If ds_clients is a dataset, I'm not having a problem with that, Fred. My problem is in attempting to bind a control to an object property, and I think I've got it working for Combo's and TextBoxes:

Rule 1:

The property to which you are binding must be a public property, not a public field, not a protected or private property. This probably won't be an issue because the property will be a member of a business or UI services object and it'd have to be public anyway.

Rule 2:

For ComboBoxes, the binding must be done in the form's constructor. TextBoxes can be successfully bound in the Form_Load().
