Hi Zebra,

Thank you very much! I tested the latest code you supplied. There is no leak anymore once I destroy the table.

But now by using your code, I find another issue. Once I called the “delRowData” method, I got the following error:

a(E, d).closest(“table.ui-jqgrid-btable”)[0] is undefined

Could you please help me find what's wrong with it?

Thanks again.
