CssStyleCollection.Add Method (HtmlTextWriterStyle, String)

Adds a style item to the CssStyleCollection collection of a control using the specified HtmlTextWriterStyle enumeration value and corresponding value.
Assembly: System.Web (in System.Web.dll)
Parameters

Type:
System.Web.UI.HtmlTextWriterStyle
The HtmlTextWriterStyle enumeration value to add to the collection.
- value
-
Type:
System.String
The value of the style attribute to add to the collection.
If the style item to add exists in the HtmlTextWriterStyle enumeration, use this Add overload of the Add method rather than the overload that does not take an HtmlTextWriterStyle parameter.
The following code example demonstrates how to use both overloads of the Add method to add a cascading style sheet to an HtmlSelect, HtmlInputSubmit, and a Label control programmatically.
