Hi,

I would like to raise "exception" in Property Setter method. For example, upon user specify value to textbox and updated to field property, my program will check for some logic, if not valid, I want to show error provider icon immediately instead of waiting Save().



I tried to add broken rules, but it doesn't reflect the UI.



How to raise the "event" so that error provider icon will be shown?



Thank you

Most grids have a DataError event that will be raised when an exception occurs.  The grid will trap the exception and raise the event and pass the exception through the event args.  This would allow you to show a message box or set the text on a label somewhere that would indicate the error to the user.  However, as I mentioned in your other post about this similar matter, you'll need to add the broken rules to the BBS.BusinessObject reference for the ErrorProvider to pick up the error and display it.
