Properties

Name	Description
AcceptsExpression	Gets or sets a value that indicates whether the control accepts and evaluates a basic formulaic expression entered as input.
AllowNull	Gets a value indicating whether a null value is allowed as input. Set to false if you're binding to a non-nullable value
Description	Gets or sets content that is shown below the control. The content should provide guidance about the input expected by the control.
Header	Gets or sets the content for the control's header.
HeaderTemplate	Gets or sets the DataTemplate used to display the content of the control's header.
InputScope	Gets or sets the InputScope for the NumberBox.
IsWrapEnabled	Gets or sets a value that indicates whether line breaking occurs when header text extends beyond the available width of the control.
LargeChange	Gets or sets a number that is added to or subtracted from Value when a large change is made, such as with the PageUp and PageDown keys.
Maximum	Gets or sets the numerical maximum for Value.
Minimum	Gets or sets the numerical minimum for Value.
NumberFormatter	Gets or sets the object used to specify the formatting of Value.
PlaceholderText	Gets or sets the text that is displayed in the data entry field of the control until the value is changed by a user action or some other operation.
PreventKeyboardDisplayOnProgrammaticFocus	Gets or sets a value that indicates whether the on-screen keyboard is shown when the control receives focus programmatically.
SelectionFlyout	Gets or sets the flyout that is shown when text is selected, or `null` if no flyout is shown.
SelectionHighlightColor	Gets or sets the brush used to highlight the selected text.
SmallChange	Gets or sets a number that is added to or subtracted from Value when a small change is made, such as with an arrow key or scrolling.
SpinButtonPlacementMode	Gets or sets a value that indicates the placement of buttons used to increment or decrement the Value property.
Text	Gets or sets the string type representation of the Value property.
TextAlignment	Gets or sets the text alignment of the text in the control.
TextReadingOrder	Gets or sets a value that indicates how the reading order is determined for the NumberBox.
ValidationMode	Gets or sets a value that specifies the input validation behavior to invoke when invalid input is entered.
Value	Gets or sets the numeric value of a NumberBox.

Methods

Name	Description
OnApplyTemplate()	Invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class.
OnCreateAutomationPeer()	When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure.

Events

Name	Description
ValueChanged	Occurs after the user triggers evaluation of new input by pressing the Enter key, clicking a spin button, or by changing focus.
