Getting to know the Web Controls

Lesson 15 - WebDateForm

In this lesson we will look at the WebDateForm control in DataFlex. The WebDateForm is a data entry object for date values. Entering date values is something that is often used in web applications. Consider, for example, booking a holiday where you can enter a departure and arrival date. A monthly calendar will pop up, after clicking the prompt button. Let’s take look at it in the next example.


  • This example demonstrates a simple page of a web application for booking a vacation.
  • We can fill in all the information and especially the first and the last day of the vacation. 
  • If I click the little calendar prompt on the right. The calendar will pop-up. Now I can select a date. I can change the month or even the year to select a date. It is also possible to click on the today’s date.
  • This WebDateForm can be used with or without a data binding.
  • There are some interesting properties to check:
    • The ShowToday and ShowWeekNr properties are set to true by default. 
    • It shows the weeknumber on the left side of the calendar and the today’s date at the bottom. 
    • You can click on this to select today’s date. 
    • AutoShow is false by default. If you set this to true. 
    • The calendar automatically pop-up when the form gets the focus.
  • As you can see the WebDateForm is easy to use.
