Force The ASP.NET Page Lifecycle To Go Forward?
Mar 29, 2012
I am working on a custom framework above the .NET framework, and some instructions are not written / called at the good places.
For example, a postback is done on the same page. Then, a Response.redirect occurs right within the page_load; but at this point, the new values of the controls of the page are not yet handled, so they get lost...
Therefore, I wanted to know whether it was possible to force the pagelife_cycle to go forward before the call to response.redirect, so that I can get the right values.
I can't just make that call in another function, because the page I am working on is called by many web applications (about 1-2k), and it would completely change their behaviour, which is not acceptable!

Clicking on a link button on a page causes Postback to a page containing a number of controls. [code]During the Postback to (page a) on the server, (page d) is requested when using the IE browser (doesn't happen in Firefox) there are absolutely NO artefacts requested that live on (page d), there are no response redirects or server transfers or anything referencing (page d).The only thing I have seen like this is when an image or artefact is requested and cant be found, or some pathing issues for an image, and this somehow screws the request up.

I have an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.

I have a web app that has a base page.Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights.My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed.On the init of each page I set the properties "Role1Allowed" and "Role2Allowed".[code]Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was?As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it.Is there any way to force them to do this?

I've got a handful of dynamic controls populating an ASP page, with VB.NET in the back-end.What I need is when the user changes the .TEXT value of a textbox and the page posts back, the .TEXT value of a Table Cell changes to reflect that change (it multiplies the value of the textbox by the value of another cell).But a Table Cell can't be set to AutoPostBack, and I can't for the life of me figure out how to programmatically refresh the page (force a postback) in the TextChanged event for the textbox.

I'm printing a multi page document with PrintDocument() and I need to be able to force a page break from within my code. I've tried adding vbFormFeed at the appropriate spot but it's ignored.
Is there any way to embed something into my page buffer so that it will force a page break?

I have an ASP button for which I have set the OnClientClick property to display a javascript confirm message. However, I only want this message to be displayed AFTER all of the client side validations have passed. How can I do this? Essentially, I believe that I need to force Page level validation from the client and then, only if it passes, display the confirmation box.

I have a requirement to print a number of records from a database. Each record refers to a second database that holds x number of related records. Just like and invoice header and line items.
I first print the report heading on the first page Something like "Invoice list for May 2012"
I then print the Invoice record headings under the the report heading Something like "Inv# Cust # Cust Phone Address 1 Address2 etc"
I then print that data from the original recordset Something like 1234 DR127 555 555-1212 Somewhereville 245th street
I then print the Line item headings Something like "Ln# Item# Description Qty Cost Selling Extn"
NOW Here is my problem: I never know how many line items there will be so can not predetermine when I will need a new page. I do have a way of telling when I am at the bottom of a page by using the text height and incrementing a value for each line
BUT I cannot figure out how to break out of the line item loop, start a bew page then carry on where I left off.
Once all the line items have been printed I need to start the next invoice by printing the Invoice record headings again followed by the header data followed by the line item headers followed by the line items for that invoice.
I have said that the page break may come while in the line item loop but it actually cold come anywhere in the overall loop.

I want to use webbrowser to go to a web site. This web site has three possible screens that I can get when I try to visit:
(1) A fresh login page, where it does not seem to know me and asks my name and password
(2) The main page of the site, with me logged in from my last visit
(3) A screen that says something like: "Thanks for visiting and logging out. click here to log back in."
I want to make it so that the webbrowser 1 ALWAYS is able to get to the first kind of page. When I have webbrowser1 navigate to the specified URL I want it to *not* be redirected to already being logged in from last time and to *not* be redirected to the third kind of page.
I am trying to make a program so that it goes to the site, enters my username and password, and clicks the "login" button. This is getting messed up because it does not always go to the first kind of page, and, actually, most often redirects to the second or third screens, to my aggravation!
Is there some command I can use with webbrowser and my visual basic 10 program to make it so the webbrowser is NOT redirected without me wanting it to be, so that it always goes into the "fresh" login page?

One thing I don't understand with sending Async emails from ASP.NET page is when we call SendAsync it should be executed on a separate thread so our page can continue its execution flow and finish its response no matter how long the sending will take.How then we can call method on the same page using SendCompletedEventHandler? The page object might not exist by that time and in this forum there are examples that people doing that.My expectation was that I can have separate class which might have static method which I will execute on SendCompletedEventHandler and this way we can report possible errors.However when I'm raising exception in there the exception comes as part of Page Response. So for me it looks as SendAsync works on the same thread, page waites for it to be executed and comes back with information on any errors raised by it.

I'm having trouble coding some new items into a program of mine. The program loops through you Inbox looking for emails that are UNREAD and have a certain subject line. The subject line in this case, is going to search for: "FAX TO: ###########" (actually, it just searches for FAX TO). Next step, I need the selected email to be FORWARDED to the fax number in the subject line - including attachments. In my code - I've already got the message selected - but I can't figure out how to programmatically forward it? I need explicit code help with the following:
1) Check to make sure there are 10 digits in the original subject line. If not - bail out and ignore that message.
2) Trim the subject line and save the phone number to a string
3) Forward the message (plus attachments) to the [URL]
I'm assuming I'll need to create a new Outlook.MailItem, but I'm not sure if I need to. Is there just some code I'm missing so I don't have to COPY the contents of the current MailItem to a new one.

I'm trying to set up a WebBrowser control so that it will respond to the user pressing the mouse's Forward or Back buttons and navigate accordingly, regardless of where the cursor is located in the form. The WebBrowser control doesn't have any click event handlers, and I couldn't add one with AddHandler, so I'm not sure what to try. Searching here, I read about GetAsyncKeyState which can be used to get the status of the mousebuttons, but I don't know how I would use this to code an event handler for these buttons.

How could I make it where I could accurately go forward and backward? Whenever you press back once, then back again, it takes you to the page you started with. So how do you make it where it can go back as many pages as there are and then tell if your a the highest or last page when going forward?
