Cell is already in the collection

[Mark]

I can paste into a RadGridView no problem. But if I click on a column header to sort a row first, I get the following error on pasting:

System.ArgumentException: Cell is already in the collection
Parameter name: cellInfo

We're using version: 2012.1.215.1040

Hello,

 Thank you for contacting us.

I have tested the issue you have reported on this online demo. So far I was not able to get any problem when I pasted a cell value and then I sorted the column.

May I ask you to try using our latest binaries and let me know if the problem still remains?

I look forward to hearing from you.

Greetings,
Didie
