Question

like from a class we return a dataset like this.. values get from a database and bind in grid view or any thing else.

public DataSet GetImgPath()
    {
        try
        {
            conn.Open();
            cmd = new SqlCommand("SelectImg", conn);
            cmd.CommandType = CommandType.StoredProcedure;
            SqlDataAdapter da = new SqlDataAdapter();
            da.SelectCommand = cmd;
            DataSet ds = new DataSet();
            da.Fill(ds);
            conn.Close();
            return ds;
        }
        catch
        {
            conn.Close();
            return new DataSet();
        }
    }

Why do you need to use Handler. You can use PageMethod and call it from Jquery using Ajax
