Web Forms :: Disable Button After Validation But Before Post Back
Mar 29, 2010
I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these asp.net validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?
C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
Button
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
alert(group);
My problem is when I use ASP.net, this button do PostBack, but I not need this because my list of items then gone. How can I override this behavior of button.
I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway.
My customer has a website that is unsuitable for children. Anyone under 18 is not allowed ont he site. No, it's not a porn site, it's prison related. A certain page requires the user to enter their birthdate. If they are under 18, they're redirected to another site.
He has another site written for kids who have been impacted by crime. He wants the kids redirected here, to a page that explains why they were redirected. He asked me to disable the back button at this point to keep the kids from easily going back to the original site.
I've read all the reasons why you shouldn't desable the back button, but frankly, I think this would an appropriate place to do it. I also know you really can't disable it, but I've found a number of work arounds - none of which I've gotten to work.
Is there a work around that will work?
I've thought of setting a session variable or a hidden field or an invisible label on the page that redirects the kids just before the redirect and checking the value at page load, but the code to do the checking doesn't get run unless the user hits the back button then refreshes the page. Is there a way to get code to run as soon as the back button is pressed?

I have a shopping basket on my site, and when the customer gets to the final page I don't won't them to be able to go back i.e. use the back button on the explorer. I have seen it before on other web sites, it's like when you leave the page it 'times out'I am just not sure how that works.

After user has logged out i am redirecting user to home.aspx and from here i do not want user to be able to go back using browser back button.. How can i do it? I used this code in javascript :
My problem is when I logout from my website, the logout button redirects to login page , and then if I click BACK button in browser, I can go back to my website. I do not want that.
What I am actually trying to make is like at mail.yahoo.com or at mail.google.com after sucessful logout user cannot view the account.
I would like to make the same functionality for my application.
I have read that you can not disable the back button on page load but I can clear the cashe on page load so the back button would then be greyed out. I have read a few articles on this and I am unable to get it working. I am using MS visual web developer 2010.

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I have developed some aspx pages using visual studio 2008. I am authenticating using Active Directory services. I have kept a link button on my aspx page which says signout .What exactly i want to do is that i want the back button of my login page to be disabled so that when i press signout and when my login page loads users cant go back and thus forced to enter the login details. I am using c# as development language.
I'm using 2 masterpages in my project.One master page is for login page and another one for the HomePage where user will go thro the options to reach other pages from home page..The thing is,i have "Logout" button in my home page.When i click on the logout button,the page will be redirected to "LoginPage.aspx".
