The valuepath string sytax for FindValueByNode method : "<resourcename>" or "<resourcename>/<layerid>"Sample Code to find all possible valuepaths for a given TOC Control:C#:===foreach (TreeViewPlusNode t1 in Toc1.Nodes){ // get value path of earch resource if needed string rvp = t1.ValuePath; //get the name of the resource string rname = t1.Text foreach (TreeViewPlusNode t2 in t1.Nodes) { //get the valuepath of each layer inside the resource string vpath = t2.ValuePath; //get the name of layer string layername = t2.Text; }}
