Hello,
I've put WebHierarchicalDataGrid inside UpdatePanel, and faced with the following problem:
1. First time page's successfully loaded and all works fine
2. After very first postback I get javascript null-reference exception:
$find(gridId).get_gridView().get_behaviors().get_selection() returns null, but without UpdatePanel all works fine.
Property EnableAjax for the grid is off, because it causes other problems.
Please help.
Alexander
Hi,
I've figured out the problem. It was my mistake, I cashed grid object on the client side, it caused the problem after async. postback.
Sorry for inconvenience.
