    Hi all,

    I tried out this demo to be able to drag rows inside of a grid: http://demos.telerik.com/kendo-ui/sortable/integration-grid

    It works great unless the following line is added in javascript:

    kendo.ns = "kendo-";

    If "kendo.ns is" set than you can only change 1 row before the console prints this error: "Uncaught TypeError: Cannot read property 'uid' of undefined". And you can no longer drag any row after that one time.

    Here is an example: http://dojo.telerik.com/oPanI

    Our project doesn't allow for this line to be removed, is there still a way to keep this drag functionality somehow?

    Hello Bert,

    The error is caused by the fact that the demo code is accessing a data attribute. When the kendo.ns is set, the data attributes rendered by the widgets will be prefixed with the value of the kendo.ns, thus this code will not work. You should instead modify the code to access the attribute using the correct prefix:

    dataItem = grid.dataSource.getByUid(e.item.attr(kendo.attr("uid")));
