Adding an image to a RadTreeNode is a simple process that can enhance

Hello, I'm currently working on creating a dynamic treeview that is based on the onClick event of a menu item.

function onClick(sender, eventArgs) {
 var treeView = $find("<%= RadTreeView1.ClientID %>");
 var selectedNode = treeView.get_selectedNode();        
 var node = new Telerik.Web.UI.RadTreeNode(); 
 var parent = treeView.get_selectedNode();
 node.Image= "~/Images/Folder-Add-icon.png";
 parent.get_nodes().add(node);
 treeView.commitChanges();
}

However, I am encountering an issue where the image does not appear next to the added node. What could be causing this problem?

Answer №1

It appears that the trackChanges() method of the treeview was unintentionally skipped before creating the new node.

    function onClicked(sender, eventArgs) {
     var treeView = $find("<%= RadTreeView1.ClientID %>");
     treeView.trackChanges();       
     var node = new Telerik.Web.UI.RadTreeNode(); 
     var parent = treeView.get_selectedNode();
     node.Image= "~/Images/Folder-Add-icon.png";
     parent.get_nodes().add(node);
     treeView.commitChanges();
}
