Is there any way to add a checkbox node and have child nodes under that node without checkboxes? I've tried this code and it didn't work
UltraTreeNode utnRole = new UltraTreeNode();
Well, one of the lines of code you have here won't compile and doesn't seem to do anything, anwyay. So I had to remove it:
tn.Nodes.Add(new TreeNode(strUserInGroup));
Once I do that, though, I get a parent node in the tree with a checkbox and a child node with no checkbox. Is that not what you are getting?
What version of the tree do you have?
