Add Checkbox in markup
<asp:CheckBox ID="ChkSelect" runat="server" />
code behind as follows:
Dim ChkSelect As CheckBox = Nothing
Dim ListItem As ListViewDataItem = Nothing
Dim ItemList As List(Of Person) = New List(Of Person)
Dim Item As Person= Nothing
For Each ListItem In MyDataList.Items
ChkSelect = ListItem.FindControl("ChkSelect")
If ChkSelect.Checked Then
Dim UIN As Integer = _
MyDataList.DataKeys(ListItem.DisplayIndex).Value.ToString()
Item = Persons.GetData(UIN)
Item.Deleted = True
ItemList.Add(Item)
End If
Next
Data = Persons.UpdateBulk(ItemList)
If Data = True Then
BindMyData()
End If

You need to create a template for the items in the ListView, put the checkbox in it, and then get all the items that were checked when you click the Delete button. You could either keep track of the selected items on the client or the server, but it would always require some work to persist them.
Here's an article on using templates with the ListView: http://msdn.microsoft.com/en-us/library/bb398790.aspx#CreatingTemplatesForTheListViewControl
