问如何在DevExpress MVC标签页中设置tabpage内部控件的焦点？

EN

@Html.DevExpress().PageControl(
settings =>
{
    settings.Name = "myTabs";
    settings.CallbackRouteValues = new { Controller = "Tabs", Action = "CallbackTabs" };

    settings.TabPages.Add("Tab1").SetContent(() =>
    {
        ViewContext.Writer.Write("<div class='tab1Content'>");
            Html.RenderAction("GetTab1", "Tabs");
        ViewContext.Writer.Write("</div>");
    });
    settings.TabPages.Add("Tab2").SetContent(() =>
    {
        ViewContext.Writer.Write("<div class='tab1Content'>");
            Html.RenderAction("GetTab2", "Tabs");
        ViewContext.Writer.Write("</div>");
    });
}

    public ActionResult GetTab1()
    {
        return PartialView("_Tab1", result);
    }

    public ActionResult GetTab2()
    {
        return PartialView("_Tab2", result);
    }
