Question

在代码隐藏中设置弹出窗口的文本时遇到问题，它会刷新页面，这意味着弹出窗口会消失。

我尝试过一个示例/教程，但似乎无法让它发挥作用。我试过移动更新面板，并在按钮上使用autopostback = false。我确定它有点傻，但我无法看到它..

这是我的aspx页面;

constructor(
        protected route: ActivatedRoute,
        protected recipesService: RecipesService) {
        super(route)
    }

这是我的代码隐藏VB.NET;

<%@ Page Language="vb" AutoEventWireup="false" 
CodeBehind="ShowDialog.aspx.vb" Inherits="BootStrapDialog.WebForm1" 
MaintainScrollPositionOnPostBack="true" %>

根据您是否动态绑定模态，您有两种解决方案之一。

首先，您可以注册启动脚本，以便在页面重新加载时打开模式。

                Page.ClientScript.RegisterStartupScript(GetType(), "UpdateModal", string.Format("OpenModal(\"{0}\", \"{1}\");", "modal-blank", "static"), true);

我有一些框架来打开我的模态，但用引导模式打开代码替换javascript函数，它应该可以工作。

其次，您可以在Page_Load事件期间重新绑定模态。

基本上，一旦按下按钮，整个页面在触发按钮事件之前会再次经历它的生命周期。如果你没有绑定模态，页面就不知道它是否存在以设置文本。
