Listgrid GroupTree openAll not working as expected ?

[san1001_99]

Hi,

I see that Listgrid.getGroupTree().openAll() does not result in the opening of the grouped rows. Is there any other way to achieve opening all grouped rows in a listgrid ?

Thanks.

when openAll is called the children are presented but folder childern doesn't have the 'plus' sign, the user isn't able to open the children folder.

Any idea?

listGrid.groupStartOpen controls which groups are initially open - use this property instead of a manual call to openAll(). The problem you're seeing is most likely caused by calling openAll() at an inappropriate time (eg, group tree has not been formed yet).

Hello Isomorphic,

I'm facing a similar issue today where I'm calling listGrid.getGroupTree().openAll(). It works at one place in my code, but doesn't work at other.

So, it does seem to be a timing issue like you mentioned. You said "group tree has not been formed yet". Is there an event that I can look for to check that the group tree has formed?

Thanks for your help.

Here's my code which doesn't work. I thought it would work when user manually selects the "Group by" option from the Header Context Menu on a particular field in the list grid.

        listGrid.addGroupByHandler(new GroupByHandler() {
            
            public void onGroupBy(GroupByEvent event) {             
                
                Tree tree = listGrid.getGroupTree();

                if (tree != null)
                {       
                    tree.openAll();                       
                }
            }
        });
