I have verified that the file exists. Is there another method for prompting users to save a file to their local machine?
A friend of mine gave me this task so I can learn advance programming a little bit easier. I am currently doing convertion of an html page to pdf using itext sharp and email the pdf as an attachement. My idea is to save the pdf first to the server machine in the folder name ToBeEmailedPDF folder before using it as an email attachment. The thing that bothers me is that this dialog as what you can see in the picture shows up using the code that I have below.

Does anyone know how this is possible? I can retrieve the file, but I cannot figure out or find anywhere online how to prompt the user where he/she wants to download the file to.
View 2 RepliesI am building an application that allows a user to upload multiple images, resizes them, and saves them. What I need (ok, what I'd like) is the following...
I would like some sort of way to prompt a user to crop the photos after they have been saved. I have code that creates a 175px square rectangle and saves that image. I need the user to select the image section they want saved and to do so I envision a window that automatically prompts them to do so once the upload(s) have completed. I think my preference would be to have a page or control (datalist, repeater, ectc..) that refreshes every time an image is saved and allows the user to crop the newly saved images. I'm opened to advice, opinions, free drinks and a clue.

I have a webpage that allows a user to download a specified file. When the file is ready to be fully downloaded (i.e I call the HttpResponse.End or HTTPRepone.Flush) the user is presented with a File Download dialogue.
Is there any way to determine what option the user has selected?
Have they Opened, Saved or Cancelled the File Download once the Flush or End has been sent?
I have a user control (ascx file) that contains an interface for users to change the data retrieved from the db. So, I am displaying data and most of this data can be edited by the user. When the user enters text into a textbox, and clicks "Save Changes", the value they typed in is lost and not persisted to the database. I realize now this is because the SaveChanges button does a postback, and the user control gets reloaded with its original valuesbefore the code within my SaveChanges button gets executed. I'm not sure if there are properties I need to set to save the input data, or if I need to write my own code to do it. What is the generally accepted method to do this? (Also, all of the controls in the ascx file are wrapped in an Update Panel.)
