Mya,

>how can i change Grid Column Header Size dynamically by using View Property "3. Change Change"?

I don't believe you can change the amount of space the headers consume in a change/change grid.

Can you better explain what you are trying to accomplish? You may be able to achieve what you are wanting to do by using a normal grid with a single column that contains a container class which has controls for each of the fields in the table.
