More NuGet

I have just put up the the first instalment of my Dynamic Data Extensions this version (V1.0) we have

• HideColumnIn attribute see A New Way To Do Column Generation in Dynamic Data 4
• ShowColumnOnlyIn attribute does what it says on the tin shows column in particular page templates
• Filter attribute (I have only implemented the Order property as yet) this allows you to set the filter order.

Example Metadata

[MetadataTypeAttribute(typeof(Order.OrderMetadata))]
public partial class Order
{
    internal sealed class OrderMetadata
    {
        public string CustomerID { get; set; }
        public Nullable<int> EmployeeID { get; set; }
        public Nullable<int> ShipVia { get; set; }

        [ShowColumnOnlyIn(PageTemplate.List)]
        [ScaffoldColumn(true)]
        public int OrderID { get; set; }

        public Nullable<DateTime> OrderDate { get; set; }

        [HideColumnIn(PageTemplate.List | PageTemplate.Insert)]
        public Nullable<DateTime> RequiredDate { get; set; }

        [HideColumnIn(PageTemplate.List | PageTemplate.Insert)]
        public Nullable<DateTime> ShippedDate { get; set; }
        public Nullable<decimal> Freight { get; set; }
        public string ShipName { get; set; }
        public string ShipAddress { get; set; }
        public string ShipCity { get; set; }
        public string ShipCountry { get; set; }
        public string ShipRegion { get; set; }
        public string ShipPostalCode { get; set; }

        [Filter(Order=2)]
        public Customer Customer { get; set; }
        [Filter(Order = 1)]
        public Employee Employee { get; set; }
        [Filter(Order = 3)]
        public Shipper Shipper { get; set; }

        public EntityCollection<Order_Detail> Order_Details { get; set; }
    }
}

Here you can see all three custom attributes in action.

• The HideColumnInAttribute hides columns in page templates (note the use of the ‘|’ OR operator to allows multiple pages to be selected.
• The ShowColumnOnlyInAttribute does the opposite and only shows columns in selected pages.
• The FilterAttribute here sets the order to display the filters on the list page (Note there are other properties on Filter that are not yet implemented).

Next up on NuGet are both of my original cascade and my hierarchical cascading field templates.
