I have a big application with many textbox controls (about 300-400).
I need to forbid an unicode input for all the textboxes. Is there any easy way to do that ?
C#, VS 2008, .NET 2.0
Maybe there’s some global application handler or something else ?
Edit: I want to allow an input of latin alphabet symbols and digits. Chinese, japanese, and other alphabets must be prohibited.
Create a custom control that encapsulates the TextBox, or simpler a class that inherits from TextBox, and in either case suppress the characters you don’t want. Replace all instances of System.Windows.Forms.TextBox (and TextBox if there are any) with YourCustomClassName.
