Hello Yostec,

 There is no "out of the box" way tooltip on the RadDiagramShape. However, you can use MouseOver and MouseLeave events like so:

private ToolTip shapestoolTip;
        public MainPage()
        {
            InitializeComponent();
        }
        private void RadDiagramShape_MouseEnter(object sender, MouseEventArgs e)
        {
            shapestoolTip = new ToolTip();
            shapestoolTip.Content = "CustomTooltip";
            shapestoolTip.IsOpen = true;
        }
        private void RadDiagramShape_MouseLeave(object sender, MouseEventArgs e)
        {
            if (shapestoolTip != null && shapestoolTip.IsOpen == true)
            {
                shapestoolTip.IsOpen = false;
            }
        }

Furthermore. you can take a look at our MindMap and OrgChart Samples where custom MouseOver state is added to the MindMapShapes and OrgChartShapes (they inherit from RadDiagramShapeBase). On mouse over you can see some template parts are showing. Hope this might be helpful in some custom scenarios.
