TreeGrid: Expand to Node?

Suite and Optimus Suite 5
#1

Given a fully-loaded treegrid structure, is there a function which will open all the nodes from a parent node to a given descendant?



For instance, given the following tree structure:

Node 1

|- Node 2

| |- Node 3

| - Node 4

| - Node 5

-Node 6

- Node 7



What we are looking for is a function which could accept an input of “Node 4” (or it’s id, really) and expand Node 1 and Node 2, leaving Node 6 collapsed (and, ideally, allowing a parameter to determine whether Node 4 itself should be expanded or not to show Node 5.)



We could create a custom function which discovers the parent and recurses up through the tree, but wanted to make sure there wasn’t anything like that already written.



Thanks,

If you are using treeGrid  in normal mode ( not dynamic loading one ) the
    grid.openItem(id)
works exactly as necessary in your case , it expands all parent branches from top to necessary item

to show item 4 in expanded state
grid.openItem(4)


to show item 4 in collapsed state
grid.openItem(4);
grid.closeItem(4);

That works like a charm. Thanks!
