Hi Support,
I have only one higher level node in tree. All child of that node are childless.
Checkbox is enabled .
Now when tree loads the first and only higher level node populates on the page. When I click on the node or + image all child comes from servlet. I want the state(checked or unchecked) of only node in the servlet, when childes are populated. So that I can check all child if parent is checked.
But what my problem is I am not able to pass any parameter to servlet regarding the state of parent.
How to pass that?
OR
Can I have control after tree loads? So that I can run any js code .
I just tried
categoryTree.loadXML(path,myFun());
categoryTree.setXMLAutoLoading(path,myFun());
But it dosent help
How to achieve by both ways?
Thanks
You can use the userdata functionality. It can be set for the 1-level item from the xml which contains child items.
For example, the xml with child items is as follows:
1
<item …/>
…
And when child item are loaded, the parent item (its id is “1”) will be checked:
tree.attachEvent(“onXLE”,function(id){
if(tree.getUserData(id,“checked”)) tree.setCheck(id,1);
})
