Subgrid inside another subgrid visual issues

Hello.
Grid version is 2.0 build 81009 but tried with 2.5 build 91111 with a very similar results.
Here is the problem.
I have a grid with 4 levels of subgrids.
Opening a row in the topmost level - the subgrid of the second level is loading. The height of the row of the topmost grid is increasing to fully contain the opened subgrid.
Then in this subgrid trying to open a row to get a subgrid of the 3-rd level. It is opening but the height of the row of the topmost grid is not increasing so overlapping of different subgrid levels appearing.
Please advise.

Try to attach following code to your page:

subGridLevel2.attachEvent("onSubGridLoaded",function(){ subGridLevel1.setSizes(); })

If issue still occurs please open ticket at support.dhtmlx.com/ and provide us complete example where we can reproduce it.

Unfortunately this didn’t help.
But maybe you can advise how to get the parent grid from inside the function onSubGridLoaded?
It may help me in this situation.

If you have not found an issue, this worked for me:

            primary_grid.attachEvent("onSubGridLoaded",function(subgrid){
                subgrid.setSizes();
                subgrid.callEvent("onGridReconstructed",[]);
                subgrid.attachEvent("onSubGridLoaded",function(subgrid2){
                    subgrid2.setSizes();
                    subgrid2.callEvent("onGridReconstructed",[]);
                    subgrid2.attachEvent("onSubGridLoaded",function(subgrid3){
                        subgrid3.setSizes();
                        subgrid3.callEvent("onGridReconstructed",[]);
                        subgrid3.attachEvent("onSubGridLoaded",function(subgrid4){
                            subgrid4.setSizes();
                            subgrid4.callEvent("onGridReconstructed",[]);
                            ready();
                            return true;
                        });
                        ready();
                        return true;
                    });
                    ready();
                    return true;
                });
                ready();
                return true;
            });

That let’s me go down four subgrid levels without the primary row height issue.

This solution fix my problem. Tks!
