As a user, I would like to ability to pin one to many row(s) in a grid so that the pinned rows are always the first rows at the top of the grid.

If a filter is applied, the pinned records that match the filter should be displayed first.  Non matching rows may be hidden.

If a column sort is changed, the pinned rows should be sorted then the unpinned rows should be sorted to ensure the pinned rows are always at the top of the grid.  

As a developer, Pinning should be a optional feature configured when the grid is setup.

This essentially would only add a data populated "pin" column the user can toggle on or off, but the real effort in this request is around the sorting and filtering to ensure when the user clicks a column the event is captured, and the sort is submitted as pin column, then the selected column, to ensure the pin takes precedent.
