Answer 1

<asp:Button runat="server" ID="cmdInsert" CommandName="Insert" Text="Insert" />
Protected Sub ListView1_ItemInserting (ByVal sender As Object, ByVal e as ListViewEditEventArgs)
' ... '
End Sub

Answer 2

this example has been solved like this :
ASPX file:
<th runat="server">
<asp:ImageButton ID="ImageButton1" runat="server" Text="new" CommandName="new" ImageUrl="~/ADMIN/themes/Img/DeleteBtn.png" />
</th>
the VB.net Code:
Sub deletedd(ByVal sender As Object, ByVal e As ListViewCommandEventArgs) Handles ListView1.ItemCommand
Try
If e.CommandName.Equals("Delete") Then
'this to take a value from any control
Dim Idlabel As Label = e.Item.FindControl("ImageIDLabel")
Session("ID") = Idlabel.Text()
End If
If e.CommandName.Equals("new") Then
'Other code
ListView1.InsertItemPosition = InsertItemPosition.FirstItem
End If
If e.CommandName.Equals("Cancel") Then
'Other code
ListView1.InsertItemPosition = InsertItemPosition.None
End If
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
