problem with combobox

using mircosoft visual basic .net on smart application device,plaform is pocket pc..
i tried using ' ComboBox2.Items.Insert(0, "-- Choose --") ' to make it as default,but it jjuz display my 1st record of my database..anyone idea why??

Here's my code..
Dim dsn As String
Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


'determine which server and database to use
dsn = "server = 198.0.0.91; uid=sa; pwd=; database=Boxoffice"
Dim myConnection As SqlConnection = New SqlConnection()
myConnection.ConnectionString = dsn
Dim da As SqlDataAdapter = New SqlDataAdapter("Select * from Book", myConnection)
' create a new dataset
Dim ds As DataSet = New DataSet()
' fill dataset
da.Fill(ds, "Book")

' Attach DataSet to ComboBox2

ComboBox2.DataSource = ds.Tables(0)
ComboBox2.DisplayMember = "Date"
ComboBox2.Items.Insert(0, "-- Choose --")



End Sub

Doesn't work that way unfortunately, either you load your combobox yourself or you use a datasource, if the latter it uses the records in the dataset no matter what.

Include the "-- Choose --" in the SELECT statement using a union.

VB Code:

Dim da As SqlDataAdapter = New SqlDataAdapter("SELECT '-- Choose --' As date " _
  & " UNION Select Date  from Book", myConnection) 
' create a new dataset 
Dim ds As DataSet = New DataSet() 
' fill dataset 
da.Fill(ds, "Book") 
 
' Attach DataSet to ComboBox2 
 
ComboBox2.DataSource = ds.Tables(0) 
ComboBox2.DisplayMember = "Date"

The select statement will expose a dataset with "-- Choose --" as the first item. Hope this works.

thanks...but i've decided to load combobox myself ..ive tried all the code ,kept getting the same error whenever i add "ComboBox2.Items.Insert(0, "-- Choose --") " or
ComboBox2.Items.Add(0, "-- Choose --")
