Every remote virtualization demo show how to populate the grid but they all use oData.
Can someone help me figure out how to use standard JSON returned from my web service? I have attempted to modify this demo with no success: http://demos.shieldui.com/web/grid-virtualization/remote-data
The number, titles of the columns may be different per record, too... (see: ShieldUI Grid - Adding Columns at run-time)
