View 1 RepliesI have a receipt page for my clients that will display their info and they will get notify by an email message. Here is the problem: when user hit refresh button from a brownser, it will send duplicate email message to the user.
This is what i have:
protected
void Page_Load(object sender,
EventArgs e)
{ if(!IsPostBack)
SendEmail()
}
protected void SendEmail()
{ //here is my function for email
}
Situation:
1) Click on 'Check' button and the button will disable
2) Run a processing code(for checking) and once it is done, navigate to a new page(NewPage2).
Here are 2 code situations (1):
[Code]....
and if I do this way (2),:
[Code]....
it will navigate to NewPage2.aspx, but during the execution of the processing code, ButtonCheck control will not be disabled as the Click Event has not finished, and I want it to disable during the checking process. If the 1st option is executed, it will throw to me "Response is not available in this context."? HttpContext is null for (1). In my opinion, I think that the navigation does not recognise the response object as it is in a thread and has exited out of the buttoncheck event. But I'm still not sure why.
how to disable the button and run processing code during the click event and be able to navigate to a new page?

View 10 RepliesI'm building a button in my code behind file and want to bind the click function to an existing click function of a different button. How do I handle this? I was hoping for something simple like:
Button b = new Button();
b.onClick = otherClickEvent();
but apparently that's not doable. Am I missing something here. I'm aware of OnClientClick, but that only deals with the JS side of things apparently.

I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
This is how I tried to implement this:

I have a button which starts processing. I want that when ever a button is click from page1.aspx .. a count down timer should start and displayed on page2.aspx. I am thinking of using iframe to join 2 pages.
View 9 Replies<input type="button" name="reset"
onclick="return ValidateValue(); __doPostBack('ApplyBtn','')" />
The above is the code generated for asp server button button control on browser. Now my query is that irrespective of ValidateValue() returning true/false __doPostBack('ApplyBtn','') function is not showing any effect for me. My understanding is that string passed to onclick acts like function body, and return will from first function will return control preventing second function from execution.
Is that correct?
I have page on which I've a login control in which I've a subnit button. The problem is this that when I refresh the that page the submit button or any button that was clicked last before page refresh gets its click event automatically fired.
View 1 RepliesI am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive processing occurs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs.
How do i show a message in this case, that the processing is still going on and ask the user to wait.
I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page ?
