so have treeview , checking duplicates. if add node tree , try add same node, code won't let happen. want. need check child nodes, if root nodes same if first child of root node different 1 being added, want add child nodes under root node that's there. have tried: if(node.text == root.text && node.firstnode.text == root.firstnode.text) nodes.remove(node); but gives me null exception on root.firstnode.text , i'm not sure why getting null when node.firstnode.text shows child node. any suggestions appreciated. it means whatever node you've assigned root has no children (hence root.firstnode null). node.firstnode can still show it's first child node if whichever node assigned 1 different 1 assigned root . the important thing here because have same text, doesn't mean same node. judging code provided, referring different object (with different collections of child nodes, or lack of) i'm imagining following (not actual c...
