Hi all, I have some problems with displaying the nodes that are added to the tree for the first time. When I double click on any node, I query the database and depending on the no. or rows got I just add the nodes to the tree. I'm using treemodel.insertNodeInto method for this. But the first time the app is loaded and I double-click on a node, It gets the proper data from the database, adds the nodes but they won't show up. I'm currently doing an expand of that node explicitly. This expansion is not desirable b'cos when I double-click again on that node I want it to collapse, which wont happen in my case b'cos I have given an Explicity expand row. But strangely enough, when my tree is expanded and when I add a new node to the existing node or update it (for which I'm using the same IsnertNodeInto method), things work fine. Its just the first time when I double-click on the root node , the children won't show up. Any help is appreciated -----== Posted via Deja News, The Leader in Internet Discussion ==----- http://www.dejanews.com/rg_mkgrp.xp Create Your Own Free Member Forum
