Question

How can i add tooltip to my jqgrid header cells? in case of multiple grids in the same page.

This is my code:

var initialized = [false,false,false];
    $('#tabs').tabs
    (
        {
            show: function(event, ui)
                {
                    if(ui.index == 0 && !initialized[0])
                    {
                        init_confirm_payment();
                        initialized[0] = true;
                    }
                    else if(ui.index == 1 && !initialized[1])
                    {
                        init_signatory1_payment();
                        initialized[1] = true;
                    }
                    else if(ui.index == 2 && !initialized[2])
                    {
                        init_signatory2_payment();
                        initialized[2] = true;
                    }
                }
        }
    );



        function init_table1()
        {
            jQuery("#cpayment").jqGrid({
                url:'loadgrid.jsp?type=1',

Answer 1

Just include headertitles:true option in your jqGrid definition.

UPDATED: If you want set custom tooltip on a column header you can do following:

var setTooltipsOnColumnHeader = function (grid, iColumn, text) {
    var thd = jQuery("thead:first", grid[0].grid.hDiv)[0];
    jQuery("tr.ui-jqgrid-labels th:eq(" + iColumn + ")", thd).attr("title", text);
};

setTooltipsOnColumnHeader($("#list"), 1, "bla bla");

You should take in the consideration, that the column number iColumn is the 0-based absolute index of the column. Every from the options rownumbers:true, multiselect:true or subGrid:true include an additional column at the beginning, so the corresponding iColumn index should be increased.

UPDATED 2: For more information about the structure of dives, internal grid.hDiv elements and the classes used by jqGrid see this answer.
