Hi,
I would like to allow only some pre-defined characters to be typed in a
TextBox (for example only integer numerical, or float numerical, or only
a set of letters and so on). How can this be achieved with Visual Studio
..NET 2005 (I am using C#) ? I found a PreviewKeyDown event for the
TextBox, but I dont see how to "block" the typing of certain characters.
Or is there some other way to get such a functionality ?
Thanks in advance for your help.
