Hi there,
in my case i solved this by adding an image to the button with a fixed id, and then getting the button via jquery…
//in grid, when creating the button
...
renderstatusbar: function (statusbar) {
// appends buttons to the status bar.
var container = $("<div style='overflow: hidden; position: relative; margin: 5px;'></div>");
var addButton = $("<div style='float: left; margin-left: 5px;'><img id='<strong>popgridadd</strong>' style='position: relative; margin-top: 2px;' src='/scripts/img/add.png'/></div>");
container.append(addButton);
//on event
...
$("#popgridadd").parent().jqxButton({ disabled: true });
