if { 
    this.showhide.ImageUrl = "../common/images/hide-icon.png"; 
    this.showhide.AlternateText = "Hide SearchBar"; 
    this.searchBar.Visible = false; 
    Session["showHideImage"] = "hide"; 
    ScreenProjectSearch ProjSearch = CurrentProjectSearch; 
    lblTypeOfSearch.Text = "Search results are based on"; 
    string typeOfSearch = string.Empty; 

    if (CurrentProjectSearch != null) 
    { 
    //lblTypeOfSearch.Text = "Search results are based on"; 

    if (CurrentProjectSearch.IsFileName) 
     typeOfSearch += " Filename " + ProjSearch.TextSearch.Trim(); 
    if (CurrentProjectSearch.IsDescription) 
     typeOfSearch += " Description " + ProjSearch.TextSearch.Trim(); 
    if (CurrentProjectSearch.IsPartNumber) 
     typeOfSearch += " PartNumber " + ProjSearch.TextSearch.Trim(); 
    if (CurrentProjectSearch.IsState) 
    { 
     if (CurrentProjectSearch.IsDevelopment) 
     typeOfSearch += " Development State "; 
     if (CurrentProjectSearch.IsValidation) 
     typeOfSearch += " Validation State "; 
     if (CurrentProjectSearch.IsValidationPendingApproval) 
     typeOfSearch += " ValidationPendingApproval State "; 
     if (CurrentProjectSearch.IsPilot) 
     typeOfSearch += " Pilot State "; 
     if (CurrentProjectSearch.IsFactory) 
     typeOfSearch += " Factory State "; 
     if (CurrentProjectSearch.IsCancel) 
     typeOfSearch += " Cancel State "; 
    } 
    if (CurrentProjectSearch.IsDate) 
     typeOfSearch += " Created Date From: " + ProjSearch.FromDate + " To: " + ProjSearch.ToDate; 
    if (CurrentProjectSearch.IsPromoteDate) 
     typeOfSearch += " Promoted Date From: " + ProjSearch.FromPromoteDate + " To: " + ProjSearch.ToPromoteDate; 
    if (CurrentProjectSearch.IsCreatedBy) 
     typeOfSearch += " Created By: " + ProjSearch.CreatedBy.ToString(); 
    if (CurrentProjectSearch.IsProjectIDs) 
     typeOfSearch += " PrjoectIds: " + ProjSearch.ProjectIDs; 
    if (CurrentProjectSearch.IsWorkFlow) 
    { 
     if (CurrentProjectSearch.IsMdiagsNormal) 
     typeOfSearch += " WorkFlow: " + "Mdiags Normal"; 
     if (CurrentProjectSearch.IsMdiagsTestEngineer) 
     typeOfSearch += " WorkFlow: " + "Mdiags TestEngineer"; 
    } 
    if (!string.IsNullOrEmpty(typeOfSearch)) 
    { 
     lblTypeOfSearch.Text += typeOfSearch; 
     lblTypeOfSearch.Visible = true; 
    } 
    } 
}

我想如果一些文本追加到它時，typeOfSearch不爲空，在Page_Load顯示此lblTypeOfSearch。如果我檢查Page_Load中的值，它在那裏顯示爲空。我怎樣才能利用這個變量來顯示？

只是調試巨獸，看看實際發生了什麼... – walther 2014-09-06 08:29:24

此代碼是在按鈕單擊。標籤在按鈕點擊事件中添加文本。如果我想再次使用相同的文本，我如何在頁面加載方法中使用它？ – user3356020 2014-09-06 08:42:38

每當用戶點擊某件東西並且不在客戶端處理時，就會有一個請求發送到服務器，並且它返回一個新頁面，其新實例化代碼隱藏。所以，如果你想在回發期間持續數據，返回頁面等，你需要先將它存儲在某個地方（session，db，無論...），然後你可以在Page_Load中訪問它。

請記住，網站是無國籍的。

正如我所見，您的代碼必須正常工作，您是否可以看到緩存的結果，在這種情況下，您可以按Ctrl + F5鍵查看您的新代碼結果。如果你想在按鈕點擊和表單加載時訪問你的文本，你可以聲明你的字符串變量是全局的（超出這些方法）。

全局變量？ YUCK！他們足夠邪惡，但要在網絡編程中推廣他們？肯定是一個不 - 不，先生！ – walther 2014-09-06 08:49:58

謝謝，但在網頁編程中，我們可以在JavaScript中使用全局變量的相同功能。或者如果我們不得不做這個服務器端，我們可以做一個額外的隱藏輸入。 – Nabi 2014-09-06 09:30:54

加載新頁面時，JavaScript如何保持數據？（這是當Page_Load被調用時） – walther 2014-09-06 10:05:58
