DataGrid Edit command problems

[Fizikas]

Hi,

I’m trying to use Datagrid edit feature. When I press Edit button Datagrid shows Update and Cancel buttons, but I still can’t see text boxes. Please take a look at my code and say where is the problem.

P. S. Sorry for my English

Dim cSQConnection As SqlConnection
    Dim cSqlCommand As SqlCommand
    Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not Page.IsPostBack Then
            BindData()
        End If
    End Sub
    Sub BindData()
        cSQConnection = New SqlConnection("server=MySQLServer;database=MyDatabase;")
        cSQConnection.Open()
        cSqlCommand = New SqlCommand("SELECT * FROM Projects", cSQConnection)
        DataGrid1.DataSource = cSqlCommand.ExecuteReader()
        DataGrid1.DataBind()
    End Sub
    Private Sub DataGrid1_EditCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.EditCommand
        DataGrid1.EditItemIndex = e.Item.ItemIndex
        BindData()
    End Sub
