Sorting issue in Grouping SlickGrid

[ManasaReddy4]

Here is the code I am using for a grouping slick grid. The issue is sorting does not work properly as posted in the examples section. As per the example, Slickgrid prevents sorting for group titles. This is the behaviour which I need. But in my version when you sort the columns, the groups get sorted also.

you need to use the comparer function . first sort the column by which u r grouping then by other columns. See here: http://stackoverflow.com/questions/15659653/slickgrid-exclude-slick-group-group-header-row-when-sorting
