Dropdownlist value remove in Listbox

[NBercasio]

My dropdown and listbox got the same values. If I choose a value in my
dropdown, i want this value to be removed from my listbox.

So far I have this but it is not working...

CODE BEHIND:

Public Sub ddldeptowner_SelectedIndexChanged(ByVal sender As
Object, ByVal e As System.EventArgs) Handles
ddldeptowner.SelectedIndexChanged
Dim LI As ListItem
Dim index As String
index = ddldeptowner.SelectedItem.Value
For Each LI In lstboxadddept.Items
lstboxadddept.Items.Remove(index)
Next
End Sub

WEBFORM:

<asp:dropdownlist Runat="server" ID="ddldeptowner" AutoPostBack=True
OnSelectedIndexChanged="ddldeptowner_SelectedIndexChanged"></asp:dropdownlist>

What you are doing will remove all of the items from the drop down; instead of looping over the items, try:

lstboxadddept.Items.RemoveAt(index)

And get rid of the For Each LI In... you can also call lstboxaddept.Items.FindByValue(ddldeptowner.SelectedItem.Value) to find the particular item you are interested in.
