You've configured local filtering - see the docs for this setting - it means criteria are not sent to the server. Remove this setting.

Setting initialData is not necessary.

"rootValue" is set in .ds.xml as simply rootValue="someValue". It's just like all the other settings in the docs.

initialData

Hello,

Well I am on the route down initialData for several reasons. And tend to think it is the right call. I want to have more control about when requests are occurring.

For example my outline of design is that I load a "subset tree" of our huge tree of data. And then set initial data to this subset tree. Then when a user desires they may "load on demand" any node, which will pull back all children - even ones outside my subset tree.

So the attached code is my current setof initial data on a tree. And it does now load the data and show it in the tree.

However, it does not see it as a parent/child tree. Even though I have set the treenodes and id/parent settings.

What else do I set for the treeGrid so it knows to render a tree here?

Is there some other flaw in what I have done that I don't see?

isfolder

Hello,

I update my code so that the "internal nodes" are setting isfolder true. Which now has my nodes showing folders and my leaves not. But still they are not showing as a tree, just a list. I can clearly see the id and parentid I am setting for each node and they are correct. So it should show a tree.

What other settings are there to try?

To get the root node I am doing two things
1. likely not needed
ResultTree rTree = new ResultTree();
rTree.setModelType(TreeModelType.PARENT);
rTree.setRootValue("0");
treeGrid.setDataProperties(rTree);

2. on the data source
The java code
final DataSource ds = DataSource.get(DataSourceInfo.PARENTS_SEARCH_ENITITES_DATASOURCE_MYSQL);
treeGrid.setDataSource(ds);
treeGrid.setFetchOperation(eCurrentSearchOnType.getOpIDSearchEntities());

and in my .ds.xml file
<fields>
<field primaryKey="true" name="entkey" type="integer" title="id"></field>
<field name="parentkey" type="integer" title="parent" foreignKey="entkey" rootValue="0"></field>

where I have a root node define as

private TreeNode getRootTreeNode() {
TreeNode n = new TreeNode();
n.setIsFolder(true);
n.setID("0");
n.setParentID("0");
n.setTitle("root");
return n;
}

almost there

Hello,

How can I have the tree I created start in the "open" position and not collapsed. I tried treeGrid.getData().openAll()
but that crashed me.

Attached is my working code so far.

Next adding children :-)

Thanks,
Evan

openAll and openFolder not always working

Hello,

Sometimes it opens the tree on render sometimes not.
First I tried the example of having the tree open by using the
That is the example from the showcase
Tree/Appearance/Node Titles where
There is an addDAtaArrivedHandler.
the .getData.openAll()
I did try it (see the commented out code in attached file). It did not work at all ...

This did not work, not sure off hand it fired, perhaps because I am getting the data manually (see attached code) and then using the initialData?

So with that not working I tried what I am currently using which is the "doOnRender" function and having it open the first 15 folders which is what I want. I don't want to actually openAll, as it is to slow for us. While just iterating and opening the first 15 I think is slick enough.

So where did I go wrong? I will continue to tweak and play with it, perhaps I will find it.

Currently it opens sometimes, and others not. So clearly a timing issue (at least).

Thanks,
Evan
