如何在搜索按鈕后禁用主表單？

Question

**

這是我的搜索按鈕代碼，我想在搜索注冊后禁用母版頁**

try
            {
                signUp signUp = new signUp();
                signUp.Username = txtUserName.Text;
                Session["user"] = signUp.Authentication();
                Response.Redirect("BooksInformation.aspx");
                
            }
            catch (Exception ex)
            {
                lblOutput.Text = ex.Message;
            }

Answer 1

假設在母版頁中你有這樣的東西：

<a href="Student.aspx">Students</a>

為標簽添加runat="server"和id屬性

<a href="Student.aspx" id="studentLink" runat="server">Students</a>

然后在BooksInformation.aspx的Page_Load事件中確保用戶已登錄並隱藏鏈接：

var studentLink = Master.FindControl("studentLink") as HtmlControl;
studentLink.Visible = false;
