When you create a control, Microsoft Excel assigns it a set of default properties like those found in the built-in Microsoft Excel dialog boxes. The properties and their default values vary depending on the control. You can change these properties using the Object command on the Format menu.
To display or change a property of a control
1. Select the control.
2. On the Format menu, click Object.
3. Click a tab, and then review or change the property.
You can also click the control using the right mouse button and then click Format Object on the shortcut menu.
