Sense/Net ECMS is all about content. Creating, modifying and displaying content is essential part of this system and displaying multiple content is the most commonly used feature of Sense/Net. Content collection Portlet is one of the three main portlets aiding this task (the other ones are the Content List Portlet that can be used to display items or files that reside in a content list and the Content query presenter Portlet that is built on a simple Content Query).


Content collection Portlet is able to display multiple content on portal pages. The most common examples are news or article lists, latest memos, simple menus or top rated products. The displayed content can be children of a folder or Smart Folder and can be filtered with Content Query and sorted. Top and Skip also can be set. For all available settings check the Properties section.

Content collection Portlet properties

Context binding

Content collection Portlet is a context bound portlet. This means you can (and have to) define a context to work with. This is by default the current folder or other container that the user is browsing but you can select any other container in the Sense/Net Content Repository.

Content to display

By default the Content collection Portlet displays the children of the current context. Direct children are shown if the All children property is unchecked, otherwise every content in the content repository below the current context will be displayed. You can provide a Content Query as filter (for example only content of type Article and the ones that were created this week). SystemFolder contexts are special cases in the sense that content under SystemFolders will never be displayed unless the Enabled autofilters is switched off.


If you want to enable paging you have to set the following two portlet properties:

  • Enable paging
  • Show pager control

For a brief description of ASCX views see the section below about collection views.

For more information about paging see the paging section in the article Collection View


Be aware that caching is switched ON by default on content collection portlets. If you want changes to take effect immediately (after adding new items for example) please switch caching off.

Sort descending SortDescending Sort results by sort field ascending or descending
Show pager control ShowPagerControl Set to true to show default pager controls at the top and the bottom of results
Top Top The first given number of content are listed
Uri parameter name UriParameterName The Uri parameter name to use as external source
Visible fields VisibleFields A comma separated list of fields presented in the list

Inherited properties

User interface

Property Property name for embedding Possible values Description
Portlet title Title text Sets the visible title of the current portlet. Title header visibility is controlled with the Appearance property
Appearance ChromeType Default
Controls title and border visibility. By default both are visible
View Renderer Repository path A custom view to render te portlet. Can be an ASCX file or an XSLT.
Custom CSS class(es) SkinPreFix text When set portlet container div gets an extra css class. Ie. 'skinexample' adds css class 'skinexampleSkin' to container div

Context binding

Property Property name for embedding Possible values Description
Bind Target BindTarget Unselected
Select the bound content. Set it to CustomRoot to select a content with absolute path regardless of the context
Custom root path CustomRootPath Root relative Repository path Define bound content with absolute path when Bind Target is set to CustomRoot
Ancestor selector index AncestorIndex positive whole number Set the bound content to the ancestor of Bind Target specified by index. 0 leaves the bound content as specified above, 1 selects parent, higher value selects higher order ancestor
Relative content selector path RelativeContentPath relative Repository path Sets the bound content relative to the above settings with a relative path. Ie.: 'CustomChildFolder/CustomNode' selects 'CustomNode' from Bind Target's 'CustomChildFolder' child folder. Relative to ancestor when Ancestor selector index is set
Reference field name ReferenceFieldName text Selects a referenced content of the bound content. Ie.: 'Manager' selects the Manager if the Bind Target above is the current workspace.


Property Property name for embedding Possible values Description
Portlet is cached Cacheable true/false If set the output of the portlet will be cached
Portlet is cached for... CacheableFor VisitorsOnly
In case of 'Everyone' the output of the portlet will be cached for logged in users as well.
Portlet context influences caching CacheByContext true/false Defines whether the current context path is included in the cache key. When unchecked portlet output is preserved regardless of the page's current context content or request path. Check it if you want to cache portlet output depending on the requested context content.
Request path influences caching CacheByPath true/false Defines whether the requested content path is included in the cache key. When unchecked portlet output is preserved regardless of the page's current context content or request path. Check it if you want to cache portlet output depending on the requested context content.
Url query params influence caching CacheByParams true/false Defines whether the url query params are also included in the cache key. When unchecked portlet output is preserved regardless of changing url params
Language influences caching CacheByLanguage true/false Defines whether the language code is also included in the cache key. When unchecked portlet output is preserved regardless of the language that the users use to browse the site. If set, a different output will be cached for any language the users visit the site on.
Sliding expiration SlidingExpirationMinutes positive whole number Given in seconds. The portlet is refreshed when it has not been accessed for the given time period
Absolute expiration AbsoluteExpiration positive whole number Given in seconds. The portlet will be refreshed periodically with the given time period
Custom cache key CustomCacheKey text Defines a custom cache key independent of requested path and query params. Useful when the same static output is rendered at various pages.
Debug Debug true/false Check this property to show debug info about portlet cache state at the bottom of the portlet's layout

for Portal builders

The easiest way to use the Content collection Portlet is to place it onto a portlet page. For more details check the following article:

Content collection views

Collecting the list of content is only the first part. To display the items you need to create a collection view. Sense/Net ECM system provides default collection views that you can use as a starting point.

  • /Root/Global/renderers/ContentCollectionView.ascx
  • /Root/Global/renderers/ContentCollectionView.xslt

XSLT views

Collection XSLT views are built upon an XML that the Content collection Portlet provides. You do not have to do anything about the xml; the portlet automatically provides it if you choose an XSLT view on the portlet properties window.

The XML provided by the portlet contains all the fields and actions of the listed content by default. You can fine-tune this by setting the Fields, Field list or Actions properties of the portlet to improve performance.

For more information about XSLT rendering check this article.

ASCX views

Ascx views are common ASP.NET user controls inheriting the ContentCollectionView class. They have access to the list of content provided by the portlet and have full control above the rendered html.

<%foreach (var content in this.Model.Items)
  { %>
    <div class="sn-content sn-contentlist-item">
        <h1 class="sn-content-title">
            <%if (Security.IsInRole("SmartEditors"))%>
                <%= Actions.ActionMenu(content.Path, "[SN]", "ListItem") %>
<%} %>

Paging can be implemented by a code snippet inserted above or below the displayed content:

<%foreach (var pageAction in this.Model.Pager.PagerActions) {
            if (pageAction.CurrentlyActive) {  %>
                <span class="sn-pager-item sn-pager-active"><%=pageAction.PageNumber%></span>
            <%} else { %>
                <a class="sn-pager-item" href="<%=pageAction.Url %>"><%=pageAction.PageNumber%></a>
            <%} %>
<% } %>

For more information about collection views check this article.

Page template and control embedding

Use the following markup if you want to embed the portlet into your Page Template or custom control. The attributes/options are the same as seen in the Properties section above (don't forget to include a unique ID and the runat="server" attributes).

<snpe:ContentCollectionPortlet Title="Main Menu" ChromeType="BorderOnly" 
   BindTarget="CurrentWorkspace" Renderer="/Root/Global/renderers/MenuCollectionView.ascx" 
   SortBy="Index" ID="MainMenu" runat="server" />

for Developers

Content collection Portlet defines behaviors and features that can be re-used in your own custom portlet that is related to displaying multiple content. For more information about developing a custom content collection portlet check the following article:
