두 번째 포스트 뒤로 버튼을 클릭 할 수 없습니다. OnClick

Question

모든 페이지 뒤에있는 MasterPage가있는 사이트를 만든 다음 동적으로 내 UserControls를로드하는 메뉴가있는 페이지를 만들고 그 안에 메뉴가있는 UserControl을 하나 만듭니다. 그 동적으로 다른 사람을로드 UserControls ...

내 문제는 : 내가 처음으로 OnClick 이벤트를 발생시킨 후 메뉴가있는 UserControl은 다시 발사 할 수 없다 ... 누군가가 그 이유를 알고 있습니까?

코드는 다음과 같습니다 :

페이지 :

public partial class AboutBrazil : BasePage 
{ 
    private String LastLoadedControl_AboutBrazil 
    { 
     get 
     { 
      if (ViewState["LastLoadedControl_AboutBrazil"] != null) 
      { 
       return ViewState["LastLoadedControl_AboutBrazil"].ToString(); 
      } 
      else 
      { 
       return "~/UserControl/AboutBrazil/ucIntroduction.ascx"; 
      } 
     } 
     set 
     { 
      ViewState["LastLoadedControl_AboutBrazil"] = value; 
     } 
    } 

    private void LoadUserControl() 
    { 
     UserControl userControl = (UserControl)Page.LoadControl(LastLoadedControl_AboutBrazil); 

     phAboutBrazil.Controls.Clear(); 
     phAboutBrazil.Controls.Add(userControl); 

     userControl.ID = "myUserControl"; 
    } 

    protected void Page_Load(object sender, EventArgs e) 
    { 
     this.SetTitulo("About Brazil"); 

     LoadUserControl(); 
    } 

    protected void btnLoadUserControl_Click(object sender, EventArgs e) 
    { 
     System.Drawing.Color foreColorI = System.Drawing.Color.FromArgb(102, 102, 102); 
     System.Drawing.Color foreColorA = System.Drawing.Color.FromArgb(27, 41, 13); 

     Button btnSender = (Button)sender; 

     btnIntroduction.ForeColor = foreColorI; 
     btnHistory.ForeColor = foreColorI; 
     btnThePeople.ForeColor = foreColorI; 
     btnBrazilianRegions.ForeColor = foreColorI; 
     btnBrazilianEcosystem.ForeColor = foreColorI; 
     btnGeneralInformation.ForeColor = foreColorI; 
     btnTips.ForeColor = foreColorI; 

     switch (btnSender.CommandArgument) 
     { 
      case "Introduction": 
       btnSender.ForeColor = foreColorA; 

       LastLoadedControl_AboutBrazil = "~/UserControl/AboutBrazil/ucIntroduction.ascx"; 
       break; 
      case "History": 
       btnSender.ForeColor = foreColorA; 

       LastLoadedControl_AboutBrazil = "~/UserControl/AboutBrazil/ucHistory.ascx"; 
       break; 
      case "The People": 
       btnSender.ForeColor = foreColorA; 

       LastLoadedControl_AboutBrazil = "~/UserControl/AboutBrazil/ucThePeople.ascx"; 
       break; 
      case "The Brazilian Regions": 
       btnSender.ForeColor = foreColorA; 

       LastLoadedControl_AboutBrazil = "~/UserControl/AboutBrazil/ucTheBrazilianRegions.ascx"; 
       break; 
      default: 
       btnSender.ForeColor = foreColorA; 

       LastLoadedControl_AboutBrazil = "~/UserControl/AboutBrazil/ucIntroduction.ascx"; 
       break; 
     } 

     this.LoadUserControl(); 
    } 
} 

첫 번째 사용자 제어 :

AsyncPostBackTrigger _Trigger = new AsyncPostBackTrigger(); 

_Trigger.ControlID = btnButton.ID; 
_Trigger.EventName = "Click"; 

this.upTheBrazilianRegions.Triggers.Clear(); 
this.upTheBrazilianRegions.Triggers.Add(_Trigger);
