Thank you, logic below worked:



var ids=tree.getAllSubItems(0).split(",")

var check={}

for (var i=0; i<ids.length; i++){

var label=tree.getItemText(ids[i]);

if (!check[label]) check[label]=true;

else tree.deleteItem(ids[i]); //delete duplicate



However, I would like to keep duplicate node highlighted, and return it’s default value ( ex: New Item[1] ). I am trying to use stopEdit(), it doesn’t work:



var hasChildrenCheck = tree.hasChildren(treeitemId);

                tree.attachEvent(“onEdit”,function(){

                var booleanVar = true;

                if(hasChildrenCheck > 0 ){

                var ids = tree.getAllSubItems(treeitemId).split(",");

                var check={};

                for (var i=0; i<ids.length; i++){

                

                var label=tree.getItemText(ids[i]);

                 if (!check[label]) {

             check[label]=true;

                    booleanVar=true;

                    }

                else {

             //    tree.focusItem(selectedItem);            

                tree.stopEdit();

            //    tree.deleteItem(ids[i]); //delete duplicate

                booleanVar=false;

                }

                }

                } return booleanVar;

});



Please help,

Thank you

IF you want to prevent duplicates as result of in-tree edit, it can be done as


tree.attachEvent(“onEdit”,function(stage,id,tree,value){
if (stage==2){ //before editor closed
var ids=tree.getAllSubItems(0).split(",");
for (var i=0; i<ids.length; i++)
if (tree.getItemText(ids[i])==value) return false; //revert to old value if there is a duplicate
}
return true;
})
