There is a Submit button on Order page.
Due to network traffic, sometime user clicks Submit button more than one time and cause a duplicate data was inserted.
How to void multiple submission in code page?
I am looking for a way to figure out the current URL that the page is currently on (NOT what the asp.net page currently is, but where the CODE is at). ie. My web app is located at: [URL] my code is: String page = [URL]
String response = GetResponse(page); //basically the above code goes to the website [URL] and parses the HTML within it and brings it back and populates the variable string "response". But, sometimes the [URL] throws me a curve ball and redirects me to: [URL] I want to be able to use a try/catch to be able to "catch" the error of a different page: ie validateUser.aspx. So, I need to do to this: try
{
String page = [URL];
String response = GetResponse(page);
}
catch
{
//code to check the behind URL to see if [URL] is the URL OR IF [URL] is the current URL
}
understand I know how to find the URL of the current page the web app is on. I need to find the current page that threw the exception during the execution of the code behind.
I was able to find examples throughout the internet that more or less accomplished what I needed to be done, but now I have run into some problems. I need to be emailed the form data when the users submits it and then the user needs to be redirected to a thank you page, in this case "thanks.asp". I have been unable to get the form to redirect users to the thanks page, and in my efforts I think I might have messed the email process up as well.

I am having problem with multiple clicks on submit button. Multiple clicks cause duplicate record insertion in database. On the form, I have used validation controls. Also I have to make some validations at server side, so I can't use javascript to prevent multiple clicks.
View 15 Replies1. I want to stop multiple clicks on a submit button. Once the user has clicked the submit button,he has been redirected to next page. but he should not be allowed to click submit button multiple times.
2. once the user has gone to the next page, he should not be able to come back to previuos page,; if at all he comes back-- all the form fields should get cleared. how?
An outside vendor did some html work for us, and I'm filling in the actual functionality. I have an issue that I need help with.
He created a simple html page that is opened as a modal pop-up. It contains a form with a few input fields and a submit button. On submitting, an email should be sent using info from the input fields.
I turned his simple html page into a simple aspx page, added runat=server to the form, and added the c# code inside script tags to create and send the email.
It technically works but has a big issue. After the information is submitted and the email is sent, the page (which is supposed to just be a modal pop-up type thing) gets reloaded, but it is now no longer a pop-up. It's reloaded as a standalone page.
So I'm trying to find out if there is a way to get the form to just execute those few lines of c# code on submission without reloading the form. I'm somewhat aware of cgi scripts, but from what I've read, that can be buggy with IIS and all. Plus I'd like to think I could get these few lines of code to run without creating a separate executable.
I have a public void procedure, which is on my master page, and I need to be able to call this from aspx page as it is common to a number of pages that will use my master page. How do I do this?
View 12 RepliesEver since we have moved to the 4.0 framework one of my apps now reports errors when users enter punctuation into the form. Which is a good thing, I do have a function in place that replaces all apostrophes with a double apostrophe but decided to beef it up by applying the httpUtility.htmlencode to the textboxes before I send it to a confirmation page that then emails the page to me and the person submitting the form. The problem is that the checks I have put into place to sanitize the textboxes don't fire because the 4.0 framework stops the submission dead in its tracks before the code can be ran. I have set the ValidateRequest="false" in the page tag but still no luck in getting sanitization to run. Is there something I am missing? From all I have read it should have worked.

View 1 RepliesI am building an app and am newish to programming. I am having issues with the ICallBack. Basically on my .aspx page i will have lots of gridviews in repeaters,and i need some javascript to cycle through those and change the colours accordingly after it has done a function.This code worked fine on my laptop,but when i uploaded it to our server it stopped, apparnetly MS have changed something from early .net 2 to .net4.To get my code not to throw an error i have made a new public void
public void RaiseCallbackEvent(String eventArgument){}
and put my code in here, the problem is that in this public void, i connect to the DB grab data into a datatable and then fill various gridviews, however i cant get it to fire as its not in the onpageload part of my code.I read that if i was to add System.Web.UI.Page, Page, ICallbackEventHandler- this to my code it would work, but it doesnt, it just throws an error.
I get the error above when tryin to call the AddTobasket method. (Cannot implicitly convert type Void to String).
Here is my code.
[Code]....
Let's say I have the following;
public static void TryOut(int intOne, int intTwo, string strone, string strtwo){....}
And after I created dll, I will use it like that;
TryOut(1,3,"bla bla bla", "bla bla bla");
But I want the last variable to be optional. I mean this method could be used like that;
TryOut(1,3,"bla bla bla", "bla bla bla");
And Also like that
TryOut(1,3,"bla bla bla");
I know it is possibel but how I could do that I have no idea !

View 2 RepliesI am using C# & mvc and have an aspx view page where I am trying to use inline code to set the style of a div elemnet:

But when I type the inline code in I get the error
"Cannot implicitly convert type 'void' to 'object'".
Whereas some of the Attrbute methods work fine like
<%= MyDiv.Attributes.Count %>
What is the void it is refering to, is it possible to set the styles like this inline,
