The drop-down calendar DataWindow option is available for use on any DataWindow column with an EditMask, and a Date, DateTime, or TimeStamp datatype. The DDCalendar EditMask property option allows for separate selections of the calendar month, year, and date. This option can be set in a check box on the Edit tab of the DataWindow painter Properties view when a column with the EditMask edit style is selected. It can also be set in code, as in this example for the birth_date column:
dw_1.Modify("birth_date.EditMask.DDCalendar='Yes'")
To make sure that dates selected with the drop-down calendar option are displayed with the desired edit mask for Web DataWindows, you should specify that the Client Formatting option be included with the static JavaScript generated and deployed for the DataWindow. To conserve bandwidth, JavaScript for client formatting is not included by default. To include this script, you can select the Client Formatting check box on the Web Generation page of the DataWindow Properties view or the ClientFormatting property in the Properties window in Visual Studio .NET. If you do not include script for client formatting, the drop-down calendar will use a default edit mask to display the column data based on the client machine's default localization settings.
