The problem with Rad Chart is you cannot print it into PDF directly.

Now, solution depends upon the third party tool or dll you use to make a PDF.

Since Rad chart is basically image being shown after rendering, you have to call the image using e.g. <asp:image runat="server" id="imgTest" ImageURL="Test.aspx" />.

Now in Test.aspx:

    public void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
                MemoryStream imageStream = drawChart();

                Byte[] imageContent = new Byte[imageStream.Length];

                imageStream.Position = 0;
                imageStream.Read(imageContent, 0, (Int32)imageStream.Length);
                imageStream.Close();

                Response.ContentType = "image/jpeg";
                Response.BinaryWrite(imageContent);
        }
    }

    private MemoryStream drawChart()
    {
        RadChart chart = new RadChart();

        // Do the necessary coding in order to generate the chart.
        //If more than one chart is being used call the same page with necessary inputs to generate a new image.

        MemoryStream mStream = new MemoryStream();

        chart.Save(mStream, ImageFormat.Jpeg);

        return mStream;
    }

I think it will solve the problem...if authentication issues doesn't arise.
