Move Focus
This feature supports keyboard navigation between Input controls. The following properties control how focus moves to or from the control.

ExitOnLeftRightKey: moves focus from the Input control when the Left or Right arrow keys are pressed. The default value is None.
TabStop: determines whether the TAB key moves focus to the Input control from the previous control. The default value is True.
The following table lists the values and behavior of these properties.
Property | Possible Value | Description |
|---|---|---|
ExitOnLastChar | True | Moves focus from the Input control when the entered text reaches the MaxLength value or when the input mask is filled. |
False | Keeps focus in the Input control even when the entered text reaches MaxLength or the mask is filled. | |
ExitOnLeftRightKey | None | Arrow keys do not move focus from the Input control. |
Left | Moves focus to the control on the left when the Left Arrow key is pressed. | |
Right | Moves focus to the control on the right when the Right Arrow key is pressed. | |
Both | Moves focus to the adjacent control on the left or right depending on the arrow key pressed. | |
