jqGrid error when setting width using new API

I'm using the new API to set the width of my jqGrid like this:

$('#grid').jqGrid('setGridWidth', $(window).width() * 0.98);

The problem is that in IE7 I'm getting this error:

'p.cellLayout' is null or not an object

This only happens in IE7 (IE8, Firefox and C开发者_JAVA技巧hrome work fine). Has anybody else encounter this problem and fixed it?

Probably you try to use setGridWidth function on the wrong place. I would recommend you to place this call inside of loadComplete or gridComplete event.

UPDATED: I have no IE7, so I can not test this problem. There are parameter cellLayout of jqGrid which has default value 5 and is documented on http://www.trirand.com/jqgridwiki/doku.php?id=wiki:options. This parameter are used inside of setGridWidth function. If is not clear you me why this parameter should be null, but you can verify this before calling of setGridWidth. The construct alert($('#grid')[0].p.cellLayout); will show you this value. You can try to set this value to 5 before calling of setGridWidth, but if you really have this property as null, you have definitively a problem somewhere else.

In all situations like your problem it is always good to post a code example in your question, so that other could reproduce your problem. Sometimes you have a real problem not on the place which you describe. So a code example is always very helpful.
