Control.OnTextInputStart Method

Silverlight

Called before the TextInputStart event occurs.

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

protected virtual void OnTextInputStart(
	TextCompositionEventArgs e
)

Parameters

e
Type: System.Windows.Input.TextCompositionEventArgs
A TextCompositionEventArgs that contains the event data.

The OnTextInputStart method is called before any event handler for the TextInput event is called. This method allows derived classes to handle the TextInputStart event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

This implementation does not change the handled state (the Handled property) of the TextInputStart event data.

Notes to Inheritors

When overriding OnTextInputStart in a derived class, be sure to call the base class’s OnTextInputStart method so that registered delegates receive the event.
