Hi,

I have a module with a control (let's call it "Print-Control") that calls a class method that dynamically creates a PDF and sends it by a memory stream. This class is defined in a seperate file (under "Components"). Here is the relevant code:

MemoryStream stream = new MemoryStream();
// Some code that saves the document to the stream left out...
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ContentEncoding = System.Text.Encoding.Default;
response.HeaderEncoding = System.Text.Encoding.Default;
response.ContentType = "application/pdf";
response.AddHeader("content-disposition", "attachment;filename=Test.pdf");
response.AddHeader("content-length", stream.Length.ToString());
response.BinaryWrite(stream.ToArray());
response.Flush();
stream.Close();
response.End();

Works fine so far... As the module is a bit old (originally written for DNN 4.6 or so) and I am about to "modernize" it (in the way of using newer methods from the DNN Framework, applying the UX foundation etc.) I tried to change this control definition that it supports pop-ups. But when it is in a popup, the last line fires an exception ("Thread was aborted"). Any idea why and how I can avoid this (apart from defining this control to not support popups:-))?

Happy DNNing!
