I am binding my hierarchical data to the xamDataTree and trying to implement the load on demand functionatlity, where child items are loaded once the parent is expanded. But if I only bind the parent items to the tree i am not able to see any expand icon. My scenerio is that i would only know the child once parents are expanded. So I wanted to know is there any ways in which I can show the expand icon no matter if there are any child items or not, and then when the parent is expanded depending on the child items count the node is expanded.
