Initial sort on page load
posted

I've tried to follow the example code, but my current result is that the sort field does get added to the GroupSettings area above the grid, but the grid is not grouped.   I can then drag the same column name up to the grouping area... the grid becomes grouped, but the grouping area shows the column header twice.

Any ideas or suggestions would certainly be appreciated.
