This above is the only code you wrote, correct? Out of curiosity, I tried
the same thing and had no difficulties, so I'll start you off by suggesting
the following (I'm sure others will have better ideas):

1. Is your TextBox1.Text = ... really broken inside the literal string with
a newline?. If it is, fix that and try again. If that doesn't work...

2. Be sure you didn't modify any generated code. To be sure, create a new
project just like this one and see if the error is reproduced.

3. If the error repeats, try to repair your installation of VS.NET

HTH!

This kind of error occurs when you have used incorrect
syntax in your aspx file (not the codebehind). It occurs
when the aspx page cannot be compiled.

If you want further help here, send in the aspx source so
we can see where the error is, or if you want to do it
yourself, click on the "show full source" (or something
like this) link on the error page, and go to the specified
line to see what it is trying to do.
