In my web application, I have a search form. I add information in the boxes provided / select values from ddls and then click the Search button. The search results are loaded on the same page. Now I change the search criteria and click the Search button again. This reloads the same page with new set of results. Now if I click browser back button, I get "Webpage has expired" message. The complete message is as following:
Webpage has expired Most likely cause:
The local copy of this webpage is out of date, and the website requires that you download it again. What you can try: Click on the Refresh button on the toolbar to reload the page. After refreshing, you might need to navigate to the specific webpage again, or re-enter information.
If I click browser back again then page loads resetting the search criteria. Is there any way to avoid this "Webpage expired" message? I am okay even if the page reloads by resetting the search criteria.
I've got popup (using javascript) working in a kind of gridview. When you click a button on one grid, it displays a popup window containing another grid of information, based on the row clicked in the first grid.
This works well... I've enabled editing in the grid that is popped up. When you click edit though, the popup window disappears. If I click the display button in the first grid though to bring the popup window visible again it displays, and is now in edit mode.
Is there a way to make postbacks in the popup not close the popup?
