Answer 1

I would suggest create one .aspx page or HTTPHandler then override ProcessRequest method.

public void ProcessRequest(HttpContext context)
{
   //database table or PDF/word file
   System.IO.MemoryStream mstream = GetData(); 
   //Convert the memorystream to an array of bytes. 
   byte[] byteArray = mstream.ToArray();         

    string fileName= "test.pdf";
    context.Response.Clear();

    context.Response.AppendHeader("content-disposition", "attachment; filename=" + fileName);
    context.Response.ContentType = "application/octet-stream";
    context.Response.BinaryWrite(byteArray); 
    context.Response.Flush();
    context.Response.End();
}

Your Silverlight application will act just like normal client and makes http Request using

<HyperlinkButton Content="Click Me" NavigateUri="Download.aspx?id=fileid" />

in above code

  context.Response.AppendHeader("content-disposition", "attachment;

tells browser to prompt for OPEn/Save dialog.

I hope this will work.
