Hello,

In my module, I have button A. When I click button A, it's suppose to refresh the page, adding query string into the URL so that the Page load can read the query string and do the right job.

This works OK. However, if I leave the webpage on overnight and click button A again the next morning, the page just refresh. It doesn't seem like the button click even registered.

Q1) Am I suppose to refresh the controls in order to avoid this situation? Why? How?

Q2) I have to do the page redirection because I don't want the user to not be able to click the back button. It seems like all ASP buttons use POST and so redirecting it simulates a GET request rather than a post request. Is there a cleaner way of doing this?

Please help me, this has been a big problem for me. Thank you.

I'm sorry. Let me be more clear:

I have a gridview with button A, B.

There's a home button (H) (Not part of the gridview)

Buttons A, B, H works as expected. At 5:00 PM, I click button A. The query string is &A=1.

Overnight, when I click button B, the query string is still &A=1. I expect it to change to &B=1.

Overnight, clicking the Home button doesn't take me home either: query string is still &A=1. I expect clicking the home button to remove all of the query string I've added (no &A=1 or &B=1). 

I hope I've answered your question.

Another thing I want to ask is if this is related to ASP.NET page unloading? If there is a possibility, can you explain the correlation? I'm thinking it might be related because since the website is not being accessed overnight, it seem like it might be unloaded, but then why does that not trigger a button click event? Another reason is when the page refreshes, sometimes, it take a while to refresh, and this behavior is similar to the behavior I've read about when a page unload. If this is a possibility, how can I force this situation to happen? What other possible explanations are there?

Thank you for your reply. I don't think the JS method will work with my situation, and these are query string values that I am working with. However, since you also think that it's the page unloading issue, I have a few options that I can try out, maybe the DNN keep alive modules will do. I'll look into these when I have time. Thanks again.
