I ran across an issue when mass rendering local data with options: { datatype: “local”, gridview: true }. The issue turns out to be line 1598 in method addJSONData. The following original line uses the global jquery selector instead of a scoped selector

$(“#” + $.jgrid.jqID(ts.p.id) + ” tbody:first”).append(rowData.join(''));

I changed the line to the following and was able to mass render the rows without being attached to the dom.

$(“tbody:first”, t).append(rowData.join(''));

The issue mainly came up with native Windows XP IE8 Standards as a relatively big performance hit.

I am using jqgrid version 4.1.1

Just FYI, keep up the good work!
