Thanks for this. The id of every header check box is cb_jqg. But this point me that this a potencial bug when we use multiple grids with multiselect true. I recommend you not to use this id for now until I correct this in next release.
i also notice some problem. i am not sure if i am doing it in a proper way
i have the following in jqGrid to sync the select box with a column on db. however, when i change the num of rows it didn't work. changing the num of rows will not reload page from backend?
and the server should response no problem with different rowNum: value
it maybe a bug because when i change the rowlist say from 20 to 30. it work but just the select box sync function doesn't. however if i keep going and click next page or something else like fresh then works, 100%
also after i change the rowlist selection sometimes it work(i mean only the select sync) and sometimes it doesn't, sometimes when i change from 10 to 20. only the first 10 is selected and the rest are not. for sure if i click next/prev page it then work fine until i change the rowlist again.
