Examples. The following example includes an implementation of this callback to validate a range of values for a custom dependency property. In this case the property value expects an enumeration, and the validation assures that the provided value evaluates to a member of that enumeration. C#.

The function to which the callback is passed is often referred to as a higher-order function. For example, to find the number of methods in a delegate's invocation list, you may write: int invocationCount = d1.GetInvocationList().GetLength(0); Delegates with more than one method in their invocation list derive from MulticastDelegate, which is a subclass of System.Delegate. When implementing dependency properties, you typically use the CoerceValueCallback and PropertyChangedCallbacks to enforce relationships between properties. For example, assume we have a Person class with BirthYear, DeathYear and MarriageYear properties.

The examples above are not very exciting. They are simplified to teach you the callback syntax. Where callbacks really shine are in asynchronous functions, where one function has to wait for another function (like waiting for a file to load).

The following examples show how to use android.webkit.WebChromeClient#FileChooserParams .These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. In this article, I’ll demonstrate with a few simple examples why we need these hooks and when and how to use them.
