Description

The DateTimePickerEx component implements a drop-down calendar, which enables the user to edit date and time values with additional settings to change calendar appearance. The calendar supports dates within the range between 01.01.1601 and 31.12.9999.

Working with the Component

Different Show* properties enable the user to set up component appearance. These properties enable the user to determine the following settings:

• Whether to display the checkbox, managing access to editor (ShowCheckbox).

• Whether to display fields for editing time component (ShowTime).

• Whether to display buttons responsible for the mode of setting date in the calendar (different ShowMode* properties).

Data setting mode can also be set using the Mode property. Data can be set by selecting one of the periods corresponding to the mode. Value of the CurrentDate property will correspond to beginning of the selected period.

The MinDate and MaxDate properties can be used to limit a range of dates, in which the user can select value.

Features of Use
