Grid pukes when click sort and click drag a column

[Ryan]

Hello,
I am currently using the newest Q3 telerik release. I have a grid which utilizes the RadAjaxLoadingPanel. The following steps raise a javascript error.  

1. Click on a column header to sort.
2. As the column is sorting click again and hold.
3. Drag the column while holding as to move the column to a new location or order.

I recieve the following javascript error:
"this.get_element()' is null or not an object" on line number 124

Do you have any suggestions on what could be causing this error?
Thanks for any input.

Hello Ryan,

I was able to replicate the error on this online demo of the product, however, note that reordering the columns in the grid during ajax request execution (when it is not completed) is not appropriate and can generate errors/cause unexpected results.

To avoid that, consider disabling the grid when the ajax request is triggered and re-enable it again when it is completed:

or simulate modal loading image as demonstrates in this code library entry:
