I'd like the ability to choose the behavior of mutli-row selection on a virtual grid with persisted selection.
For purpose of example, assume we have a virtual grid with 50 rows (pager controls not shown), a page size of 10, and persisted selection.
1. Select row 1 on page 1.
2. Scroll down to trigger page 2 to load (rows 11-20).
3. Select row 11, page 2.
4. Current Behavior: Both row 1 and row 11 remain selected.
5. Desired Behavior: Only row 11 remains selected.
Reasoning: I believe that a virtual scrolling grid should have selection behavior identical to a single page. That means that the only way to add rows to the selection is holding down control/shift during selection. In other words, on page 1 of the above example, if I select row 1, then row 2, only row 2 remains selected. If I select row 1, then Ctrl+click/Shift+click row 2, both remain selected. For virtual scrolling where multiple pages are displayed fluidly as if a single page, it seems odd to have the selection behave differently.
