I am using asp.net and I need to display a prompt to the user if they have made changes to the web page, and they accidentally close down the browser.
The page could be anything from "Edit Profile" to a "Submit a Claim" etc.
How can I can display the messagebox, ensuring that it is displayed only if changes have been made (as opposed to, the user making changes, then undo-ing the changes, and shutting down the browser)
Currently I have the text file going to desktop, in ASP how can I prompt a file save dialog for the user? The result is string from the streamreader as "result" as follows:
StreamWriter FileWriter = new StreamWriter(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "file.txt"));
FileWriter.Write(result);
FileWriter.Close();

View 1 RepliesMy situation:
i have a web form to let user export the file. It will prompt a save dialog to let user choose where they want to save the file.
So after user click the Export button, there are 3 things must be done at the same time :
(1) Prompt save dialog
(2) Refresh the Page
(3) Pop up a windows to show the crystal report
I have already done the (1) and (2) but how can i do the (3)?
I'm trying to write code that will allow a user to click a button and be prompted to save an image file that resides on the web server. I'm using the following code, but I get an error that says "Error: Could not complete the operation due to error c00ce514.".

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.

I have a reorderlist hooked up with database. I want myself to reorder the stuff in it. Rather than posting the page back everytime when i reorder the stuff, I should be able to make all the changes in my database on button click.
(Basically I dont want my page to post back everytime when I reorde, all the changes made to the list should be commited at the end when Button is clicked)
I 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 detailsview in insert mode. I want to prompt the user to enter data in all fields, if left empty. Could someone please find a few minutes to show me how to do it?

I have to warn the user when leaving the gridview row in edit mode without saving or cancelling the data. How can I achieve this? I have a javascript function which simply prompts the user when he/she leaves the screen which is not serving the purpose.

View 1 RepliesI'm working on a project in which we have a database, data layer (entity framework), business layer and web/UI layer.I want to use ASP.NET Dynamic Data for the web layer, but don't want it to access the data layer or database, as I want it to be purely running off business logic, and not directly accessing the data.However, it appears that Dynamic Data only allows Linq-to-SQL or entity framework data sources to be used.Has anyone used it with business-layer objects instead?

Query 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?

View 3 RepliesI'm trying to edit an aspx page...mainly javascript, and I randomly see changes that I've made when refreshing.
I'm using jquery, but I'm not sure that jquery is the culprit here.
For example. If I add a simple alert("hello"); in the page I'm calling, I do not see it take place until I have cleared all my temp files and cache, closed my browser opened back up...and even then, sometimes, I still don't see my changes.
Before you recommend any of the other posts I have viewed to resolve this, let me this them here:[URL]
