Answer 1

Just a slightly more generic way of doing the same - should rule out potential errors where a css class might occur elsewhere in the CssClass property.

public void RemoveCssClass(WebControl controlInstance, String css)
{
    controlInstance.CssClass = String.Join(" ", controlInstance.CssClass.Split(' ').Where(x => x != css).ToArray());
}

Answer 2

NOTE: whether you add or replace a css class in codeBehind, remember to include equivalent attributes in both classes i.e. both having background-color, font-family...etc. because otherwise you may be fooled to think that the class never switched even though it did but didn't update the equivalent attributes.

Answer 3

lblName.Attributes.Add("class","urclassname"); //add class to lblName

Answer 4

You can replace "required" with an empty string:

lblName.CssClass = lblName.CssClass.Replace("required", "");

Answer 5

To remove css Class from Code Behind

lblName.Attributes["class"]=" ";

Answer 6

Use this:

object.CssClass= object.CssClass.Replace("MyClass", "");
