A simple example which illustrates how to save RadDock state on postback is available here:
http://demos.telerik.com/ASPNET/Prometheus/Dock/Examples/LoadSaveLayout/DefaultCS.aspx

To achieve your goal you should wrap the RadDockLayout with UpdatePanel and set RadDock.AutoPostback to true(position will be saved on each raddock move),e.g.
ASPX:

    
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!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>Untitled Page</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager> 
        
                <div> 
        
                <asp:UpdatePanel ID="UpdatePanel1" runat="server">  
        
                    <ContentTemplate> 
        
                <telerik:RadDockLayout ID="RadDockLayout1" runat="server" 
        
                OnLoadDockLayout="RadDockLayout1_LoadDockLayout" 
        
                OnSaveDockLayout="RadDockLayout1_SaveDockLayout" 
        
                > 
        
                    <telerik:RadDockZone ID="RadDockZone1" runat="server">  
        
                        <telerik:RadDock ID="RadDock1" runat="server" Title="RadDock1" AutoPostBack="true"/>  
        
                        <telerik:RadDock ID="RadDock2" runat="server" Title="RadDock2" AutoPostBack="true"/>  
        
                    </telerik:RadDockZone> 
        
                    <telerik:RadDockZone ID="RadDockZone2" runat="server">  
        
                        <telerik:RadDock ID="RadDock3" runat="server" Title="RadDock3" AutoPostBack="true"/>  
        
                    </telerik:RadDockZone> 
        
                </telerik:RadDockLayout> 
        
                </ContentTemplate> 
        
                </asp:UpdatePanel> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>
