Hi,
I'm trying to achieve the same as asked in Q232026: start a file download in the browser as a result of a user pressing an action button. The code below execute OK and then I get an error message : "Thread was being aborted." Do you have any tips/tricks/code to avoid this problem?
private void PushFile(string fileName, string type, string tempFileName)
{
//Push file to the user by placing it in the response
HttpContext.Current.Response.ContentType = "application / x - msdownload";
HttpContext.Current.Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", fileName));
HttpContext.Current.Response.WriteFile(tempFileName);
HttpContext.Current.Response.End();
}
regards,
Martin

Hello Martin,
Since you are now using 11.2, please set the IsPostBackRequired property for your Action to True as described at the end of eXpressApp Framework 11.2 ASP.NET Application Migration Guidelines.
If this does not make any difference, please provide us with a small sample project that demonstrates your issue.
Thanks,
Dennis
Hello Martin,
When the IsPostBackRequired property is set for the PopupWindowShowAction, this affects only the click that shows the popup window. So, this setting will not provide any benefits in your situation. The window is closed via the DialogOK action, so you need to set the IsPostBackRequired property of this action to raise a PostBack when the dialog's OK button is clicked. The file is downloaded correctly after this.
Thanks,
Anatol
