MORE INFORMATION

Steps to Reproduce Behavior

  1. Create a form and place the following code in the Click event:
    WAIT WINDOW "Form Click"
  2. Add a container control to the form with the following in the control's Click event:
    WAIT WINDOW "Container Click"
  3. Add a command button to the container with the following in the button's Click event:
    WAIT WINDOW "Command button Click"
  4. Set the Enabled property of the command button to .F.
  5. Run the form and click the command button inside the container.
To see this behavior with a pageframe, follow these steps:
  1. Create a form and place the following in the Click event:
    WAIT WINDOW "Form Click"
  2. Add a pageframe control to the form. Select the control and place the following in the page1 Click event:
    WAIT WINDOW "Page1 Click"
  3. Add a command button to page1 with the following in the button's Click event:
    WAIT WINDOW "Command button Click"
  4. Set the Enabled property of the command button to .F.
  5. Run the form and click the command button on page one of the pageframe.

    Note that the form's Click event fires instead of the Click event of the container object when the disabled button is clicked. Similar behavior occurs with the pageframe. Instead of activating the page or pageframe's Click event, the form's Click event is called when the disabled button is clicked.

    The behavior is different in Visual FoxPro 3.0b and 5.0x. In these versions, the Click event of the container occurs when clicking the disabled button inside of it. In the case of a pageframe, the Click event of the page fires.
