I'm populating a treeview dynamically. On OnTreeNodePopulate I call a sub and populate the Parent nodes. I do not want to populate the child nodes at this time. Upto this point it works fine.
Now I would like the user to click the parent node and then populate the child node. I tried to use TreeNodeExpanded, but that is called for each parent node, so that didn't work.
I am trying to build a tree view and was able to create one.The tree is a multi-level tree(6 child levels). The problem I am facing is that for some node the node text is more than 260 characters and for those nodes the node is not expanding and showing the child nodes. I read in the web that the Max lenght for the node Text is 260 only. I am picking these node text values from database and they can be longer than the 260 mark.
