Provides handling for the Click event.

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

Syntax

'Declaration
Protected Overrides Sub OnClick
protected override void OnClick()

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.
