Rene:

What is a framework? Here is one explanation:
"An application framework is a set of reusable components with a reusable application design. This means that you not only get a lot of functional code but you also start with a design of how they work together. This means that an application framework can provide far more functionality that a library of functions as these are basically independent of each other." Maurice De Beijer

Here are a couple of recent threads: 1034435, 1039251

There are a number of commercial frameworks (I use Mere Mortals Frameworks) and some freebies

The Mere Mortals .Net framework has the "AddRowsWithDownArrow" property that can be set to false to stop users adding new rows.

Hope that helps
