Cetin,

I think what you are saying makes sense, very logical. But something does not work.

Here is how I test this:

I have the following line in a method of the BIZ class:

this.my_property = thisform.my_property

But I get error "Object is not contained in a Form." So it looks like even though I instantiate BIZ in the INIT method of the UI FORM and reference it to a property of the UI form, "thisform" cannot be references from BIZ class. What am I missing?
