In Visual Studio, you can expand and collapse code without using regions, for example in a code-behind page you can collapse methods, etc... And in an ASPX page you can collapse tags, tags, etc...
It's useful when you have a long page and you want to focus your development on a specific part. What's cool about it too is that you can close the file and reopen it and the state of the expanded/collapsed blocks is saved exactly as you left it.
Except in one instance. That state is not saved for tags in ASPX pages, where it would be most useful.
I know there are some good plugins out there for VS but I couldn't find one that addresses this issue.
Has anybody got a solution?
Before you mention custom controls, they are not always convenient or feasible when trying to keep a page short and I don't consider this a solution to this problem.
Looks like this issue will stay unresolved at this time.
I opened a bug report on Microsoft Connect, if this issue is important to you please vote it up!
