垣間見ることができるMVCアプリケーションがインストールされています。また、動的検証にMVCControlToolkitを使用しています。
私が抱えている問題は、DateTimeForを使用して検証付きの日時カレンダーを表示するビューがある場合ですが、非常に限られた状況でのみ（datetimefor要素しかない場合はこれは発生しません）、本文がレンダリングされますページを2回。
レンダリングが何かによって再開されているように見えますが、私はそれを解決することができませんでした。
どんな助けでもいただければ幸いです
私のビューコードは
@using LeaveTracker.Models
@using LeaveTracker.Models.Leave
@using MVCControlsToolkit.Controls
@using MVCControlsToolkit.Controls.Validation
@model LeaveTracker.Models.Leave.LeaveAllocation
@{
ViewBag.Title = "Edit";
Layout = "~/Views/Shared/_LayoutMaintenance.cshtml";
}
@Html.AntiForgeryToken()
<div class="page-header">
<h1>
Edit Leave Allocation
@if (Model.ID > 0) { <small> @Model.TypeOfLeave.Name till @Model.AppliesUntil.ToString("dd/MM/yyyy")</small> }
