CoreTextEditContext.TextUpdating Event

Definition

Namespace:

Windows.UI.Text.Core

Occurs when the text input server needs to modify text inside the text input control. This event could be the result of a key event— such as inserting a single character— or the result of processing done by an input processor, such as auto-correction and prediction.

When handling the event, the text input control must replace a range with the new text provided by the server, and also move the caret to the end of the new text.
