Mark,

Wierd is a synonym for grids. *s* Most of the complication in the code is dealing with the odd sequence of event firing inside the grid. You should be able to plug it in as the baseclass for your lowest level grid subclass instead of grid and mimimize the impact to your grids.

>I had a brief look at your class, and it looks great. It's fairly complicated (and weird:) but I'm sure it's the fastest way to accomplish the task. However, to use it, I have to integrate it into my own base grid class. Even on my P266, the DynamicXXX method is noticeably slow, so I expect I'll use your code.

>(Now, if someone could only tell me, just to satisfy my curiosity, why you'd set a Column's DynamicXXX property as if the grid were in scope and not the Column...)
