Re: [flexcoders] Opening root node to show it's children just after loading data

Thu, 01 Jun 2006 14:45:34 -0700

Ok, that worked thanks Tracy!

at the expense of looking like a total idiot, I'll show you the janky way I did it though:

I created an XMLList from an xml string called XMLDoc.  I set the dataProvider of the tree with the XMLList then did this:
tree.expandItem(XMLDoc.children().parent(), true);

This seems retarded, and I know there's a very simple "hey, just access XMLDoc.root" type of thing, so that's why I'm posting this ;)

Thanks agian for the help,

If you want to open the root tree node, use the root node of the dataProvider xml. Are you binding or using a result handler?

Yeah, I saw that, but how do I get "item"?  That's what's throwing the error

tree.selectedItem = 0  - I get an error

Thoughts?

Use tree1.expandItem([item:Object],openorclose:Boolean).

 

item:Object would be the root node of the xml dataProvider.

This no longer works in beta3, any updates on how it's actually done?

 

Expanding a tree node

By default, the 


 
 
Tree
 control displays the root nodes of the 


 
tree
 when it first opens. If you want to expand a node of the 




 
tree
 when the 


 
tree
 opens, you can use the 

setIsOpen() method of the 


 
Tree
 control. The following example calls this method as part of the handler for the 

creationComplete
 event to expand the first root node of the 


 
tree
: <mx:Script>




    <![CDATA[




        function init


 
Tree
(){




            


 
tree
1.setIsOpen(


 
tree
1.getNodeDisplayedAt(0), true);




        }




        ]]>




    </mx:Script>









<mx:




 
Tree
 id="


 
tree
1" ... creationComplete="init


 
Tree
();" >




    ...




</mx:




 
Tree
