version 3.81

The children nodes will be deleted if the node collapsed, but cannot be expanded after click 'refresh' on navibar;

The children nodes will NOT be deleted if the node expanded, and also not be expand after refreshing grid.

v3.65 works ok.

hoping for this problem fixing.

In the grid.treegrid file : if(this[parent_id] == rc[$t.p.localReader.id]) 

$t.p.localReader.id, which has the value _id_. 

that's very strange, becouse when we use expandnode(rc),  we use getRowData to get the rc( the document said so).

But obviously, there is NO column's name is just to be "_id_". So all the method used the $t.p.localReader.id will return an undined.

I don't know what's  $t.p.localReader.id,  and I don't where it go to get it's value. But when I change the id column's name in my column model to "_id_", everything is just ok.

   var grid = jQuery("#list1");
                                    grid.delTreeNode(OLAPKey); 

Only the node is deleted, but all it's children node is left.
