I have solved the issue by my self. Hope this answer will save next person time. Below code is working fine for me.

using (WebClient client = new WebClient())
        {
            using (Stream ms = new MemoryStream(client.DownloadData("http://10.70.0.60/PDF/sample.pdf")))
            {
                MemoryStream mStream = new MemoryStream();
                mStream.SetLength(ms.Length);
                ms.Read(mStream.GetBuffer(), 0, (int)ms.Length);
                this.radPdfViewer1.LoadDocument(mStream);                    
            }
        }

You can set Documentsource as shows, Wroked for me

 PDFViewer.DocumentSource = new PdfDocumentSource(new Uri(@"YOUR PATH");
