code execution flow

[Jo]

Hi,

I have a small (hopefully!) problem. I have two buttons on my web page and when button A is clicked, the code behind takes about 3 seconds to execute. While it's executing though, I don't want the user to be able to click button B. What I have found happens is that if user clicks button B while button A is still executing, the code behind button B will start executing straight after the code under A has finished, and there is no page refresh/reload in between the two executions - that is my main problem.
I have searched the web to try to find a solution but have been unsuccessful. Can anyone tell me how I can either make button B disabled in the middle of button A's code execution (so once A is clicked, disable B, refresh the page and continue with execution of code under A), or end all code execution once the code under A has finished (ie do not go on to code under button B if it was pressed)?

Thanks for your help - greately appreciate it,

Jo

Re: code execution flow

Does A always get pressed before B? If so, then open the page with B
disabled or hidden, and enable/unhide it in A's code.

I wish it was that easy - B can (and in most cases will) be pressed before A. It could be pressed 10 times before A is pressed.

Re: code execution flow

Unfortunately, the code has to complete before the refreshed page is
returned to the user. Perhaps you could create additional controls so
that the application flows more smoothly? It's hard to visualize
without seeing it and understanding the process, but you probably need
to re-design the UI to take into account your workflow.

Re: code execution flow

So there's no way that in my code (at the end of a button click function) I can force the page to refresh without executing any further code (which is the next button click waiting to be executed)

Re: code execution flow

When you click the button, there's only 1 round trip to the server,
where the code is executed, and the refreshed page returned. What you
are asking would require two round trips, which is why I suggested
re-examining your workflow and UI to account for this.

Re: code execution flow

Thanks for your replies and your patience :-)
If you look at the Hotmail website (once you log in), they are doing exactly what I'd like to do. Ie when you press a button on that page, for example NewMessage, the page then begins to load, and you are unable to press any buttons on the page while it's loading - as if they were all disabled. This is what I need to achieve. Any idea how they might be doing that?

Re: code execution flow

Not being unfamiliar with Hotmail internals, I would guess that
they're running client-side script.
