I'm rendering a Comment control on one of my pages. However, it only displays 5 comments before you have to page to the next 5 comments. How do I increase this page size? There is no attribute or webpart property that I can see

<SharePointPortalControls:SocialCommentControl ID="CommentControl" runat="server" />

I have tried:

CommentControl.Attributes.Add("DisplayItems", "10");


CommentControl.Attributes["DisplayItems"] =  "10";

This should do the trick:

PropertyInfo pi = typeof(SocialCommentControl).GetProperty("DisplayItems", BindingFlags.NonPublic | BindingFlags.Instance);
pi.SetValue(CommentControl, 10);

Valid values for DisplayItems property are 1 through 10. If you set it to less than 1 it will be considered as 1 and if you set it to more than 10 it will be considered as 10.

You could directly access the backfield m_displayItems instead of using the property DisplayItems:

FieldInfo fi = typeof(SocialCommentControl).GetField("m_displayItems", BindingFlags.NonPublic | BindingFlags.Instance);
fi.SetValue(CommentControl, 1000);

This way you can use a value greater than 10 (which is restricted in the property setter).
