Question

I have two user controls that need to add a class atribute to the body tag of my page, however they currently over write one another if I just use

Body.Attributes.Add("class","value")

So I need to check if the class attribute exsists and if it already contains the value Im going to add.

If Not Body.Attributes("class").Contains("value") Then
  Body.Attributes.add("class", Body.Attributes("class") + " " + "value")
End If

Thanks for you time, any help gratefully received.

EDIT:

The contain constraint doesnt return the expected value, resulting the the class not been concatinated,
Example:
add class “dog” then I a different instance of the same control tries to add “dog” but the contains(“dog”) returns false

Answer 1

After a little more coding I tried using Indexof() the value I was searching for. This allowed me to know if the class attribute contained the value already.
