Enabled Property (DayOfMonth)

Determines the enabled state of this object.
Syntax
'Declaration
 
Public Property Enabled As Boolean
public bool Enabled {get; set;}
Remarks
You can use the Enabled property to selectively activate or deactivate an object. When an object is disabled, its appearance changes (based on the system disabled colors) and it becomes unavailable to the user. Certain properties or methods of the object may also be unavailable through code when it is disabled.
Example
This example uses the DaysOfMonth collection property to disable the first day of all months in all years.

        '	Get a DayOfMonth object for the first day of the month
        '	Note that the DaysOfMonth collection is one-based so as
        '	to be more intuitive to use

            dayOfMonth.Enabled = False
        End If
