In This Topic

This feature makes navigating through the controls easier and allows you to add keyboard navigation support to the C1Input (C1TextBox, C1ComboBox, C1DateEdit, C1DropDownControl and C1NumericEdit) controls. The following properties enable you to move focus from or to the C1Input controls.

ExitOnLastChar: Moves focus from the C1Input control either when the length of the text entered reaches the maximum length, as defined in the MaxLength property, or when the mask is filled. Its default value is False.
ExitOnLeftRightKey: Moves focus from the C1Input control when the left or right arrow keys are pressed. Its default value is None.
TabStop: Indicates whether the focus is moved to the C1Input control, from the control on the left, when the TAB key is pressed. Its default value is True.
