Loading Message inside ScrollTemplate? .......
While I was testing, I notice that the ScrollTemplate is a full container for the grid (except panels??) , so it can help us in some situations.
But is it the right place to store a Loading msg <span> ?? (could be)
I made a paging & sorting sample based on Sudhaker post:
http://www.activewidgets.com/javascript.forum.19163.6/record-level-editing-using-popup.html
Also splash by sorting in different color :-)
