    <p>OutputCaching on the main controller actions seems to work fine but for PartialViews they don't seem to work as expected. </p> <p>I added the attribute in one of the partialviews, debugged it. I continuously hit the breakpoint inside the method (which i think means output caching isn't working). I tried providing parameters, cacheprofiles, enablingoutputcaching and fragments but same effect. Is there something else that I am missing?</p> <pre><code>[ValidateInput(false)] [OutputCache(Duration = 60000, VaryByParam = "componentId;")] public PartialViewResult NewCategoryComboPartial(string componentId) { //ComponentId ViewData[ControllerEnums.GlobalViewDataProperty.ComponentId.ToString()] = componentId; //ViewModel ViewData[ControllerEnums.GlobalViewDataProperty.ProfileComponentCategories.ToString()] = GetComponentCategoriesList(); return PartialView("~/Views/Compliance/Profile/Partials/NewCategoryCombo.ascx"); } </code></pre> <p>Is it because of an existing action filter? ValidateInputAttribute? My PartialView()? </p> <p>Thanks in advance.</p> <p><strong>UPDATE:</strong></p> <p>Below is the code snippet from the main view on how the partialview is declared.</p> <pre><code> &lt;div id="compliance-navigation-control"&gt; &lt;% Html.RenderPartial("~/Views/Shared/Compliance/ComplianceNavigationControl.ascx", Model.PandCRecord); %&gt; &lt;/div&gt; </code></pre> <p>Below is the content of the partialview</p> <pre><code>&lt;%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl&lt;dynamic&gt;" %&gt; &lt;%@ Import Namespace="atp.webnav.Web.Controllers" %&gt; &lt;%@ Import Namespace="atp.webnav.Web.Utilities" %&gt; &lt;% Html.DevExpress().ComboBox(x =&gt; { x.Name = "categoryComboBox_" + ViewData[ControllerEnums.GlobalViewDataProperty.ComponentId.ToString()].ToString(); x.Theme = "Glass"; x.Width = Unit.Percentage(100); x.Properties.ValueType = typeof(string); x.Properties.TextField = "Name"; x.Properties.ValueField = "Id"; x.SelectedIndex = 0; x.Properties.DropDownStyle = DropDownStyle.DropDown; x.Properties.MaxLength = 30; x.Properties.IncrementalFilteringMode = IncrementalFilteringMode.StartsWith; x.Properties.AllowUserInput = true; x.CallbackRouteValues = new {Controller = "Profile", Action = "NewCategoryComboPartial"}; x.Properties.EnableCallbackMode = true; x.Properties.CallbackPageSize = 1000; x.Properties.ClientSideEvents.BeginCallback = "webnav.compliance.profile.categoryComboBox_OnBeginCallback"; x.Properties.ClientSideEvents.SelectedIndexChanged = "webnav.compliance.profile.categoryComboBox_OnSelectedIndexChanged"; x.Properties.ClientSideEvents.EndCallback = "webnav.compliance.profile.categoryComboBox_OnSelectedIndexChanged"; x.Properties.ClientSideEvents.CallbackError = DevExpressGridViewHelper.HandleCallbackErrors; x.Properties.EnableSynchronizationOnPerformCallback = true; }) .BindList(ViewData[ControllerEnums.GlobalViewDataProperty.ProfileComponentCategories.ToString()]) .Render(); %&gt; </code></pre> <p>Essentially this combobox is a devexpress combobox that has autocomplete features. It uses callbacks to the controller actions to get the data based on the value selected. I am trying to see if I can cache the results of the callback. Thanks.</p>

    1. COI'm not sure if this is the cause of your issue, but you may need to get rid of the semicolon after componentId in VaryByParam

    2. COAgreed - i think that's it. Output caching on PartialViews **does** work (i used it all over the place). And yes @llapinski's points are valid too.

    3. CObwisitero says he put break points, which were hit, so I guess my response might not be valid. Just a guess - maybe you call action method directly from page, for instance you use T4MVC, and Action method with parameter ActionResult and did not regenerate templates?

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).
