I have a website in ASP.NET with C#
when I compile the project I have no errors.
When I do have an error I see besides the  new error many error in the HTML code. (validation erros)
Why I don't see these errors all the time.
I gauess this is a parameter in the debugging mode but I don't know where.
for example:

Validation (XHTML 1.0 Transitional): Element 'td' is missing its closing tag.      
Validation (XHTML 1.0 Transitional): Element 'img' is missing required attribute 'alt'.      
Thankyou
Anat

See this

http://www.w3schools.com/tags/tag_doctype.asp
http://htmlhelp.com/tools/validator/doctype.html

It's about the
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > - line in the .aspx file

The question is how to cause the compiler to show these error messages in each compilation and not only when there are other errors.

Hi, HTML validation errors are shown as warnings, to see them you have to open the Error List Window after you compile your program, it may also be the case that you have to enable the warnings to be visible in this window as well.

Hi,
VS validates you'r HTML based on the
DOCUMENTTYPE declared in the aspx file
try changing the
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

To

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

Is it enable in visual studio options?
Check the Show Errors option in Tools->Options->Text Editor->Html->Validation
