Restricting the years displayed
To make it easier for users to select valid dates, you can restrict the number of years that are displayed relative to, and including, the current date. At run time, only values that fall within the range of dates that you specify are visible on the calendar widget or available by using spinners or drop-down fields.
Click the control, and then click the View properties icon.
For the Display Range option on the Presentation tab of the Properties panel, specify a number of years in the Previous __ years field, the Next __ years field, or both.
By default, both fields are set to 10 years.
When the Display mode field is set to Text Input + calendar and an application user enters a date that is outside the range of years that you specify with the Display Range option, the range of years is updated automatically to include a range of years starting from the entered year or ending at the entered year.
- Date time (calendar) control
To present a date, time, or both on a form, use the Date time control. You can modify the control features to improve user experience by making date and time selection simple and intuitive. For example, you can choose to display the calendar widget with spinners to make it easier to switch between months and years.
- Configuring the basic settings for a Date time control - a date or time
Select a property for a Date time control to determine the dates and times that the application users can select. Set related options to specify the label, default value, helper text, and field visibility for the control.
- Specifying presentation options for a Date time control
You can specify how read-only dates or date and time combinations are displayed in your application. For example, you might specify that the year comes first, or that months are spelled out rather than represented numerically.
- Selecting the date and time format and display mode
You can specify which date and time element selectors are displayed on the form at run time. For example, you can display a calendar widget with a corresponding text input field or display drop-down fields for selecting the month, day, and year.
- Selecting spinners or drop-down fields for navigation
You can specify whether your application users select dates and times with spinner controls or drop-down fields.
- Displaying week numbers in calendar widgets
If users are accustomed to seeing week numbers in calendars, you can specify that the week numbers are displayed along the left side of the calendar widget in your application. The week numbers are shown according to the ISO 8601 standard date notation. Week numbers may vary, depending on locale.
- Disabling the selection of weekend days
To make it easier for users to select valid dates, you can disable weekend dates so that users cannot select them in your application. Weekend (non-working) dates can be based on the user's calendar or on another business calendar.
- Setting intervals of minutes
By default, the time picker displays minutes from 0 through 59. To restrict the time selections available to users, you can configure your application to display intervals of minutes on time controls, instead.
- Specifying read-only and edit options for a Date time control
Edit options determine when a control is editable or read-only for the application's users.
- Specify actions for a control
You can specify action sets—event-action pairings—to determine the behavior of a control. For example, you might specify that clicking a button triggers the refresh of a section. You can define multiple events and actions in an action set, and you can create multiple action sets for a single control.
- Copying, moving, or deleting a control
You can use basic Windows operations to speed the development of your controls.
