Hi,
Could you please help to check whether this issue is related to Visual Studio? Please restart PC, run VS as admin, create a new and simple ASP.NET web app, drag and drop a standard control on a page to check the result.
If the issue only occurs with the specific project, you can copy all the files of the problematic project into new web app.
If the issue occurs at all web projects, do you run an ESET NOD32 antivirus? There's a known compatibility issue between this antivirus software and Visual Studio. See the issue details at:

To resolve the problem, we need to uninstall ESET NOD32, or at least rollback the antivirus to an old version.
If you don’t use ESET NOD32, please disable anti-virus software on your machine or some extensions related to Visual Studio.
Also you can try some devenv commands to fix:
1.devenv.exe /safemode
2.devenv.exe /resetskippkgs
3.devenv.exe /installvstemplates
4.devenv.exe /resetsettings
5.devenv.exe /resetuserdata
devenv.exe can be located under your VS location/Common7/IDE
If no help, please uninstall and reinstall Visual Studio 2013. During reinstalling VS2013, please check whether there are any errors, if there are, please consult
on Visual Studio Setup and Installation forum:
