e.Positions is Empty

[Alec]

I have a radDockLayout which somehow has the e.Positions being empty.

 <telerik:RadDockLayout runat="server" ID="RadDockLayout1" OnLoadDockLayout="RadDockLayout1_LoadDockLayout" onsavedocklayout="RadDockLayout1_SaveDockLayout" storelayoutinviewstate="false">
                                       <div class="signature">

                                            <asp:Panel ID="pnlPreview" runat="server" CssClass="zones"></asp:Panel>
                                             <br /><br /><asp:Button ID="btnSave" runat="server" Text="Save Layout"  />&nbsp; &nbsp;

                                       </div>

                                       <div class="preview">
                                            <asp:Repeater ID="rptContentType" runat="server" OnItemDataBound="rptContentType_OnItemDataBound">
                                                <HeaderTemplate><ul id="contentlibrary"></HeaderTemplate>

                                                    <h2>
                                                        <span class="title"><%#DataBinder.Eval(Container.DataItem,"Title") %></span>

                                                        <telerik:RadDockZone id="radDockZone" runat="server" Height="150"></telerik:RadDockZone>
                                                        <asp:Repeater ID="rptContentLibrary" runat="server" OnItemDataBound="rptContentLibrary_OnItemDataBound"></asp:Repeater>
                                                    </li>
                                                </ItemTemplate>
                                                <FooterTemplate></ul></FooterTemplate>

                                            </asp:Repeater>

                                       </div>
                                </telerik:RadDockLayout>

  protected void RadDockLayout1_LoadDockLayout(object sender, Telerik.Web.UI.DockLayoutEventArgs e)
        {
            HttpCookie positionsCookie = Request.Cookies[Request["id"] + "CompanyEmailLayout"];
            if (!Object.Equals(positionsCookie, null))
            {
                string serializedPositionsAndIndices = positionsCookie.Value;
                if (!string.IsNullOrEmpty(serializedPositionsAndIndices))
                {
                    JavaScriptSerializer serializer = new JavaScriptSerializer();
                    string[] positionsAndIndices = serializer.Deserialize<string[]>(serializedPositionsAndIndices);

                    e.Positions = serializer.Deserialize<Dictionary<string, string>>(positionsAndIndices[0]);
                    e.Indices = serializer.Deserialize<Dictionary<string, int>>(positionsAndIndices[1]);
                }
            }
        }

        protected void RadDockLayout1_SaveDockLayout(object sender, Telerik.Web.UI.DockLayoutEventArgs e)
        {
            JavaScriptSerializer serializer = new JavaScriptSerializer();
            string serializedPositions = serializer.Serialize(e.Positions);
            string serializedIndices = serializer.Serialize(e.Indices);

            HttpCookie positionsCookie = new HttpCookie(Request["id"] + "CompanyEmailLayout",
                serializer.Serialize(new string[] { serializedPositions, serializedIndices }));

            //Ensure that the cookie will not expire soon
            positionsCookie.Expires = DateTime.Now.AddYears(1);
            Response.Cookies.Add(positionsCookie);

            if (IsPostBack)
            {
                //my codes

            }
        }

The problem is ... somehow, when i click on the save button, and breakpointing into //my codes, the e.Positions and Indices have empty content. That's really weird. Am I missing something?

Solved. I had !IsPostBack in page_init...
