    I have a control called: NewsView1 and I' below is what I'm using for filtering the news items.

            ContentFilterBuilder filter = new ContentFilterBuilder(NewsView1); 
            ContentManager contentManager = new ContentManager(); 
            if (category != null && category != "") 
                filter.AddFilter(new ContentFilterStatement("Category", category, ContentFilter.Condition.Equal)); 

    Can someone please advice, how to get the count of items after filter has been applied.

    thanks in advance.

    Hi Zahid Ali,

    You  have to create a custom control, not an user and inherits from NewsView. Then override CreateContentList() and call SelectContentCount() which will return the number of the items. Another option is calling GetContent right after the filtering and use Count to check the items in the list.

    Best wishes,
