當button_click事件顯示用戶控件

Question

我想在button_click事件時顯示用戶控件。

用戶控逆變declartion是

<div id="divloginUControl" runat="server"> 
    <td></td> 
     <td> 
     <LUC:LoginLoader ID="loginUserControl" runat="server" /> 
     </td> 
</div> 

我與

protected void Page_Load(object sender, EventArgs e) 
    { 

     loginUserControl.Visible = false; 
    } 

protected void Button1_Click(object sender, EventArgs e) 
    { 
     loginUserControl.Visible = true; 

     System.Threading.Thread.Sleep(5000); 
     ScriptManager1.RegisterPostBackControl(Button1); 
     string result = asset.UserLogin(txtloginid.Text, txtpassword.Text); 
     if (Convert.ToInt32(result) == 1) 
     { 
      Session["uname"] = txtloginid.Text; 
      Server.Transfer("CreatedInventory.aspx"); 
     } 
     else 
     { 
      pwdinfo.Text = "Please enter correct password"; 
      txtpassword.Focus(); 
     } 
    } 

嘗試，但它不能正常工作，請給一些suggetions

哦心動不如試試這個

protected void Page_Load(object sender, EventArgs e) 
{ 
    if(!Page.IsPostback) 
    { 
     loginUserControl.Visible = false; 
    } 
}
