Alvin thanks for replying, i tried what you said and i then got an error in
IE that said 'The server tag is not well formed.'. I think i may be missing
the binding bit, how do i test to make sure it is bound and there is data in
the DataSet?
Here is my code to save space i have only included what i believe to be
relevent if you need it all i can post it.
<%@ Page Language="VB" %>
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.SqlClient" %>
<script runat="server">
Dim ConnectionString As String =
"server=(local);database=commerce;trusted_connecti on=true"
Dim SQLCmd As String = "select CategoryID as [Cat ID], CategoryName as
[Cat Name] from CMRC_Categories"
Dim SQLDDL as String = "SELECT CategoryID, CategoryName FROM
CMRC_Categories"
Sub Page_Load(Sender As Object, E As EventArgs)
Dim myConnection As New SqlConnection(ConnectionString)
Dim myCommand As New SqlCommand(SQLCmd, myConnection)
myConnection.Open()
DataGrid1.DataSource =
myCommand.ExecuteReader(CommandBehavior.CloseConne ction)
DataGrid1.DataBind()
End Sub
Function GetCategories() as DataSet
Dim ddlDataSet as DataSet = New DataSet()
Dim myDataAdapter as SqlDataAdapter = New SqlDataAdapter(SQLDDL,
ConnectionString)
myDataAdapter.Fill(ddlDataSet, "Categories")
Return ddlDataSet
End Function
</script>

your complete code should look like this
dropdown.datatextfield = "CategoryID"
dropdown.datavaluefield="CategoryName"
then bind assuming you have tested the dataset to see if it is not null
and it has at least one row.
if this does not work for you, post your code

previously and tried it once more just to confirm but it still doesn't work, any
more ideas would be great.
