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

此示例已解决如下： ASPX文件：

 <th runat="server">
                                    <asp:ImageButton ID="ImageButton1" runat="server"  Text="new" CommandName="new" ImageUrl="~/ADMIN/themes/Img/DeleteBtn.png" />
                                </th>

VB.net代码：

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
