ASP.NET menu seems to clear browser's history [modified]
-
Hello everyone. I have a reporting application, in which you can choose some different kinds of report through a simple ASP.NET menu webcontrol, fed by the regular web.sitemap file. Each report page has several pages of detail, which you access by clicking on one item of those listed in the page. Some of the detail pages are shared between two or more report pages, and the parameters are passed through querystring. Nothing new or weird so far. The big problem started when we were asked to provide a "back" button for each page. This button is based on browser history and should get you back to previous page no matter where you are. Our big issue is that sometimes, accessing a report from the menu seems to clear the browser's history, thus rendering our smart "back" button useless. Is there some undocumented bug in the ASP.NET menu control, which may cause this issue? Any help would be much appreciated. Thanks in advance, Rey9999 UPDATE: the application runs fine in IIS 5.1, the issue seems to be in IIS 6. Also, not only navigating through the menus, but also filtering the report data sometimes clears the history. Any ideas? what is changed between iis 5 and 6 about how history's managed? FURTHER UPDATE: My fault; it is not the web server, but the database which causes the issue. When i use a small test database, everything works. When i use a large production database, the problem shows up. It's almost like the browser "resets" itself when the page takes too long to fetch the data from the DB. BTW, I'm using SQLExpress 2005. Can anybody help? This time I'm really stuck and even googling can't help me. Please give me an hand. :( YET ANOTHER UPDATE: It seems to happen with IE (6 & 7) only. Gecko-based browsers run just fine. Really, can't get head nor tail out of this. Rey9999
