TypeError: Cannot read property ‘visiblerecords’ of null [http://localhost:53094/jqwidgets/jqxgrid.js:7]

I get this error, with my grid.
Everything seems to be working as it should, but I hate having javascript errors.
Any ideas why I get this? Any ideas to how I get rid of it?

Alright, this is my gridview.

I have played around with it a bit, and if I remove width: ‘100%’, the error goes away.

function InitGridView() {
    $("#jqxgrid").jqxGrid(
{
    autoheight: true,
    theme: 'lpstore',
    columnsresize: true,
    pagesizeoptions: ['10', '25', '50', '100'],
    pagesize: 25,
    width: '100%',
    altrows: true,
    sortable: true,
    pageable: true,
    localization: getLocalization(),
    autorowheight: true,
    columns: [
        { text: '', datafield: 'typeid', cellsrenderer: imgConverter, width: 32 },
        { text: 'perlp', datafield: 'IskPerLp', cellsalign: 'right', cellsformat: 'd2' },
        { text: 'Item', datafield: 'typename', cellsrenderer: multiLineRenderer, width: 300 },
        { text: 'Investment', datafield: 'TotalCost', cellsalign: 'right', cellsformat: 'd2' },
        { text: 'Return', datafield: 'TotalReturn', cellsalign: 'right', cellsformat: 'd2' },
        { text: 'Profit', datafield: 'TotalProfit', cellsalign: 'right', cellsformat: 'd2' },
        { text: 'Sell orders', datafield: 'volume', cellsalign: 'right', width: 100 }
    ]
});
    
}

I don’t really know how to reproduce. To be honest, I don’t know when this error started occuring. I’m pretty sure it wasn’t always there.

Anyhow, I have uploaded my site, so maybe that’s the best way to see it?

http://www.lpbeta.noonecares.dk/LpStore/Corporation/Court%20Chamberlain

This is the direct link to the page where I use the gridview.
Sorry for being a little vague, I just don’t really know how to explain it.

Maybe I should have mentioned, that all the grid code is in “/Scripts/Corporation.js” 🙂

Hi,

I am not sure what could be wrong in that page. I also could not find which version you use as the header information about the version seems to be removed. In case you do not use the latest version – 2.9.2, I suggest you to upgrade to it.

Aha, I think I have solved it.
It seems to be due to me creating the grid, and setting the width, BEFORE adding any data to it.

I have changed my init code, to take in the dataadapter, and set it right away, and now it works!

Peter, yea the ASP.NET MVC framework I’m developing in, has this neat bundle function, where it bundles up all the js files.
I guess it removes all the comments, and minimizes it even more.

It is 2.9.2 I am using 🙂

I have to say, you guys have an amazing product and amazing support.

Thanks to all of you. And sorry for being vague.
