>>>There is also third approach to it, like it is done in VFX framework . There is a grid subcass and a Grid Builder where you just select if the columns should be sorted, and the Grid Builder writes the OnSort() method call into each Header.DblClick(). The indexes a built on the fly and destroyed when necessary by ClearAllidx() method.

That doesn't sound too hard. :)
