formatted user control

I have written a usercontrol based on a textbox that will format and validate the data entered to the required set property, ie. Y2K date, long, decimal to two places, etc. It works well but has a serious flaw. The control uses the show,lostfocus and resize events to format and validate its data. However if I want to place a calculated value into the control from an action somewhere else none of the above events get called and I have raw data in the control. Is there a way to kick the usercontrol into realising that its data has been changed?.

Use the change event of the textbox or whatever control you are using.

I wish it were that simple. The CHANGE event monitors each keystroke and if you entering a date it will give an error immediately because you can't have a one letter date or if it is a numeric to two decimal places will immediately give 1.00 etc . What I need is a method for the control to recognise that a calculated value from another source is NOT coming from the keyboard and then format and validate it. With keyboard entry the ENTER key, lostfocus signify that data entry is complete.

That sounds like an interesting control.

create a new property, or use the text property to kick-off your validation routines.

I would choose the former, create a new property, and on the property let validate the data, that way you have an alternative method of loading the control, but with no validation (Text).  Call it "ValidText" or something.
