Actually Sarangrao.....I didn't understand, what did you mentioned by commenting session values and then uncommenting Qureystring..and then viewing old values no new values....
What are you just trying to say...don't panic stay cool and ask your question in a better way....
The second thing about debugging is.....
Eitheir you must have not build and Run the project and just right clicked on the open page in VS.net and clicked on View in Browser....
So it wouldn't actually go in debug mode be it any number of breakpoints
And if you're building it and still it doesn't enter in debug mode then
There's this second issue....VS 2005 IDE has this problem of detaching from the debugger after the page is successfully loaded as you see in run mode the pause and stop buttons might nbot be visible...
So to resolve this.... close VS IDE and open the IDE again and reload the project and then try debugging...if this does'nt work then try rebooting your computer....
always remember when you're running your web App on Interner Explorer.
There's always an issue of Page Caching.....means it will use old resources stored in "Temporary Internet Files" Folder and it happens often..
with images ,flash content etc.....
and with controls too....
So when you're running the page and updating simultaneously on the IDE always use this dummy qury string at the end
