>>Hi everybody,

>>We have textboxes on different forms, which seem to exibit the same strange behavior. The textboxes are unbound, have $ as format and 9,999,999.99 in InputMask (set in design time). Now, if you press the Enter, the cursor moves to the next control. You go back to that textbox and press Enter again and one of the digit disappers. In other words, each time you go back to the control and press Enter, one of the digits will vanish.

this.AddProperty('nTextValue',0)
>this.ControlSource="this.nTextValue"

I see. It would not give any impact, right? And you don't have to use this fake controlsource.

I don't want to do it on a textbox class level, but will do for the forms in question.

BTW, do you have a thread reference?
