I recall from previous development that there are problems creating a "download" function in a module in DNN if the Support Partial Rendering is enabled for that module. One solution to this is of course to disable Partial Rendering for that module, but is there a way to get it to work with Partial Rendering enabled? Is it possible to programmatically disable this temporary just to get the download to work?

This is the current solution we use to send files to the client, perhaps there is a better way? Please note that files are created dynamically.-

public static void SendBinaryFileToClient(HttpResponse response, Byte[] stream, string contentType, string fileName)
{

response.Clear();
response.ClearContent();
response.ClearHeaders();
response.ContentType = contentType;
response.Charset = "UTF-8";
response.AddHeader("content-disposition", String.Format("attachment;filename={0}", fileName));
response.AddHeader("Content-Length", stream.Length.ToString());
response.BinaryWrite(stream);
response.Flush();
response.End();

}

Patrik,

you can disable partial rendering for single controls, thats the way I do it. E.g.

protected override void OnInit(EventArgs e)
{
   ...
   ScriptManager.GetCurrent(Page).RegisterPostBackControl(DownloadFileButton);
   ...
}

Happy DNNing!
Michael
