RESOLVED***Problems with asp.net

hi!

i have a problem with .net. i wanna know why does the
page reload itself after i've clicked a button. & also
how come i cant see all my data in a dropdown list.
see code below


While reader.Read
'populate role datalist
tmpRole = reader("role_descr")
dlRoles.Items.Add(tmpRole)
End While


and also when i add a to datalist nothing happens


tmpRole = dlRoles.SelectedItem.Value
lstEmpRoles.Items.Add(tmpRole)




thanx

You will want to only populate the data for the first load...

so...

VB Code:

Private Sub Page_Load (...
 
 If Not IsPostBack Then
  'Load your data into your dropdowns
 End If
 
End Sub

As far as not seeing all your data in your datalist, you are probably suffering from object conversion errors, but without Option Strict enabled, you have become unaware of them.

OR

Preferably, you should simply set the datasource to your reader, and call DataBind on the datalist.

VB Code:

Dim dr As System.Data.SqlClient.SqlDataReader = SqlCommand1.ExecuteReader(CommandBehavior.CloseConnection)
 
DataList1.DataSource = dr
DataList1.DataBind()
dr.Close()
