    <p>You can decorate a controller with the OutputCache attribute which allows arguments to be passed as parameters. For example;</p> <pre><code>[OutputCache(Duration = 3600, VaryByParam = "None")] </code></pre> <p>There is no reason why you couldn't extend the attribute to take a further argument "RoleName" and perform a "Roles.IsUserInRole(RoleName)" and load different settings based upon each role.</p> <p>EDIT</p> <p>After comments from the author, I have reviewed my solution.</p> <p>Firstly, you can define you cache profiles within the Web.config;</p> <pre><code>&lt;caching&gt; &lt;outputCacheSettings&gt; &lt;outputCacheProfiles&gt; &lt;clear /&gt; &lt;add name="Default" duration="60" /&gt; &lt;add name="Admin" duration="10" /&gt; &lt;/outputCacheProfiles&gt; &lt;/outputCacheSettings&gt; &lt;/caching&gt; </code></pre> <p>I have extended the OutputCacheAttribute to account for authorisation of a user, and if the user authenticates, it loads that CacheProfile;</p> <pre><code>public class AuthorisedOutputCache : OutputCacheAttribute { public string RoleName { get; set; } public override void OnActionExecuting(ActionExecutingContext filterContext) { // Default Profile. CacheProfile = "Default"; if (HttpContext.Current.Request.IsAuthenticated) { if (Roles.IsUserInRole(RoleName)) { CacheProfile = RoleName; } } base.OnActionExecuting(filterContext); } } </code></pre> <p>Here is the Index.cshtml file for completeness;</p> <pre><code>@model DateTime @{ ViewBag.Title = "Index"; } &lt;h2&gt;Index&lt;/h2&gt; &lt;p&gt; The time is @Model.TimeOfDay.ToString() &lt;/p&gt; </code></pre> <p>Note: You will have to make sure to define a cacheprofile for each of your roles, aswell as a default for when no role is found.</p> <p>EDIT</p> <p>The author wished to know how to set the cache profile within the controller, I have posted a viable solution, but I don't like it because of the use of HttpContext.Items - so if anyone can suggest alternatives?</p> <p>Firstly, you must change the OnActionExecuting to OnActionExecuted;</p> <pre><code>public class AuthorisedOutputCache : OutputCacheAttribute { public string RoleName { get; set; } public override void OnActionExecuted(ActionExecutedContext filterContext) { // Do you wish to force the profile? if (HttpContext.Current.Items["Cache.Force"] != null) { // Force the profile and remove the flag. CacheProfile = HttpContext.Current.Items["Cache.Force"].ToString(); HttpContext.Current.Items.Remove("Cache.Force"); } else { // If the profile has not been set - use the role based authorisation - // otherwise, carry on as normal. if (string.IsNullOrEmpty(CacheProfile)) { CacheProfile = "Default"; if (HttpContext.Current.Request.IsAuthenticated) { if (Roles.IsUserInRole(RoleName)) { CacheProfile = "Admin"; } } } } base.OnActionExecuted(filterContext); } } </code></pre> <p>The following line allows you to set the profile within the controller;</p> <pre><code>public ActionResult Index() { // Forces the cache profile to one of the name of "Mandatory". HttpContext.Items["Cache.Force"] = "Mandatory"; return View(IndexViewName, DateTime.Now); } </code></pre> <p>Let me know if I can be of further assistance,</p> <p>Matt </p>

    1. COThanks. Looks like any place that accept a temp value can be used for this method. How about viewbag? I will try this method now, have to say, change the method from OnActionExecuting to OnActionExecuted is a smart move.

    2. COHi Matt, after test. Change CacheProfile @ OnActionExecuting is working, but @ OnActionExecuted is not. The value for CacheProfile is changed but the cache result is not. Maybe the cache has already been deployed after OnActionExecuting but before OnActionExecuted.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
