How to reinitialize dataTables with newly fetched data from server using ajax in MVC

by

The error message http://datatables.net/tn/3 states the problem precisely. You’re re-initializing the table with different options in fetchNews().

You need to destroy the table first, see http://datatables.net/manual/tech-notes/3#destroy.
You can do that with $("#dailyNews").dataTable().fnDestroy() (DataTables 1.9.x) or $("#dailyNews").DataTable().destroy() (DataTables 1.10.x).

function fetchNews(context)
{
     if(context!="")
     {
        // Destroy the table
        // Use $("#dailyNews").DataTable().destroy() for DataTables 1.10.x
        $("#dailyNews").dataTable().fnDestroy()

        $("#dailyNews").dataTable({
           // ... skipped ...
        });
    }
}

Alternatively, if you’re using DataTables 1.10.x, you can initialize the new table with additional option "destroy": true, see below.

function fetchNews(context)
{
     if(context!="")
     {
        $("#dailyNews").dataTable({
            "destroy": true,
            // ... skipped ...
        });
    }
}
