    Hi, I have a mainform containing a radDock. Whenever I launch a new form they appear in the tabstrip. Is there any way to modify the tabstrips of some forms at runtime to show a number ?

     I would like it to look like notifications in chrome tabs.


    Thank you for the help !

    Hello, Sacha,    

    According to the provided information, it is not clear enough how exactly you show he form in RadDock. However, I would liek to note that RadDock has the capability of automatically finding and attaching Multiple Document Interface (MDI) child forms as tabbed documents. Additional information is available in the following help article:

    In order to customize the text and icon shown in the hosted form as a tabbed document, you need to handle the DockWindowAdded event. Please refer to the following help article which result is illustrated in the attached screenshot:

    public RadForm1()
        this.IsMdiContainer = true;
        this.radDock1.AutoDetectMdiChildren = true;
        this.radDock1.DockWindowAdded += radDock1_DockWindowAdded;
    private void radDock1_DockWindowAdded(object sender, Telerik.WinControls.UI.Docking.DockWindowEventArgs e)
        HostWindow hw = e.DockWindow as HostWindow;
        if (hw != null)
            hw.Image = Properties.Resources.about_paint;
            hw.Content.Text = "My text";
    private void radButton1_Click(object sender, EventArgs e)
        Form childForm = new Form();
        childForm.Text = "MDI Child " + DateTime.Now.ToShortTimeString();
        childForm.MdiParent = this;

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