Add a Comments widget and Comments counter in a template

You can manage the comments in your website with the built-in CommentsWidget and CommentsCountControl. 

PREREQUISITES: To use the CommentsWidget and CommentsCountControl widgets, in your template you must add the following reference:
<%@ Register Assembly="Telerik.Sitefinity" Namespace="Telerik.Sitefinity.Modules.Comments.Web.UI.Frontend" TagPrefix="comments" %>

• ThreadKey property
  To use the widget, you must specify its ThreadKey property. When you set the ThreadKey property of the CommentsWidget you ensure that the comments submitted in this CommentsWidget are stored in a specific thread. This allows you to have more than one Comments widget on the same page and they display different comments. To do this, set two different ThreadKeys to each widget. This is useful, if you want to allow the users to comments different items displayed on the same page. 
  

  By setting the ThreadKey, you ensure that for every translation the CommentsWidget is associated with different threads. This way you can have different comments for the different translations of your items. 

• GroupKey property
  You can set the GroupKey property of the CommentsWidget. This way, you can specify the group that is associated with the thread. 
• ThreadType property
• You can set the ThreadType property of the CommentsWidget. This property associates the widget with some item type. Then, you can control the thread settings by clicking Adimistration » Settings » Advanced » CommentsModule » CommentableTypes.

If you do not set the GroupKey and the ThreadType properties your CommentsWidget is automatically associated with the current page. Sitefinity CMS creates a new thread for this CommentsWidget when the first comment is submitted. In this case, if you drop two CommentsWidget on the same page they display the same comments. 

NOTE: If you want to have two different items with the same list of comments, you can set the ThreadType and GroupKey for both CommentsWidgets to the same values.

Sitefinity CMS has a separate widget that displays the count of the comments associated with particular thread.

  • DisplayMode="ShortText"
