Xml for the tree:<br>
<xmp>
<tree..>
<item ...>
<userdata name=“myurl“>http://www.google.com</userdata>
<item ...>
<userdata name=“myurl“>http://groups.google.com</userdata>
</item>

<br>
there is an event handler for click processing:
<xmp>
tree.setOnClickHandler(doOnClick);
function doOnClick(nodeId){
var myUrl = tree.getUserData(nodeId,“myurl“);
window.open(myUrl);// or frames[“someframe“].location.href = myUrl
}
</xmp>
</div>
<!-- -->
<a name="spec_dnd_out"><h3 >Drag-n-drop outside tree</h3
></a><div style="display:show" class="block">
Any page control can be set as “landing zone”. Here is an example:
<xmp>
<div id="treeboxbox_tree" style="width:200;height:200"></div>
<input type="text" width="120px" id="sInput">
<script>
tree=new dhtmlXTreeObject("treeboxbox_tree","100%","100%",0);
tree.setImagePath("../imgs/");
//user defined drag and drop control with event handlers inside
function s_control(){
//action occures on drag
this._drag=function(sourceHtmlObject,dhtmlObject,targetHtmlObject){
targetHtmlObject.style.backgroundColor="";
targetHtmlObject.value=sourceHtmlObject.parentObject.label;
}
//action occures on drag moved in landing zone
this._dragIn=function(htmlObject,shtmlObject){
htmlObject.style.backgroundColor="#fffacd";
return htmlObject;
}
//action occures on drag moved out landing zone
this._dragOut=function(htmlObject){
htmlObject.style.backgroundColor="";
return this;
}
}
//set input control as “landing zone”
tree.dragger.addDragLanding(document.getElementById('sInput'), new s_control);
</script>
