    Hi,

    When using the C1TextBox control and I set it to only allow symbols, for example:

    C1TextBox.CharCategory = CharCategory.Symbol

    Why doesn’t it allow me to enter the minus sign “-”? It works fine for all other characters, except for the minus sign?

    Is there a way to configure it so that when CharCategory.Symbol is set, it also accepts the minus sign?

    Thank you in advance for your assistance!
