This currently causes the locked columns to not line up with the rest of the grid. See http://dojo.telerik.com/eZasA/2 and http://www.telerik.com/forums/column-locking-row-heights-not-matching#KsWBJy4lGkafpkwZxUYRVw
Hi Scott,
The Locked columns feature of the Grid relies on synchronizing the heights of the frozen and non-frozen part of the Grid. Changing the data in some of the cells after the Grid is rendered would override the synchronized row heights and will prevent the locked columns functionality to work as expected.
