jqGrid multiselect gives only ids when top checkbox has been checked?

Question

I have a jqGrid with multiselect:true. In a click event of a button I try to retrieve the ids like:

var ids = $('#myGrid').jqGrid('getGridParam', 'selarrrow');

However I only get ids to be filled with something if I select the top checkbox in the header. If I do not select that one in the header but select several checkboxes in the column ids has no selected ids in it. How to overcome this?

sellarrrow is according to this example written correctly: http://www.trirand.com/blog/jqgrid/jqgrid.html, select Advanced, Multiselect example.

Answer 1

Turned out to be a defaulting setup where this was set:

beforeSelectRow: function(rowid, e) { return false; },

Setting that to true gave me back the power.
