I have a (razor) Grid with two groups added:
   .Group(groups => groups.Add(dd => dd.grp1))
   .Group(groups => groups.Add(dd => dd.grp2)

I have been able to find examples to collapse ALL groups, but am wondering how to get a handle to just grp2 so that is the only one collapsed?
The data in grp2 can be a variety of random numbers , so something like below will not work for me:
    grid.collapseGroup(".k-grouping-row:contains(Beverage)");

Thanks in advance for your response.

Hello Peggy,

The group field (or it's title if set) is also part of the grouping row text, so you could use it in the :contains() selector instead of the field value.
E.g.

grid.collapseGroup(".k-grouping-row:contains(grp2)");

Thanks for the quick reply, unfortunately, I still haven't gotten this to work. I've attached my example. Can you take a look and let me know what I am doing wrong?
Thanks so much!

Hello Peggy,

Please excuse me for the inconvenience. You could use the following approach a pass the group rows one by one to the collapseGroup method.
E.g.

function dataBound(e) {
    var grid = $("#grid").data("kendoGrid");
    $(".k-grouping-row:contains(Discontinued)").each(function () {
        grid.collapseGroup(this);
    });
}
