurrentUICulture.NumberFormat.NumberDecimalSeparator[0];
It might be
var ds = CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator[0];
because of possible different values.
An example, Peru.
CurrentUICulture=es
CurrentCulture=es-PE
decimal separator es => , (comma)
decimal separator es-PE => . (dot)
so if you use CurrentUICulture is not possible at all input decimal values in number fields.
