jqGrid programmatically navigating to the next/previous row

When I have a currently selected row in my jqgrid, and I have buttons that say "Next" and "Previous", how do I programmatically do that? Upon initial investigation, I'll need to get the ids of the rows but is there a way to do this by just using the index of the curre开发者_开发知识库nt selected row in the grid?

The ids in my rows are not sequential and are of random values.

Thanks

$('#btnNext').click(function () {

  var grid =  $("#grid").jqGrid({...});

  var selectedRow = grid.getGridParam('selrow');
  if (selectedRow == null) return;

  var ids = grid.getDataIDs();
  var index = grid.getInd(selectedRow);

  if (ids.length < 2) return;

  index++;

  if (index > ids.length)
    index = 1;

  grid.setSelection(ids[index - 1], true);

});

According to http://www.trirand.com/jqgridwiki/doku.php?id=wiki:events, there's row index property but it doesn't get passed in to onSelectRow event. Perhaps you could get to the row object via its ID and check whether it has a row index, possibly called iRow. From there you'll just have to find the next row by row index iRow+1.

var rowId;
var previousRecord = false;
var array;

function initGrid() {

    array = $(ProspectsGrid).jqGrid('getDataIDs');

    var i = 0;

    if (previousRecord == true)
        i = array.length-1;



    $(ProspectsGrid).setSelection(array[i]);

    rowId = array[i];

}


function GetNextRecord() {



    previousRecord = false;

    if (rowId != array[array.length - 1]) {
        var i = 0;
        while (rowId != array[i]) {
            i++;

        }
        i++;
        $(ProspectsGrid).setSelection(array[i]);
        rowId = array[i];
    }
    else {

        var currentPage = ProspectsGrid.getGridParam("page");
        if (currentPage < ProspectsGrid.getGridParam("lastpage")) {
            ProspectsGrid.setGridParam({
                page: currentPage + 1

            });
            ProspectsGrid.trigger("reloadGrid");
        }
    }
}

function GetPreviousRecord() {
    previousRecord = true;
    if (rowId != array[0]) {



        var i = 0;
        while (rowId != array[i]) {
            i++;

        }
        i--;
        $(ProspectsGrid).setSelection(array[i]);
        rowId = array[i];
    }
    else {
        var currentPage = ProspectsGrid.getGridParam("page");
        if (currentPage > 1) {
            ProspectsGrid.setGridParam({
                page: currentPage - 1

            });
            ProspectsGrid.trigger("reloadGrid");
        }
    }
