How can i get jqgrid frozen columns to work with word wrap on

The implementation of frozen columns in jqGrid are based on creating of two additional divs with absolute position over the standard grid. If the height of all column headers and all rows of the grid’s body are the same the frozen columns works good, but in case of variable height (usage of height: auto CSS) one have the following results (see the first demo):

The first div, so named fhDiv, which I marked with yellow color contains the copy of the column header (the hDiv) where the last non-frozen columns are removed. In the same way the second div, so named fbDiv, which I marked with red color contains the copy of the grid body (the bDiv) where the last non-frozen columns are removed. You can read here more about the standard grid elements.

In the demo I used character wrapping in the column headers which I described in the answer and the word wrapping described for example here.

The height of every row of the fhDiv or fbDiv will be calculated independent from the height of non-frozen columns. So the height of the rows can be less as required.

It is difficult to suggest perfect solution of the problem, but it seems that I found good enough pragmatical way. The idea is to set the height of every row from the fhDiv and fbDiv explicitly based on the size of the corresponding row in the main dives hDiv and bDiv. So I extended the code of fixPositionsOfFrozenDivs function described in the answer to the following:

var fixPositionsOfFrozenDivs = function () {
        var $rows;
        if (typeof this.grid.fbDiv !== "undefined") {
            $rows = $('>div>table.ui-jqgrid-btable>tbody>tr', this.grid.bDiv);
            $('>table.ui-jqgrid-btable>tbody>tr', this.grid.fbDiv).each(function (i) {
                var rowHight = $($rows[i]).height(), rowHightFrozen = $(this).height();
                if ($(this).hasClass("jqgrow")) {
                    $(this).height(rowHight);
                    rowHightFrozen = $(this).height();
                    if (rowHight !== rowHightFrozen) {
                        $(this).height(rowHight + (rowHight - rowHightFrozen));
                    }
                }
            });
            $(this.grid.fbDiv).height(this.grid.bDiv.clientHeight);
            $(this.grid.fbDiv).css($(this.grid.bDiv).position());
        }
        if (typeof this.grid.fhDiv !== "undefined") {
            $rows = $('>div>table.ui-jqgrid-htable>thead>tr', this.grid.hDiv);
            $('>table.ui-jqgrid-htable>thead>tr', this.grid.fhDiv).each(function (i) {
                var rowHight = $($rows[i]).height(), rowHightFrozen = $(this).height();
                $(this).height(rowHight);
                rowHightFrozen = $(this).height();
                if (rowHight !== rowHightFrozen) {
                    $(this).height(rowHight + (rowHight - rowHightFrozen));
                }
            });
            $(this.grid.fhDiv).height(this.grid.hDiv.clientHeight);
            $(this.grid.fhDiv).css($(this.grid.hDiv).position());
        }
    };

I called the method inside of resizeStop and loadComplete callbacks. In case of usage of gridResize method one need include additional fixes inside of stop handler.

The full my suggestions you can see on the demo which fixs the results from the first demo to the following:
