Hi Patrick,

Generally speaking, yes, but it depends on the feature:

for example, you can get the state of sorted columns by checking:

$("#grid1").igGridSorting("option", "columnSettings")

(you can apply it on the http://samples.infragistics.com/jquery/grid/sorting-column-settings sample)

This will give you a JSON of the state of each column (whether it's sorted, if it is, is what direction and so on).

selected grouping

$("#grid1").igGridGroupBy("groupByColumns");

(usable on http://samples.infragistics.com/jquery/grid/enable-groupby-feature)

Hidden columns are trickier - there's a "hidden" flag for each column so you have to retrieve the grid's columns like so:

$("#grid1").igGrid("option", "columns");
//The 'hidden' flag for the 1st column
$("#grid1").igGrid("option", "columns")[0].hidden

(usable on the sample http://samples.infragistics.com/jquery/grid/column-hiding-on-initialization) 

All results will be in JSON format so there shouldn't be need to serialize them further.

However, if you need anything else in specific, please let us know.

Cheers,
Borislav
