    <p>I have a base Controller like follow</p> <pre><code> public abstract class BaseController { protected ActionResult LogOn(LogOnViewModel viewModel) { SaveTestCookie(); var returnUrl = ""; if (HttpContext != null &amp;&amp; HttpContext.Request != null &amp;&amp; HttpContext.Request.UrlReferrer != null) { returnUrl = HttpContext.Request.UrlReferrer.LocalPath; } TempData["LogOnViewModel"] = viewModel; return RedirectToAction("ProceedLogOn", new { returnUrl }); } public ActionResult ProceedLogOn(string returnUrl) { if (CookiesEnabled() == false) { return RedirectToAction("logon", "Account", new { area = "", returnUrl, actionType, cookiesEnabled = false }); } var viewModel = TempData["LogOnViewModel"] as LogOnViewModel; if (viewModel == null) { throw new NullReferenceException("LogOnViewModel is not found in tempdata"); } //Do something //the problem is I missed the values which are set in the ViewBag } } </code></pre> <p>and another Controller </p> <pre><code>public class MyController : BaseController { [HttpPost] public ActionResult LogOn(LogOnViewModel viewModel) { // base.LogOn is used in differnet controller so I saved some details in view bag ViewBag.Action = "LogonFromToolbar"; ViewBag.ExtraData = "extra data related only for this action"; return base.LogOn(viewModel); } } </code></pre> <p>the problem is I missed the view bag values in ProceedLogOn action method. I have the values in Logon method in BaseController.</p> <p>How can I copy the values of ViewBag from one Action to another Action?</p> <p>So I can not simply say <code>this.ViewBag=ViewBag;</code></p> <p>because ViewBag doesn't have setter. I was thinking of Iterating through viewbag. I tried <code>ViewBag.GetType().GetFields()</code> and <code>ViewBag.GetType().GetProperties()</code> but they return nothing.</p>

    1. COI know It's better to use TempData , but I don't want to change an existing functionality!!

    2. COI think you should receive the `ViewBag` values and set it again in the other action, in your example in the `LogOn` view you may save the data in hidden field or model property and send it again.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
