Hi,

I'm trying to append a checkbox column to an existing grid/datasource (such that users can multi select via checking/unchecking). However, I'm having some problems.

I've attached a sample project. If you run it, you'll see that the checkbox column has been added correctly. Checking/unchecking different item works too. However, if you click on any one of the label header (sort), all the checkbox selections disappear.

 Another problem that I'm facing (on Windows XP) is that if you run the application without resizing the window, scroll all the way down with the mouse wheel, then scroll all the way up again, and (in my case) the scroll bar disappears.

Please help.

Thanks
