I have a jqgrid with pager buttons that I want to customize and I would like to keep the buttons (next, forward, first and last) from being disabled once the grid is binded
If you need to have the "Next" and the "Last" buttons of the pager enabled just because you don't know the number of records and the number of pages which you has you can do following:
total value at least one higher as the current requested page. For example: "page":1, "total":2.pgtext and recordtext options of jqGrid (see the documentation). For example pgtext : "Page {0} of ..." and recordtext: "View {0} - {1} of ..." or just pgtext : "Page {0}" and recordtext: "View {0} - {1}"
