Question

I’ve got a GridView :

<asp:GridView ID="grdRestitutions" runat="server" AutoGenerateColumns="False">
 <Columns>
  <asp:BoundField DataField="JobNumber" HeaderText="Job" />
  <asp:BoundField DataField="ContainerType" HeaderText="Type" />
  <asp:BoundField DataField="ReleaseDate" HeaderText="Date" />
  <asp:BoundField DataField="Commodity" HeaderText="Commodity" />
  <asp:BoundField DataField="GrossWeight" HeaderText="Weight" />
  <asp:BoundField DataField="SpecialInstructions" HeaderText="Special Instructions" />
 </Columns>
</asp:GridView>

That I’m trying to set the DataSource to be a List<Restitution>() where Restitution is a public structure consisting only of public members; i.e.:

public struct Restitution
{
    public int ContainerReleasesId;
    public int ContainerId;
    public System.DateTime ReleaseDate;
    public int DepotId;
    public string DepotName;
    public string JobNumber;
    public string BillOfLadingNumber;
    public string BookingType;
    public string Commodity;
    public string SpecialInstructions;
    public int GrossWeight;
    public bool Confirmed;
    public bool RecievedFlag;
    public bool ReleaseSource;
    public int ContainerTypeId;
    public string InOut;
    public string ContainerTypeDescription;
}

The data binding looks fairly innocuous, too:

grdRestitutions.DataSource = restitutions;
grdRestitutions.DataBind();

However, an exception is thrown on the DataBind() statement with the less than helpful message of:

“A field or property with the name ‘JobNumber’ was not found on the selected data source.”

I don’t understand why this isn’t working; whilst most examples and use cases seem to use DataSets it does appear that it should support objects implementing IEnumerable. Is there anything special I have to do to allow it to work?

Answer 1

Convert all public fields for public properties and it should work.

public struct ContainerRelease
{
    public int ContainerReleasesId {get; set;} 
    public int ContainerId {get; set;} 
    public System.DateTime ReleaseDate  {get; set;} 
    ...
}
