You can try to use the built-in "ASP vb.NET" syntax definition.

You can also add custom syntax definitions to Textastic by using TextMate bundles. See

This is not really the right forum since it is for the Mac version of Textastic, but anyway: Currently, the iOS document picker only supports opening a single file/document, not a folder. However, I'm working with the author of Working Copy to find workaround.

For local preview, Textastic basically loads the file similar to the file:// protocol in a desktop browser. Browsers do not store cookies for local files. I'll consider using a full HTTP server for local preview in a future version of Textastic.

Yes, the Firebug integration could be better. I'll try to improve this in future updates.

Textastic uses the standard key mappings of the OS X text input system. While you can define your own menu shortcuts in System Preferences, AFAIK this is not possible for text input keys.

I'm not sure what you mean when you say "crushing"?

Regarding line endings: does your file possibly have mixed line endings? Textastic scans the file until it finds the first line ending and uses this when it saves the file. So, for example, if your first line ends with LF and the following lines end with CRLF, the file will be converted to LF line endings when it is saved.

Can you send me the original unmodified file so I can have a look at it? You can send it to support@textasticapp.com

I haven't heard of such a problem before. Does your server maybe limit the supported authentication methods?

Please try to enable the "Debug Log" setting in the connection's settings screen. Tap on the (i) button on the right side of a connection to change its settings. This creates a log file when you try to connect to the server which might help you find out what's wrong.

Textastic for Mac does not currently have regular expression search and replace. Only the iOS version supports it at the moment.
