Hi!

I have noticed that if jqGrid is inside a modal dialog (bootstrap modal in my case) position of the div.ui-jqgrid-resize-mark is wrong calculated when I'm trying to resize a column.

Here is my patch for jquery.jqGrid.src.js:

866,871c866

< this.curGboxParentOffset = this.curGbox.parents().filter(function() {

< // reduce to only relative position or "body" elements

< var $this = $(this);

< return $this.is('body') || $this.css('position') == 'relative';

< }).slice(0,1).offset();

< this.curGbox.css({display:"block",left:x.clientX-6-this.curGboxParentOffset.left,top:y[1],height:y[2]});

—

> this.curGbox.css({display:”block”,left:x.clientX-6,top:y[1],height:y[2]});

< this.curGbox.css({left:this.resizing.sOL+diff-this.curGboxParentOffset.left});

> this.curGbox.css({left:this.resizing.sOL+diff});
