Memory Leak in IE8

[yucheng.qianParticipant]

Hi,

“destroy” method doesn’t release the memory of the grid in IE8. Repeatedly creating and destroying grids in IE8 make the memory used keep increasing. I’m using v2.8.3 and the following code to test. When running the code, the memory of the IE8 process in Windows Task Manager keeps growing without ever decreasing. However, the code in IE10 seems to be working well: the memory keeps at a low level and doesn’t increase (or increasing very very slowly). Could you please advise how to fix the memory leak in IE8? Thanks!

Hi,

Unfortunately, that version of the browser has problems with its garbage collection. We cannot help about that. All Elements used by the Grid are removed after calling “destroy”.
