CssStyleCollection::Add Method (String, String)

Adds a style item to the CssStyleCollection of a control using the specified name/value pair.

Namespace:  System.Web.UI
Assembly:  System.Web (in System.Web.dll)

public:
void Add(
	String^ key, 
	String^ value
)

Parameters

key
Type: System::String
The name of the new style attribute to add to the collection.
value
Type: System::String
The value of the style attribute to add to the collection.

ExceptionCondition
ArgumentNullException

key is nullptr.

If the style item to add exists in the HtmlTextWriterStyle enumeration, use the overload of the Add method that takes an HtmlTextWriterStyle parameter because it is strongly typed. This means that items that are added will be included when viewing items with the get accessor of the Item property.

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.

No code example is currently available or this language may not be supported.
