Hello, Steive,   

Following the provided information, I have prepared a sample code snippet for your reference:

        public RadForm1()
        {
            InitializeComponent();

            this.panel1.AllowDrop = true; 
           
            this.radTreeView1.MouseDown += radTreeView1_MouseDown;  

            this.panel1.DragEnter += Panel_DragEnter;
            this.panel1.DragDrop += Panel_DragDrop;
        }

        private void radTreeView1_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == System.Windows.Forms.MouseButtons.Left && this.radTreeView1.SelectedNode != null)
            {
                (this.radTreeView1).DoDragDrop(this.radTreeView1.SelectedNode, DragDropEffects.Copy);
            }
        }

        private void Panel_DragDrop(object sender, DragEventArgs e)
        {
            RadTreeNode node = e.Data.GetData(typeof(RadTreeNode)) as RadTreeNode;
            Console.WriteLine(node.Text);
        }

        private void Panel_DragEnter(object sender, DragEventArgs e)
        {
            e.Effect = DragDropEffects.Copy;
        }

The achieved result is illustrated in the attached gif file. It seems that everything works as expected on my end. Am I missing something?

I have attached my sample project. Please give it a try and see how it works on your end. 

The following MSDN article is quite useful about implementing drag and drop functionality: https://docs.microsoft.com/en-us/dotnet/desktop/winforms/advanced/walkthrough-performing-a-drag-and-drop-operation-in-windows-forms?view=netframeworkdesktop-4.8  

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
