If you want to set a new text to the title you could handle RadDock's OnClientInitialize client side event and set RadDock's title via JavaScript, e.g.
$find("RadDock1").set_title("newText");
Another approach is to add UpdatePanels in ContentTemplate and TitleBarTemplate and add triggers to the UpdatePanels , e.g.
ASPX:

    
            <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml">  
        
            <head id="Head1" runat="server">  
        
                <title></title>  
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server" > 
        
                </asp:ScriptManager> 
        
                <div> 
        
                <telerik:RadDockLayout ID="RadDockLayout1" runat="server">  
        
                             <telerik:RadDockZone ID="RadDockZone1" runat="server">  
        
                                <telerik:RadDock ID="RadDock1" runat="server">  
        
                                    <TitlebarTemplate> 
        
                                        <asp:UpdatePanel ID="UpdatePanelTitle" runat="server" > 
        
                                            <ContentTemplate> 
        
                                                <asp:Label ID="lblTitle" runat="server"></asp:Label> 
        
                                            </ContentTemplate> 
        
                                        </asp:UpdatePanel> 
        
                                    </TitlebarTemplate> 
        
                                    <ContentTemplate> 
        
                                        <asp:UpdatePanel ID="UpdatePanelContent" runat="server">  
        
                                            <ContentTemplate> 
        
                                                <asp:Label ID="lblContent" runat="server"></asp:Label>     
        
                                            </ContentTemplate> 
        
                                        </asp:UpdatePanel> 
        
                                    </ContentTemplate> 
        
                                </telerik:RadDock> 
        
                             </telerik:RadDockZone>    
        
                 </telerik:RadDockLayout> 
        
                 <asp:Button ID="Button1" runat="server" Text="Postback"/>   
        
                 <asp:Label ID="Label1" runat="server" Text="aaa"></asp:Label>    
        
                  </div> 
        
                </form> 
        
            </body> 
        
            </html>

Codebehind:

    
            protected override void OnInit(EventArgs e)  
        
                {  
        
                    base.OnInit(e);  
        
                    AsyncPostBackTrigger btnClickTrigger = new AsyncPostBackTrigger();  
        
                    btnClickTrigger.ControlID = "Button1";  
        
                    btnClickTrigger.EventName = "Click";  
        
                    UpdatePanelContent.Triggers.Add(btnClickTrigger);  
        
                    UpdatePanelTitle.Triggers.Add(btnClickTrigger);  
        
                }  
        
                protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    Label1.Text = System.DateTime.Now.ToString();  
        
                    ((Label)RadDock1.TitlebarContainer.FindControl("lblTitle")).Text = System.DateTime.Now.ToString();  
        
                    ((Label)RadDock1.ContentContainer.FindControl("lblContent")).Text = System.DateTime.Now.ToString();  
        
                }

You can dynamically add Controls to the TitleBarContainer Controls collection in the following way:

For an example if you have a RadDock in the .aspx

    
                    <telerik:RadDockLayout ID="RadDockLayout1" runat="server"> 
        
                        <telerik:RadDockZone ID="RadDockZone1" runat="server" Height="300px" Width="300px"> 
        
                            <telerik:RadDock ID="RadDock1" runat="server" Width="300px" Title="RadDock-Title"> 
        
                                <ContentTemplate> 
        
                                    <asp:Label ID="Label1" runat="server" Text="TextNotChanged"></asp:Label> 
        
                                </ContentTemplate> 
        
                            </telerik:RadDock> 
        
                        </telerik:RadDockZone> 
        
                    </telerik:RadDockLayout>

When the page initializes we can add a LinkButton control to its TitleBarContainer, and attach an event handler method to the LinkButton Click event:

    
            protected void Page_Init(object sender, EventArgs e) 
        
            { 
        
                LinkButton LinkButton1 = new LinkButton(); 
        
                LinkButton1.Text = "LinkButton Text"; 
        
                // attach an event handler to the Click event 
        
                LinkButton1.Click += new EventHandler(LinkButton_Click); 
        
                // add the LinkButton to the RadDock's TitleBar template 
        
                RadDock1.TitlebarContainer.Controls.Add(LinkButton1); 
        
            } 
        
            protected void LinkButton_Click(object sender, EventArgs e) 
        
            { 
        
                Label1.Text = DateTime.Now.ToString(); 
        
            }
