Datagrid Paging Question

If i have a datagrid and want to implement paging, i can do it and it shows correctly on the rendered web page. But if i click on the numbers to go to the next page, i get a page not found, i am assuming i have to add the code to go to the next set of records, and ideas how to do that? In C#?

example..in VB..sorry but ahould be simple to convert to c#

Code:

---

<asp:DataGrid id="gridCorpList" runat="server" AllowPaging="True" OnPageIndexChanged="gridCorpList_Page" Width="100%" PageSize="5" ShowHeader="False" GridLines="None">
        <PagerStyle mode="NumericPages"></PagerStyle>
    </asp:DataGrid>

---

Code:

---

Sub gridCorpList_Page(source As Object, e As DataGridPageChangedEventArgs)
        gridCorpList.CurrentPageIndex = e.NewPageIndex
        strSQL= "Select Corp_Name FROM Corporations Where id <> 1 ORDER BY Corp_Name"
        myConn = New OleDbConnection (strConnString)
        ' Populate the Dataset from the SQL statement
        ' Run the Sql statement and get the Data into the DataAdapter
        myCommand = New OleDbDataAdapter(strSQL, myConn)
        ' Fill the DataSet and name the table
        myCommand.Fill(myDS, "Corp")
        myConn.Close()
   
        gridCorpList.DataSource = myDS.Tables("Corp").DefaultView
        gridCorpList.DataBind()
    End Sub
