Assembly: System.Windows (in System.Windows.dll)

Exceptions
| Exception | Condition |
|---|---|
| NotSupportedException | The NavigateUri property is not or cannot be converted to an absolute URI. |
| InvalidOperationException | The TargetName property is set to a value that contains embedded whitespace. |
Remarks
This method will try to convert the NavigateUri to an absolute URI if necessary. If the conversion cannot be completed or the specified URI cannot be found, an exception will be thrown.
Raising an event invokes the event handler through a delegate. The OnClick method is called before any event handler for the Click event. This method allows derived classes to handle the Click event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnClick in a derived class, be sure to call the base class’s OnClick method so that registered delegates receive the event.
