In the project, when a node is added, a string is appended with the value. Once the node is removed, the text values must be read and removed from the string. I was able to accomplish this using the following:

function removeNode(whichTree, whichHF) {
var node = $(whichTree).igTree("selectedNode");
var nodeChildren = $(whichTree).igTree("childrenByPath", node.path);
//alert(nodeChildren.length);
var replaceStr = node.data.Text;
var idx = 0;
if (nodeChildren.length > 0) {
while (idx < nodeChildren.length) {
// Get root nodes.
var nestedNode = nodeChildren[idx].data.Text;
replaceStr += nestedNode;
//alert(replaceStr);
idx++;
}
}
//alert(replaceStr);
replaceText(whichHF, replaceStr, "");
if (node.path != null) {
// Remove selected node using path
$(whichTree).igTree("removeAt", node.path);
$(whichTree).igTree("clearSelection");
}
}

Hello Big_Lebowski,

Thank you for contacting Infragistics community.

As far as I understood your explanation, you want to get the text of any selected node's child node. Is that right?

If this is the case, then I would suggest you to do that on selectionChanged event, for instance:

selectionChanged: function (evt, ui) {

           // this will return "United States" as result based on the following sample code - http://igniteui.com/tree/overview
          var childNodeText = ui.selectedNodes[0].element[0].children[2].children[0].children[0].innerHTML;         
      }

I'm attaching also a sample for your reference. Please let me know if you have any further questions.

Sincerely,

Tsanna
