Well, it manifests itself as erratic, not the first time around, but when the control gets the focus after e.cancel = true in a validating routine, or when focus is set programatically or when you select the control with the mouse. When you enter numeric characters it does not render what you enter. When I either "kill" the binding or comment our this routine, this erratic behaviour does not manifest itself.

I've googled . I've seen other people having similar albeit not identical problems. One MS guy suggested to add a textbox and bind that and leave the maskedtextbox unbound. Thought that to be somewhat overkill.

I used maskedtextbox because like the textbox in vfp it has a mask, and I'm kind of used the concept.

Thanks for caring.

PS: you're telling me that in C# you don't have that problem right? Could it be a VB problem, but it's been around for years, is it possible that they did not correct that "feature"? I know, I know, it is possible ....
