page reloads

[Guest]

I have the following code to populate a list box when my form opens. The
problem is that when I select something from the listbox the page reloads and
goes to the top of the page. I need it to not do that so that I can finish
filling out the form and then hit submit button.

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
strconnectionstring = "Provider=sqloledb;data
source=ntserver3;initial catalog=Family_Consultation_test;user
id=sa;password=guru;"
objoledbconnection = New OleDb.OleDbConnection(strconnectionstring)
objoledbcommand = New OleDb.OleDbCommand
objoledbcommand.Connection = objoledbconnection
objoledbcommand.Connection.Open()
strsql = "select first_name + ' ' + last_name as fullname from
viewpractitioner where pers_org_term_date is null" & _
" and pract_entity_id < '800.033' or pers_org_term_date is
null and pract_entity_id > '908.033' order by last_name"
objoledbcommand.CommandText = strsql
objoledbdatareader = objoledbcommand.ExecuteReader
Me.ddlClinician.DataSource = objoledbdatareader
If Not Page.IsPostBack Then
Me.ddlClinician.DataBind()
ddlClinician.Items.Insert(0, " ")
ddlClinician.SelectedIndex = 0
objoledbdatareader.Close()
'objoledbcommand.Connection.Close()
End If
objoledbdatareader.Close()
strsql = "select * from tblMedicalNecessity"
objoledbcommand.CommandText = strsql
objoledbdatareader = objoledbcommand.ExecuteReader
lstMedNecess.DataSource = objoledbdatareader
'If Not Page.IsPostBack Then
lstMedNecess.DataBind()
lstMedNecess.Items.Insert(0, " ")
lstMedNecess.SelectedIndex = 0
'objoledbdatareader.Close()
'objoledbcommand.Connection.Close()
'End If
objoledbdatareader.Close()
objoledbcommand.Connection.Close()
End Sub

Is the AutoPostBack property of the ListBox control set to true?

If so, it should be set to false to achive the behavior you desire.
