Denormalizing entities for binding to a grid?

What you have is a "has-a" relationship or a one-to-one navigation b.com/tag/property">property in A to B that you want to access in your DevExpress Grid. You can do this by b.com/tag/set">setting your FieldName b.com/tag/property">property to your NavigationProperty.FieldName

Say for a one-to-one relationship of Persont to Address like the following:

    public class Person
    {

      public int ID { get; b.com/tag/set">set; }
      public string FirstName { get; b.com/tag/set">set; }
      public string LastName { get; b.com/tag/set">set; }
      public virtual Address Address { get; b.com/tag/set">set; }
    }

    public class Address
    {
      public int ID { get; b.com/tag/set">set; }
      public string StreetAddress { get; b.com/tag/set">set; }
      public string City { get; b.com/tag/set">set; }
      public string State { get; b.com/tag/set">set; }
      public string Zip { get; b.com/tag/set">set; }

     }

Your GridView in your aspx b.com/tag/page">page to include both the Person and the StreeAddress b.com/tag/property">property of the Address navigation b.com/tag/property">property would look like this

        <dx:ASPxGridView ID="ASPxGridView1" runat="server">
        <Columns>
            <dx:GridViewDataTextColumn FieldName="FirstName" VisibleIndex="0">
            dx:GridViewDataTextColumn>
            <dx:GridViewDataTextColumn FieldName="LastName" VisibleIndex="1">
            dx:GridViewDataTextColumn>
            <dx:GridViewDataTextColumn FieldName="Address.StreetAddress" VisibleIndex="1">
            dx:GridViewDataTextColumn>
        Columns>
    dx:ASPxGridView>

In this case, Person being table A and Address being table B. You are binding your gridview on A so then you would be b.com/tag/set">setting your field name to B.FieldToDisplay.

Hope this helps!
