Public Class GcTextBox
    Inherits EditBase
    Implements IAnimatable, IFrameworkInputElement, IInputElement, IQueryAmbient, IAddChild, ISupportInitialize

Remarks

The GcTextBox is a composite control that that is composed of several encapsulated components. Consequently, some events do not bubble up to the containing control because they are handled by encapsulated child elements. Because of this, application developers should listen for the tunneling version of an event (denoted by the prefix "Preview").

GcTextBox supports unformatted and formatted text.

Horizontally and vertically aligning text within a GcTextBox is done with the HorizontalContentAlignment and VerticalContentAlignment properties. Aligning the GcTextBox within the layout of the page is done with the HorizontalAlignment and VerticalAlignment properties.

The best way to hide the border around a GcTextBox is to set the BorderThickness property of the GcTextBox to 0.

Scrollbars are not visible on a GcTextBox by default. To make scrollbars visible, set the VerticalScrollBarVisibility and HorizontalScrollBarVisibility properties to Visible or Auto.

Usually the TextChanged event should be used to detect whenever the text in a GcTextBox changes rather then KeyDown as you might expect.
