How To Avoid Form Resubmission
Sep 21, 2010
I'm developing ASP.NET applications and stuck with a "problem" relating to resubmit behaviour. I'm controling the re-submit using a counter in form submit event which disables the submit if it's already been posted. My application is a 3 step workflow and when the 3rd step is shown the transaction was submited from step2 to step 3. What's my problem? Well... i want to avoid the user to resubmit the data by pressing the F5 or all other possibility. I don't want to disable the key because may be workarounds. I'm wondering if i can remove the post data in a HTTP module that runs after the render was completed and right before the response is sent to the user.

My ViewState implementation causes "Confirm Form Resubmission" dialog to appear each time I press 'back' button, but when I create test site using microsoft's aspx their viewstate isn't causing such problems. What should I know to prevent my browser from showing "Confirm Form Resubmission"? I've found an interesting resource here, the problem described in terms of browser caching, if the page is cached than it won't make a post at all, now it is interesting how to make my page cachable by default.

I have a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?

I recently noticed that I had a big hole in my application because I had done something like:
<input type="text" value="<%= value%>" />
I know that I should have used Html.Encode, but is there any way to do that for all values, without having to do it explicitly?

im using sql server 2008
as per microsoft, [URL]
when i execute the following
set identity_insert on
//insert statements here
set identity_insert off
the identity of the column is set to the maximum value. can i aviod this.
consider the following scenario,
my table has 2 rows as follows
id, name comm
1, John, 232.43
2, Alex, 353.52
now using the above code, when i insert
10, Smith, 334.23
as per the above link, sql server automatically sets the identity to 10. so for newly inserted records(without using identity_insert on), id automatically starts with 11.
i want the identity value to be 3, after using identity_insert on/off

I'm have a page which I sent a parameter through the query string.
If I'm retrieving it with Request.QueryString["Format"] I'm having troubles with the type 'CDDVD'. It's being returned as 'CD\DVD'. It's important I get this as the right string.
How do I avoid the extra backslash? Or even get rid of it later?

I'm working on a website powered by .NET asp/C# code. The clients require that sessions have a 25 minute timeout. However, sometimes the site is used, and a user stays connected for long periods of time (longer than 25 mins). Session_End is triggered:
protected void Session_End(Object sender, EventArgs e)
{
Hashtable trackingInformaiton = (Hashtable)Application["trackingInformation"];
trackingInformaiton.Remove(Session["trackingID"]);
}
The user returns some time later, but when they interact with the website, they get an error, and we get this email notification:
User: Unauthenticated User
Error: System.Web.HttpException
Description: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request...
The telling part of the stack trace is System.Web.UI.Control.AddedControl. Apparently, the server has thrown away the session data, and is sending new data, but the client is trying to deal with old data. Hence the error that "the control tree into which viewstate is being loaded [doesn't] match the control tree that was used to save the viewstate during the prevoius request."
So here's the question. How can I force instruct the user's browser to redirect to a "you're logged out" screen when the connection times out? (Is it something I should add to the Session_End method?)

I am working in a school and we recently installed a new server running WinServer 2008R2. I want to be able to point people to a URL on our intranet and have them fill out a simple registration form and have this data written to a database. It would also be nice to have some data auto-populate (such as their name).
Is it overkill to set up a sharepoint server and try to do this with Access Webforms? Could I use something like dotnetnuke and find a module that works? Or how about options for writing custom forms?

I have a page with a ScriptManager / UpdatePanel. I currently need to PostBack to a https page from an http page (different ports). I also need the same session data. Currently, I copy my form to a new form, and when I postback to my new Target on a new Port, I get a crash in xmlHttp..something. I will have to post more details later.
I'm currently wondering if this is possible. And does anyone know of such a fix. I even tried to Turn off Partial Rendering and I still get crashes. I can't do this until I pull out the scriptManager / UpdatePanel.

I know this is a very common problem and a quick search in google offers a lot of solutions. However I could only find one person that came across it in the same way I am and no-one answered their question.
The scenario which causes this is if the page has been left dormant for a period of time and then a button is pressed which runs some sort of command. This might be pressing the logout button or trying to submit a contact form after having walked away at some point and then returning and hitting Send.
I do not have posts or actions in my form, it looks like this: <form id="form1" runat="server">
I have also added the following line to my web.config: <pages enableEventValidation="false" iewStateEncryptionMode="Never">
