View Full Version : Load children of node in Treegrid as expanded by default

21 Mar 2014, 5:06 PM
Dear community,

I am loading the children of a specific node in a TreeGrid using:

gridStore.load({node: parentNode});
(each child can have children, which means I am actually loading subtrees)

The problem:
Allthough all nodes have properties:
{..., "leaf":false,"expanded":true,"loaded":true}

the are all collapsed by default, but I want them to be all expanded.

Edit: Just one thing to add, I have to click on the [-] of the loaded node to make it expand.

Any ideas?
Thank you in advance!

You might be able to use expandAll() method after you render the treegrid

Thank you, but it seems that the "render" event is only thrown once when the grid is rendered the first time.

I added a render and afterrender listener to the gridView and gridView.ownerCt but it's not called after adding children to a node using the treestore.load() method.

How can I react to a nodes children beeing updated in the tree panel?

In that case you should use load event listener.
