Glossary Item Box

You can use a wide variety of data-sources for grid structure generation (the only requirement is that these custom objects implement the ITypedList/IEnumarable/ICustomTypeDescriptor interfaces). Furthermore, Telerik RadGrid supports binding to list of custom objects with Nullable properties (.NET 2.0 feature). For more details please refer to the code snippets below:

ASPX/ASCX Copy Code
<rad:RadGrid id="RadGrid2" runat="server">
    <MasterTableView AutoGenerateColumns="True">
    </MasterTableView>
</rad:RadGrid>

And in the code-behind:

C# Copy Code
protected void RadGrid2_NeedDataSource(object source, Telerik.WebControls.GridNeedDataSourceEventArgs e)
{
           ArrayList list = new ArrayList();
           list.Add( new TestListItem( "Item 0", 0) );
           list.Add( new TestListItem( "Item 1", 0 ) );
           list.Add( new TestListItem( "Item 2", 1 ) );
           list.Add( new TestListItem( "Item 3", 1 ) );
           list.Add( new TestListItem("Item 4", null));

           this.RadGrid2.DataSource = list;
}
public class TestListItem
{
        private string _a;
        private int? _b;

        public TestListItem( string a, int? b )
       {
           this._a = a;
           this._b = b;
       }

        public string A
       {
            get
           {
                return this._a;
           }
            set
           {
               this._a = value;
           }
       }

        public int? B
       {
            get
           {
                return this._b;
           }
       }
}
VB.NET Copy Code
Private Sub RadGrid2_NeedDataSource(ByVal [source] As Object, ByVal e As GridNeedDataSourceEventArgs) Handles RadGrid2.NeedDataSource
             Dim list As New ArrayList
            list.Add( New TestListItem("Item 0", 0))
            list.Add( New TestListItem("Item 1", 1))
            list.Add( New TestListItem("Item 2", 2))
            list.Add( New TestListItem("Item 3", 3))
            list.Add( New TestListItem("Item 4", Nothing))

             Me.RadGrid2.DataSource = CType(list, IEnumerable)
End Sub
Public Class TestListItem
         Private _a As String
         Private _b As Nullable(Of Integer)


         Public Sub New(ByVal a As String, ByVal b As Nullable(Of Integer))
             Me._a = a
             Me._b = b
         End Sub

         Public Property A() As String

             End Set
         End Property

         Public ReadOnly Property B() As Nullable(Of Integer)
             Get
                 Return Me._b
             End Get
         End Property
