Question : Hide submit button if datalist control is empty

I would like to hide a submit button if a DataList is empty. I don't really know the code. If you submit an answer please show me the code also. I have to do it in VB.Net. I googled and found the following code that I place in the code behind under the Page load event.

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim dv As DataList
        dv = SqlDataSource3.[Select](DataSourceSelectArguments.Empty)
        'Change DataSource name
        If dv.ToTable.Rows.Count = 0 Then

            Button1.Visible = False
        End If

What I am having a problem with is the To.Table. I get the following error. 'ToTable' is not a member of 'System.Web.UI.WebControls.DataList'. I tried to get smart and attempted to stick the button within the datalist itself but quickly found out that does not work. PLEASE HELP!

Answer : Hide submit button if datalist control is empty

to get the value then just use
string abbreviation = DropDownList1.SelectedValue;
