I have found the following workaround to tinker with the info_dialog element before it is shown:

$(document).ready(function ()
{
    $.jgrid.jqModal = $.extend($.jgrid.jqModal || {}, {
        beforeOpen: centerInfoDialog
    });
});

function centerInfoDialog()
{
    var $infoDlg = $("#info_dialog");
    var $parentDiv = $infoDlg.parent();
    var dlgWidth = $infoDlg.width();
    var parentWidth = $parentDiv.width();

    $infoDlg[0].style.left = Math.round((parentWidth - dlgWidth) / 2) + "px";
}

I hope that helps

As I say you can not pass parameters to the modal. These are hardcoded.

Or maybe I can somehow scroll to the row in which the error occurs, so user cah see the dialog ?

Yes this is true. The dialog is shown in the row where the error is.

Currently there is no way to position the dialog in place where you want.

One possible solution is to pass parameters of the modal, but I need to chack this if this will not make other problems.

I'm using jqGrid in inline edit mode and I've implemented my custom function to check column value (on add and edit).

My grid is large, but fixed in height, so it has scroll.

When user enter invalid value warning dialog shows to the user, but at the very bottom of the page.

It seems it chooses the position to the row where invalid value is, but I'd like to position it at the center of the window.

How can I do it?

I know how to find it and position, but when?

Is there an event in which I can found this dialog via jQuery and position it?

Thanks
