Control.OnTextInputUpdate Method

Called before the TextInputUpdate event occurs.

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

Syntax

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

Parameters

Remarks

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

Notes to Inheritors

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