Difference between Class vs CSSClass in ASP.Net CSS + CSS syntax question

Answer 1

Actually, there is a difference between class and CssClass: the class will not be seen by the code behind, but the CssClass will.

Thus, if you add a new class to a control in your code behind, for example:

myControl.CssClass += " foo";

while your control is set as follows:

(Note class attribute: class="Text")

When inspecting your rendered element in your browser, you will see that it will be rendered as follows:

(Note how the class has been overridden: class= " foo".)

If you set the CssClass on the other hand:

you will get it rendered (as expected) like so:

(note the class has now both classes set, as expected! class="Text foo")
