Well it did fix the ad hoc problem, but I was hoping the handle this in the baseclass whereas now I have to worry about it at the form level and the code ain't pretty :) :

        Me.BindingSource1(0)("Art_Snijden") = IIf(Me.ARt_SnijdenCtl.Text = "Ja", True, False)
        Me.BindingSource1(0)("Art_Korting") = IIf(Me.Art_KortingCtl.Text = "Ja", True, False)
        Me.BindingSource1(0)("Art_Uitzonderlijk") = IIf(Me.art_Uitzonderlijkctl.Text = "Ja", True, False)
        Me.BindingSource1(0)("Art_VerwittigenGewicht") = IIf(Me.Art_VerwittigenGewichtCtl.Text = "Ja", True, False)
        Me.BindingSource1(0)("Art_Perpersoon") = IIf(Me.Art_PerpersoonCtl.Text = "Ja", True, False)

btw when I issue these statements? the parse event is fired, you would expect the reverse no? I'm probably missing something major here.

>>>More likely what is happening is that you're clicking on a MenuItem or ToolBar button ...these controls do not cause the ActiveControl to lose focus, thus not forcing the control's value into it's databound object, which is when the Parse event fires. You need something that will force this for every control you have (it's the Validated event that accomplishes this). It can get complicated.

>>>I have a method that I have named ForceBind() in most of my controls (those that have it implement an Interface I have created for this type of behavior). If the control is a container object that implements that Interface (such as a Panel, UserControl, etc.) it will call the ForceBind() method of *it's* ActiveControl (if *that* control implements the Interface).

I'm not sure if this is your problem, Marc, but it certainly could be. Let me write something up for my blog and I'll post the link here once it's done.
