Expanding group

[hfParticipant]

Hi,

I would like to expand a group based on a userid, but don’t know how determine which group number I’ve to get:

function groupsrenderer(defaultText, group, state, params) {
user = params.subItems[0].user;
if (params.subItems[0].user == userid) {
                    $("#jqxgrid").jqxGrid('expandgroup', ????);
                };
};

Regards

Hi hf,

It is not possible to expand a Group in a groups rendering function. The “expandgroup” method can expand only top-level groups and the
expected parameter is the row’s index.

Hi Peter,

Okay, but in de grid’s ready function it will work. So I would like to save the correct groupnr in the groups rendering function and apply in the grid’s ready function.

But I don’t know how to get that groupnr..

function groupsrenderer(defaultText, group, state, params) {
                var user = params.subItems[0].user
                if (params.subItems[0].chef == 3) {
                    groupnr = ???;
                };
                return "<div style='margin: 5px;'>" + x + "</div>";
            };
ready: function () {
                    $("#jqxgrid").jqxGrid('hidecolumn', 'whatever');
                    
                    addfilter();
                    $("#jqxgrid").jqxGrid('expandgroup', groupnr);
                },

Hi hf,

You cannot expand a group when you render it in the “groupsrenderer”. You also cannot expand a group through the API unless it is a root group. In addition “groupsrenderer” is called when the group becomes visible and have to be rendered. If the group is not part of your view and is still not rendered your logic for saving a group will not work. You can call “expandgroup” and pass index of the group in the “ready” callback or in the “bindingcomplete” event handler.
