Anyone know why my MobileModalView form appears for a split second on my page load? It's a stripped down version with no style, but it appears and then goes away. I modified the ModalMobileView demo to test the basics of the MobileModalView feature and included a form and some a few other small changes. Could the addition of a form cause this some how?

Here's my cshtml:

 @{

    Layout = "~/Views/Shared/_LayoutMobile.cshtml";

}


@model MyProjectWeb.Models.LoginModel




@(Html.Kendo().MobileView()
        .Name("modalview-camera")
        .Title("MyProject")
        .Content(
        @<text>

            <img src="@Url.Content("~/Content/photos/NewLogoTrimmed.JPG")" class="camera-image" style="width: 100%; height: 100%;" />
<br/>
<br />
<br />
<br />
<br />
<br />
            @(Html.Kendo().MobileButton()
                        .Text("Login")
                        .Name("modalview-open-button")
                        .Rel(MobileButtonRel.ModalView)
                        .Url("#modalview-login")
            )
        </text>)
)

@(Html.Kendo().MobileModalView()
       .Name("modalview-login")
       .HtmlAttributes(new { style = "width: 95%; height: 18em;" })
       .Header(obj =>
           Html.Kendo().MobileNavBar()
                .Content(navbar =>
                    @<text>
                        <span>Login</span>
                        @(Html.Kendo().MobileButton()
                            .Text("Cancel")
                            .Align(MobileButtonAlign.Right)
                            .Events(events => events.Click("closeModalViewLogin"))
                        )
                    </text>)
        )
        .Content(
        @<text>
            @ModalViewContentTemplate()
        </text>)
)

@helper ModalViewContentTemplate()
{
    using (Html.BeginForm("LogOn", "Account", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" })) {

                            @Html.ValidationMessageFor(m => m.UserName, "", new { @class = "text-danger" })
                        </text>);
                    items.Add().Content(

Here's a demo: http://runner.telerik.io/fullscreen/ICoqi

If you refresh the page a few times and watch closely you will see the generic html form appear at the bottom for a split second.

Hi,

the behavior you refer to is commonly known as FOUC. There are many means to avoid it, but it is not specific to the kendo mobile application, so you may pick the one you find most suitable.
