Question

I created a LINQ TO SQL project to connect with my database and I’d like to bind a list to a gridview in webforms.

If I add the property Browsable(false) in the designer.cs auto-generated code I can see the column disappear in the gridview.

If I, at the contrary, do something like

namespace InterfacesDAL
{
    [MetadataType(typeof(MasterMetadata))]
    public partial class InterfacesMasterLog : INotifyPropertyChanging, INotifyPropertyChanged
    {
        public class MasterMetadata
        {
            [Browsable(false)]
            public int InterfaceLogID;
        }

    }
}

Column is still showing on the gridview.

How should I fix this?

Checkout this tutorial on data annotations and I would recommend going through the entire MVC EF4 tutorial because it’s great!

GridView doesn’t have good support for Data Annotations. WebGrid (System.Web.Helpers.WebGrid) also doesn’t have complete support for Annotations.

I would suggest using MVCContrib Grid. Below is a good article on how to use it, including how to hide a column automatically [ScaffoldColumn(false)]
