I have couple of newly created pages.The back button of the browser works fine normally and redirects me to previous page correctly, But when i click on back button after any events in the page (ex:Dropdown Index changed..) i am getting page cannot be displayed error. What might be the problem??
I have checked for answers and came across Cache concept but i dont know how to include it in these two pages.....
Because ASP.Net uses POST requests to process events that must be handled by the server-side and browsers will not automatically re-issue POST requests, you'll get this message.
The message should identify that you can click "Refresh" or "Reload" to recreate the POST request and load the page.
so is there any way to solve it other than "Reload" and "Refresh".
Use the querystring, AJAX, an embedded application, ... it's completely up to you and your development preference.
