View 8 RepliesI've a page main.aspx. This page has a button 'Settings'. When it is clicked, I load another aspx page settigns.aspx in a popup. Now in the settings.aspx i allow the users to add controls dynamically. For example the user can create 5 textboxes. When he saves it there, I need to get that controls to main.aspx.
So i need to move all the controls from one page to another page. I'm not able to think of a solution with user controls.

Cause I have a gridview that use an sqldatasource and in the UpdateCommand I want to include a the session variable : session("username").
Ex :
UpdateCommand="UPDATE departments SET DEP_name = @DEP_name, DEP_active = @DEP_active, DEP_date_stamp = CONVERT (CHAR(8), GETDATE(), 112) + ' ' + CONVERT (VARCHAR(8), GETDATE(), 108),
DEP_user_stamp = <% session("username") %> WHERE (DEP_mnc = @original_DEP_mnc)">

Building asp.C# shopping app that is using a hosted payment page to process payments (using posting of data to a hosted payment page). SSL certificate is signed and installed.
Flow:
Prelim) (HTTPS) Users authenticate using asp Login control
1) Users add items to cart.
2) (HTTPS)Users go to checkout page.
3) Users finalize their order, then click pay now after agreeing to T&C.
4) Server gets cart data (from MSSQL2005) and sets a transaction cookie (expiry set to 20 mins).
5) (HTTPS) Server Response.Redirects to an html page (in the same folder as the login protected pages).
6) Html page reads transaction cookie data and generates form fields.
7) (HTTPS) Html page posts data to hosted payment page (php).
8) User enters payment info and clicks pay now.
9) (HTTPS) hosted payment page posts info back to a .aspx page that checks if payment OK.
10a) If payment !OK, redirects to a declined page.
10b) (HTTPS) If payment OK, sets a verification cookie (expiry set to 20 mins). Then redirects to another html page.
11) Html page reads cookie data and generates form fields.
12) (HTTPS) Html page posts data to hosted verification page (php).
13) Verification page verifies (of course), if transaction ok.
14) (HTTPS) verification page posts data to a .aspx page that checks if verification OK.
15) If verification OK, process orders and do receipt stuff.
Issue:
This control flow was tested on an unsigned dev environment. SSL was being enforced, if needed on the unsigned SSL certificate. So we'd get prompts that certificate may be bad, but the control flow worked seamlessly.
However, now live with a signed SSL certificate, going from step 5 to 6, we are encountering a situation where some users (not duplicated every time, but verified that it does occur) when they click pay now and are redirected to the html page, they are forced back to the ~/login.aspx page (as if they were logged out).
Things to note:
a) The session did not time out.
b) The browsers have cookies and javascript enabled.
c) I can process the entire flow seamlessly on the same machine with other accounts, and occasionally, the same account.
So, basically, I'm stumped... Is this a viewstate error? A login control bug that won't let me redirect to an html page because it is now using a real SSL? Anyone have any experience with this kind of deal? I'm at a loss for solutions at this point.

View 2 RepliesAll the examples and websites i have looked at redirect a user to the error.aspx page when an error occurs. How do you just display a friendly error message on the page the user is viewing saying something like "Sorry unable to do whatever" I've tried using a try catch block on my class that executes a stored procedure and put another try catch on the controller, but this does not work and i still get the default error message (System.InvalidOperationException was unhandled by user code) My code is below:

Here is what I am trying to do in ASP.NET:
Create one page called Main.aspx. This page has a DIV and a buttons.
The browser loads Main.aspx. Then when I click the button, I want to load page Page99.aspx into the DIV in Main.aspx dynamically, but without Main.aspx requiring a postback.
So, Main.aspx loads once, and thereafter all the content displayed in Main.aspx will come from different .aspx pages.
Ps. I'm looking for a solution as above, but not using frames.
UPDATE 1
I should mention that Page99 is not a simple HTML page. It will contain Web controls.
I want to display all the session information of my asp.net page (aspx) in the page. How can I do that? The programming language is C#.
View 2 RepliesI have a aspx called user-photo-upload.aspx and another aspx called get-photo.aspx. I set the Session["PhotoId"] in the page_load method of user-photo-upload.aspx.
If I visit the user-photo-upload.aspx through the browser normally, the session can be retrieved in get-photo.aspx. But if the flash uploads photo to the user-photo-upload.aspx page, I can't get the Session["PhotoId"] in get-photo.aspx.
I discover that the Session ID is different when visiting the page using browser normally or by flash. I don't know why flash uses another session.

I have an webforms app that loses it's session variables on response.redirect. I've read Bertrand Le Roy's blog about this and still can't get it to work. The page works in production. However, when I try in the VS2k8 IDE, the session variables are there right before response.redirect and on the first line of the next page, the variables are nothing. I've confirmed the session id is the same so I'm not skipping sessions. The target page is relative so the web server doesn't think we're changing sites (as confirmed by the sessionid).
