[CLOSED] Gridpanel with grouping feature , issues with group checkbox.
Hello ,
I have a Gridpanel with the grouping feature and checkbox selection model and I added a listener on the groupcheck to check/uncheck the rows of a group, but I have missing features that I want to implement :
- When I click on check all checkbox on the header, groups must be checked either.
- When I check all the rows of a certain group manually, the group checkbox must become checked and if i uncheck at least one row the group check box must become unchecked.
- Is there any way to prevent groups from collapsing when I check the groups?
