Guidelines for Creating a Text Control or List Column
If you create a text control or text list column, then use the following guidelines:
To display a calendar or calculator for a control, set the Runtime property of the control to TRUE.
To display a pop-up editor, set the Popup Edit property of the control to TRUE.
To make a list column unavailable, set the Available property to FALSE.
To display a text list column in a list by default, set the Show in List property to TRUE.
To hide a text list column by default, set the Show in List property to FALSE. The user can use the Columns Displayed dialog box to display the text control.
A list column header is a specialized control, so it does not render HTML. For example, you cannot add an asterisk to indicate that a field is required, as you can in a form applet. For more information, see Caution About Using Specialized Classes.
You cannot apply a background color to a list column.
