By default, the AllowHotState property is false. Use the Style property to specify the control's style. The Style property changes the AllowHotState and UseFocusSkin properties based on the style used. Use the Skin property to assign custom skins for specified states. If the AllowHotState property is True, the Skin(exHot) gets displayed when the cursor is over the button.

Please be aware that Style property changes the following properties, based on the style chosen: 

• AllowHotState property
• UseFocusSkin property
• Skin
• FocusSkin

If you require certain value for the AllowHotState property you have to change the AllowHotState property after changing the Style property.

For instance, the exDefault predefined style for hot state ( when the cursor is over the button ).
