Hello All,
is there a simple way of preventing page refresh in .net

I had to write some code to assign a session variable to prevent refereshing the page.

Any simpler methods ?

thanks

How do you stop keybord shortcut Ctrl-F5?

What I meant, is that you cannot stop the refresh of a page.
An user can press F5 or Ctrl-F5 to refresg the page anyway.
Or click the Refresh button.

Or maybe you are referring to another underlying problem and think refresh of page is the problem?

no no no

Well with webforms, when u have a page that might take a while to process. You dont want users refreshing the page in an auto postback. I wrote a script to stop it. But having loads of ajax controls, which also make postbacks to the page when called. It conflicts with the script and loops endlessly.

So its flawed. so am looking for a simpler way around it.

I got a way around it.

I wrote a custom function on the button event. But any other options are welcome.

For an ordinary refresh, yes.
If you also want to reload the cache, use Ctrl-F5.

I found a very simple way.

Set a hidden value in the form, and increment it on the button1 click event. So if it is a postback the value is 1 and if its onpage load the value is 0

And for the button load event, it will redirect it to a fresh page if its a referesh.

Quite simple :)



        string SendOnce = count.Value.ToString();
        if (SendOnce == "1")
        {
           goto endexecution;
        }
        if (SendOnce == "0")
        {
            count.Value = "1";
        }
