Hello,

This is corrected in 3.6.5. Also we introduce a new parameter - deepempty - see what is new.

Regards

Tony

I've been looking into this for hours, one interesting thing ive found is that the DOM elements that are left lying around are <TR> and <TD> elements with no parent. Does anyone know of a manual way of deleting these? I can't seem to access them in javascript, but the sieve tool shows that they're still hanging around (and build up each time i switch pages)

Oh, i forgot to add this (it might help) ...

function getData(postdata) {

    $.ajax({
        type: "POST",
        url: dataURL,
        data: JSON.stringify(postdata),
        dataType: "json",
        contentType: "application/json; charset=utf-8",

        success: loadGrid,
        error: function() { alert('error'); }
    });
}

function loadGrid(jsondata) {
var thegrid = $(gridName)[0];
thegrid.addJSONData(jsondata.d);
}

Hi All,

First i just want to say that I love jqgrid - ive been using it for a few weeks now and think its awesome 🙂

I'm trying to make a large web application, and have hit a wall in regards to memory leaks. I find that my browser chews up memory quite alot.

As an example, I have a simple page with a jqgrid in it with paging enabled. Using sieve, i find that when i switch from page 1 to 2, then back to 2, and keep doing that, then rows are not released from memory and the DOM count just keeps building.

I'm using a function for the grid's datatype, which gets the data using AJAX and uses thegrid.addJSONData(). Could this be the problem.

Has anyone else had these sorts of issues? Its driving me nuts 🙂

Cheers,

Michael
