Dim ds As New System.Data.DataSet()

Private Sub Page_Load(ByVal sender As System.Object,ByVal e As System.EventArgs)Handles MyBase.Load

If(Me.IsPostBack)Then Return

CreateDataSet()
FpSpread1.Sheets(0).DataSource=ds
FpSpread1.Sheets(0).DataMember="names"
FpSpread1.Sheets(0).DataKeyField="first"

Dim dm As FarPoint.Web.Spread.Model.DefaultSheetDataModel=CType(FpSpread1.ActiveSheetView.DataModel,FarPoint.Web.Spread.Model.DefaultSheetDataModel)
ListBox1.Items.Add(dm.GetKey(0))
End Sub

Private Sub CreateDataSet()
Dim names As DataTable
names=ds.Tables.Add("names")
names.Columns.Add("first")
names.Columns.Add("last")
names.Columns.Add("index")
names.Rows.Add(New Object(){"bob","morris",0})
names.Rows.Add(New Object(){"sean","morris",1})
names.Rows.Add(New Object(){"chris","morris",2})
End Sub

System.Data.DataSet ds=new System.Data.DataSet();

private void Page_Load(object sender,System.EventArgs e)

FpSpread1.Sheets[0].DataKeyField="first";

FarPoint.Web.Spread.Model.DefaultSheetDataModel dm=(FarPoint.Web.Spread.Model.DefaultSheetDataModel)FpSpread1.ActiveSheetView.DataModel;
ListBox1.Items.Add(dm.GetKey(0).ToString());
}

private void CreateDataSet()
{
