[CLOSED] StartCollapsed in GridPanel and remote paging

[SuperBolt]

Hello!

If I use StartCollapsed in GridPanel + Grouping and remote Paging, If change the page, parameter StartCollapsed is reset - false. It is not right.

Source code

Index.cshtml

@using Ext.Net.MVC

@model ICollection<ExtNetTest.Models.StageItemModel>

@{
    ViewBag.Title = "";
    Layout = "~/Views/Shared/_BaseLayout.cshtml";
    var X = Html.X();
}

@section bodySection
{
    @(X.Viewport()
          .MinWidth(1245)
          .MinHeight(600)
          .Layout(LayoutType.Border)
          .AutoScroll(true)
          .Items(
              X.GridPanel()
                  .ID("gpnlCalPlan")
                  .Title("CalPlan")
                  .Region(Region.Center)
                  .Flex(1)
                  .Frame(true)
                  .Store(
                      X.StoreForModel()
                          .Proxy(X.AjaxProxy()
                              .Url(Url.Action("LoadCalendarPlan"))
                              .Reader(X.JsonReader().RootProperty("data"))
                              .ActionMethods(methods => methods.Read = HttpMethod.POST)
                          )

                      X.Column().DataIndex(Model, m => m.Name).Text("Stage Name").MinWidth(150).Flex(1)
                  )
                  .BottomBar(
                      X.PagingToolbar()
                  )
                  .View(
                      Html.X().GridView()
                  )
                  .Features(
