Property Value

Type: System.String
Default = Id of the containing class.

	[Association(Name="FK_CustomerCustomerDemo", Storage="_CustomerDemographic", ThisKey="CustomerTypeID", IsForeignKey=true)]
	public CustomerDemographic CustomerDemographic
	{
		get
		{
			return this._CustomerDemographic.Entity;
		}
		set
		{
			CustomerDemographic previousValue = this._CustomerDemographic.Entity;
			if (((previousValue != value) 
						|| (this._CustomerDemographic.HasLoadedOrAssignedValue == false)))
			{
				this.SendPropertyChanging();
