Keeping text selection in DataGird while scrolling
I am using RichEditableText for an item renderer. The selected text in a
cell will get unselected after the row with selected text goes out the
view. How can I keep text selection for all time?
Thanks

itemrenderer has a data property which is the model, in where you should
keep text selected status, but only triger update in renderer to have great
performance, if you really bind text selection(the view)to data, it will
work.
I have concrete example if I am allow to post link here.

Is there a way of not using virtual renderers? Just want to see what kind
of performance I am going to get.

It will be a trade-off of the cost of doing that vs not having virtual
renderers.

But in order to re-highlight text I need to keep selection info somewhere
to reapply it or just apply it. Is that the direction to take?

If you are using virtual renderers then you need to re-highlight text when
the renderer is updated.
There are options about showing selection when inactive that you may need
to use.
