Hello;
we try to migrate 8x to 9x but we had TreeGrid footer sum problem.
DHTMLX Snippet Tool 8.4.6 Pro it is works as expected
DHTMLX Snippet Tool 9.1.2 Pro it is not shows the footer summary in treegrid mode, but if you try grid mode it is works
did i missed something or it is a bug?
edit: in 9x, if collapsed: true , then sum not shows, if collapsed: false then sum shows. i think it is related to the collepsed feature and looks like a bug.
