To edit a control’s properties, click on the control in your form. The Forms Designer’s Properties area will display the control’s existing properties, so you can edit them.
Controls have Setting Properties and Style Properties. Generally speaking, Setting properties affects the control’s behavior and Style properties affect its appearance.
The specific properties you see depend on the type of control you've selected in your form; some controls have more properties than others.
All properties are optional, with the exception of the control label.
