Hello,

If the listbox is in the usercontrol then you need to make a public property
on the usercontrol that you use to set the selectedItem property of the
listbox in the user control. Like this:

In your usercontrol do this:

Public Class WebUserControl1
   Inherits System.Web.UI.UserControl
   Protected WithEvents listbox1 As ListBox
   Private m_selectedValue As String = String.Empty

   Public Property SelectedValue() As String
       Get
           Return m_selectedValue
       End Get
       Set(ByVal Value As String)
           m_selectedValue = Value
       End Set
   End Property
   Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
       'Load you listbox here

       For Each item As ListItem In listbox1.Items
           If item.Value = m_selectedValue Then
               item.Selected = True
               Exit For
           End If
       Next
   End Sub

End Class

Now in your web page you can set the seletedValue property like this:

Protected WithEvents myUserControl As WebUserControl1 'This is your
usercontrol
 'This code goes in the Page_Load event

 yourUserControl.SelectedValue = Session("MySessionKey")

I would stay way from using the session state for something like this.  You
find that a querystring would work better in this situation.

Let me know if you have any questions.

Hi,

You can use following example code in your user control's load event:

       for (int i = 0; i < ddl1.Items.Count; i++)
       {
           if (ddl1.Items[i].Text == "2")
           {
               ddl1.SelectedIndex = i;
               break;
           }
       }

Note you'd better use SelectedIndex to set the selected item rather than
set an item's Selected property, it will cause error when two items both
have Selected property set to true.
