Is it good to put them in to an array and them to a store procedure. <br />
<br />
If the user clicks 20 items, then I would have to do 20 inserts. That doesn't sound too efficient. <br />
<br />
The code I have for finding the checked items is below<br />
<CODE> Dim i As Integer<br />
        Dim strChecked As String<br />
<br />
        For i = 0 To Me.chkLstSecurityRoles.CheckedItems.Count - 1<br />
<br />
            strChecked = Me.chkLstSecurityRoles.CheckedItems(i).ToString()<br />
