Control.OnTextInput Method

Called before the TextInput event occurs.

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

Syntax

'Declaration
Protected Overridable Sub OnTextInput ( _
    e As TextCompositionEventArgs _
)
protected virtual void OnTextInput(
    TextCompositionEventArgs e
)

Parameters

Remarks

The OnTextInput method is called before any event handler for the TextInput event is called. This method allows derived classes to handle the TextInput 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 TextInput event data.

Notes to Inheritors

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