不管是Button or LinkButton...皆有CommandName & CommandArgument屬性，可產生各別Click事件去傳遞值
若同一頁面上之Button皆有相同的行為，則可設定其OnCommand屬性來連結後端觸發事件，並利用CommandName & CommandArgument來傳遞設定值
例如：
前端程式碼
<asp: LinkButton ID ="lkb01" runat ="server" OnCommand ="FuncGo" CommandName="R1_001"></asp :LinkButton>
後端程式碼
Protected Sub FuncGo(sender As Object, e As CommandEventArgs)
Select Case e.CommandName
Case "R1_001"
'do somthing
Case Else
End Select
End Sub
