Thanks, I didn't think about that one. I have gone the route already of making each "sub-form" a user control, simply because it helps to encapsulate the functionality and the data. But I'm currently placing each user control (I'm up to about 10) on the form and handling sizing them all in the resize event, and toggling which one is visible based on user input. These user controls all fire events to let the form know what the user has done/requested. They each fire different events. Can I handle events like this if I create them dynamically?

>>If you had an area of the form that had to change depending on what the user selected in another area (The area could show customer lookup fields, it could show inventory tracking fields, it could show a list of reports to pic, etc...), would you make each one a custom control, put them all in that area of the form and just make one visible as needed? Or is there a better technique for that?
