call default sort func in my customSortFunc
posted

Hi experts,

I'm using customSortFunction here, http://www.igniteui.com/help/api/2013.2/ui.iggridsorting#options:customSortFunction, but I dont want to write everything. Is there a way to call it's default sort function?  Say my grid datasource is a array of student object, each student has id, name, ***. And for student whose id equals to 1, no matter which column is sorted, the student 1 always stay on top of the grid. What come to my mind is check whether obj's id is 1, if it's 1, when asc, return -1, when desc, return 1. And for students whose id are not 1, I want to call default sort function. But I don't see a way to call the default sort func. Please help!
