Bonnie,

Thanks for this great start! (It does depend on overriding some custom event handlers in your TextBox subclass, but I can cope with that as soon as I study up some more on binding. I've been using Mere Mortals and haven't had to worry much about that yet.) One thing it has that the other solutions I've looked at lack (including the NumericUpDown control) is that it won't allow entry of two decimal points or two minus signs. (Duh!) The only thing it needs is checking for the number of digits entered after the decimal.

I am hoping that the 3.0 framework has some features that makes things like this a bit easier "out of the box"! While I like the flexibility the framework gives us, I still believe the it should give a novice this kind of functionality without hours (days?) of programming.

>I haven't used hardly any of the new features of 2.0 yet, so I decided to look at the new MaskedTextBox. Wow ... what a useless piece of garbage ... at least for decimal data, I didn't try using it for anything else just yet. There may be tricks one has to know to get it working correctly, but I haven't researched it at all.

I don't know for sure though, so test this out just sub-classing from the .NET textbox and if it still doesn't do it correctly, let me know and I can post the code for our TextBox class.
