ProvidePropertyAttribute Class

When you mark a class with this attribute, you tell the code generator to create an extender property with the name you provide. The marked class must implement IExtenderProvider. As a result, the new property can be used by other components in a container.

Within the marked class, you must implement Get <name> and Set <name> methods. For example, if you mark a class with [ProvideProperty("PropertyName")], you must implement GetPropertyName and SetPropertyName methods. To specify that the new property will be an extender property, you must implement from IExtenderProvider, you must also implement a CanExtend method.

For more information, see Attributes Overview and Extending Metadata Using Attributes.

The following example marks MyClass with a ProvidePropertyAttribute that tells the compiler to create a property called MyProperty from the GetMyProperty and SetMyProperty methods.

[ProvideProperty("MyProperty", typeof(Control))]
public class MyClass : IExtenderProvider {
    protected CultureInfo ciMine = null;
    // Provides the Get portion of MyProperty.  
    public CultureInfo GetMyProperty(Control myControl) {
        // Insert code here. 
        return ciMine;
    }

    // Provides the Set portion of MyProperty. 
    public void SetMyProperty(Control myControl, string value) {
        // Insert code here.
    }

    /* When you inherit from IExtenderProvider, you must implement the 
     * CanExtend method. */ 
    public bool CanExtend(Object target) {
        return(target is Control);
    }

    // Insert additional code here.
 }
