ASP.NET and Active Schema

[Guest]

All,

I have a ASP.NET page that has been converted from a .htm page which has a
LINK and style tag underlined in red. When I hold the mouse pointer over
them I get the following message: "The active schema does not support the
element 'style'" but when I run the page I get no errors and it displays
fine. What is going on here and is this an error?

Thanks
Msuk

When the WebForm renders.

You can see this if you find the .vb file the ASP.NET runtime
generates from the ASPX page. It will be in the Temporary ASP.NET
Files directory where the framework is installed and the relavant part
would look something like:

Public Class temp_aspx
...

Sub Output()
Response.Write("Foo")
End Sub

...


Private Sub __Render__control1( _
ByVal __output As HtmlTextWriter, _
ByVal parameterContainer As Control)

parameterContainer.Controls(0).RenderControl(__output)

Output()

End Sub

...

End Class

Oh, I apologize msuk, I don't how that post ended up here!

In regards to your problem, I think it is a message you can safely
ignore. The IDE tries to be helpful and smart but it isn't flexible
enough to handle all the valid syntax and constructs that can go into
HTML / ASPX. It has a list of things that are valid, but it is only a
subset of all the things that are really valid. Know what I mean?

Hi,

thanks for your response, is their anyway to switch this off or load the
correct HTML/ASPX schema's?

Thanks

I believe you can turn it off under Tools -> Options -> Text Editor ->
Html/XML -> Html Specific -> Enable HTML Validation. Whew, what a
mouthful.

You can modify these schemas. I've never tried but I believe there are
some articles floating around on the subject. I can see the .xsd files
it uses for validation in
<vs.net install dir>\Common7\Packages\schemas\html
