Feature of "certain part of view or cells don't need to be re-rendered"

It would be great if Grid can provide an interface that is saying "certain part of view or certain cells don't need to be re-rendered".

We came across this when implementing indirect selection(please see the attachment "grid_multiple_checkboxes.jpg"), the first column with checkboxes will be flashed once or more times(should equal the rendering time) when columns are resized or moved, the reason is checkboxes need more time for rendering, and in this case the column of checkboxes doesn't need to be re-rendered.

I think this can also improve the performance in some situations.
