Loading a PartialPage inside a TabStrip after Postback from ComboBox doesn't render parent

[Lukasz]

Hi, I'm using a Grid inside a TabStrip and a Combobox for filtering. First time it loads correctly, but after I do a postback from the ComboBox it loads only the PartialPage instead of reloading the Partial inside the TabStrip.

div class="btn-group">
    @using (Ajax.BeginForm("Rules", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "Rules", InsertionMode = InsertionMode.Replace }))
    {
        @Html.AntiForgeryToken()
        <label>Account No</label>
        @(Html.Kendo().DropDownList()
                                              .Name("selectedAccountNo")
                                              .DataTextField("Value")
                                              .DataValueField("Text")
                                              .BindTo(Model.selectedAccNo)
                                              .HtmlAttributes(new { style = "width: 100%" })
        )
        <br />


        <label> Application </label>
        @(Html.Kendo().DropDownList()
                                              .Name("selectedAppNo")
                                              .DataTextField("Value")
                                              .DataValueField("Text")
                                              .BindTo(Model.selectedAppNo)
                                              .HtmlAttributes(new { style = "width: 100%", @onchange = "this.form.submit();" })
        )
    }

And In the _Layout page:

<div class="form-header">
       <div class="md-sidenav-left" id="v-pills-tab" role="tablist" aria-orientation="vertical">
           @(Html.Kendo().Button()
                 .Name("Home")
                 .HtmlAttributes(new {type = "button", @class = "k-primary", href = "../Home/#"})
                 .Content("Home")
                 .Events(ev => ev.Click("onHomeClick")))
           @(Html.Kendo().Button()

Solved using grid filtering.
