Control.OnTextInputUpdate Method
Microsoft Silverlight will reach end of support after October 2021. Learn more.
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
- e
Type: System.Windows.Input.TextCompositionEventArgs
A TextCompositionEventArgs that contains the event data
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.
