.designer files cannot be generated
An issue that is very common designing web forms in ASPX when the .designer file is not generated. I have wondered so many times on the reasons why I cannot access some of my controls in code-behind, when changes has been made in the ASPX page. I just discovered that it says so in the Warning pane. The warning pane is something I rarely use during development of my ASPX pages, so it is excellent to know where I finally can find the answer to all my .designer problems. Simple really, but may be not so intuitive?!
