Chapter 7: Databases and Data Sources

Customizing controls

With some controls, one can simply drop them on a form and use them as is. That works for

things like a Text Box, Date Field, or Time Field. With others, though, once the control is

added, one may need to provide additional information. Even for those that work

immediately, a user may customize their appearance or behavior.

To set up a control, click it to select it (sizing handles appear around the edges), and then

choose Control from the shortcut menu, Format > Control from the menu, or Control

from the Form Controls toolbar. The Properties dialog for the control appears. The

contents of the Properties dialog vary, depending on the type of control.

Just as the contents of the Properties dialog vary with the type of control, so does what one

needs to do to get it working. Table 2 lists some of the items common to a number of

controls.

Table 2. The Properties dialogs for the various controls lets one set them up as wanted. The properties shown

here are common to a number of the controls.

Property Meaning

Name Identifies the control. In some cases, including option buttons, assigning the

same name to several controls turns them into a group.

Label The caption that appears on the control.

Label field Links the control to a Label Field control. Used for controls (like Text Boxes)

that don't have their own label.

Enabled Determines whether the control is available to the user.

Tabstop Determines whether the control is part of the tab order, that is, whether the user

can reach it by tabbing from one control to the next.

Order Determines the position of the control in the tab order.

Character set Specifies the font characteristics for the control.

Default value Specifies the initial value displayed in the control.

Background

color

Specifies the background color for the control.

Help text Specifies the tooltip for the control.

Individual controls have additional properties related to their purpose. For example, a Check

Box has a Default Status property that determines whether it's initially checked and a Text

Box has a MultiLine input property that determines whether one can put multiple lines of text

into the control.

Some controls need certain properties specified in order to be useful. In some cases, wizards

are available to help the user specify the necessary information. The next few sections

consider some of those controls.
