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

try

txtBox.Attributes.Add("class", "my_Class1 my_Class2");

Answer 2

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");

Answer 3

You can also try

txtBox.CssClass = "myClass1 myClass2";

Answer 4

try

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

I think this will work.
