How to add two CSS Class to control in the code behind?

Question

I am setting 2 css class in the code behind in ASP.NET

I could either do:

txtBox.Attributes.Add(\"class\", \"myClass1\");
txtBox.Attributes.Add(\"class\"         


        

Answer 1

The Add method is actually a Put, since it replaces the value behing the key "class". In HTML/css you can have several classes by separating with a space.

txtBox.Attributes.Add("class", "myClass1 myClass2");
