I'm looking for a way to trigger a resize of a jqGrid by dragging the mouse.
Good news: in version 3.6 they've added a gridResize feature.
It adds the drag handle for you and everything.
jQuery("#grid")
.jqGrid('gridResize',
{minWidth:350, maxWidth:800, minHeight:80, maxHeight:350}
);
See the demo - it's the last item under "New in version 3.6"
