Print Page - How can I keep treegrid's expand state when reload date?

You will need to save the treegrid options data then restore the data afterwards.

Here is what I use (with a session helper function):

Code:

        dg.datagrid({
            onClickRow: function() {
                // Save current selection and options
                Session.set('dataSelected', $(this).datagrid('getSelected').id);
                Session.set('dataOptions', $(this).datagrid('options'));
                Session.set('restoreData', true);
            }
         });

Restore

Code:

        var opts = Session.get('dataOptions');
        var id = Session.get('dataSelected');
        var restore = Session.get('restoreData');
        
        if (opts && restore) {
            dg.datagrid({
                sortName: opts.sortName,
                sortOrder: opts.sortOrder,
                pageSize: opts.pageSize,
                pageNumber: opts.pageNumber
            });

            dg.datagrid('selectRecord', id);
        }
