Does anyone know how to bind a control's property to the opposite (not) of a boolean data object's property? So, something like

textbox.DataBindings.Add("Visible",myEmployeeEntity,Not(IsEmployeeMarried))

In this case, I want the textbox to be visible when the myEmployeeEntity.IsEmployeeMarried is false.

Right now I have to create a property called IsEmployeeNotMarried to bind to...

Is it not possible to just set the textbox.Visible = !myEmployeeEntity.IsEmployeeMarried

Thats pretty much what I ended up doing. But I had to catch the change events from the entity to refresh the control...something I was hoping binding would do..

Could you hook into the databinding format event and possiblying convert the result there??

Control.DataBindings[x].Format

Dont qoute me on the above, as i am going off the top of my head

Thats a good idea, I'll try that. Thanks

Another idea, is to add a read-only property to the generated entity class with a getter only, to return the negation of the IsMarried property (eg. IsSingle which returns !IsMarried)

And use this new property in the databinding.
