手工绑定数据到GridView，并实现增、删、查、改，取消功能，切记：一定要在GridView
属性的“DataKeyNames”项中增加一个索引字段，如userid等，否则运行时会提示超出索引范围！！

ASP.NET——GridView控件绑定数据

        ASP.NET提供了许多种数据服务器控件,用于在Web页面中显示数据库中的表数据,GridView控件就是其中之一.这个控件和我们以前学过的DataGridView控件几乎是一样的,所以对GridView控件我们也并不陌生,下面简单介绍一下它的使用.         前台: 在工具箱中找到GridView控件,并把它拖拽到代码编辑区域.   第一步,进入设计界面,在GridView控件上方有一个向右的黑色小三角,单击这个按钮,选择编辑列,如图:          第二步,去掉自动

集合绑定数据

使用 ObservableCollection 列表控件主要是 ListBox.ListView.GridView 等. 为列表控件绑定数据不再是为 DataContext 属性赋值,应该使用列表控件自有的ItemsSource属性. 当列表数据元素由 ItemsSource绑定,就不能再动态操作(增删改) Items 属性 数据模板:

ASP.NET编辑与更新数据(非GridView控件实现)

Insus.NET在实现<ASP.NET开发,从二层至三层,至面向对象 (5)>http://www.cnblogs.com/insus/p/3880606.html 中,没有把数据编辑与更新功能一起演示,留下给网友们自由发挥,但是还是有网友想看看Insus.NET用实现方法. 以前Insus.NET的做法,是在GridView控件中进行.如这篇视频教程<GridView Edit Update Cancel Delete>http://www.cnblogs.com/insus/

WPF ListView点击删除某一行并获取绑定数据

最近在开发WPF程序时遇到一个问题,在gridview中希望实现在每一行最后添加一个删除的按钮,但是发现点击每行的button时只会触发button的点击事件,并没有选中这一行,此时调用list.SelectedItem时无法得到对应的绑定数据. UI.xaml<ListView x:Name="list" Height="494" Width="1121" FontSize="16" ><ListView.

关于angularJS绑定数据时自动转义html标签

折磨了两天,最后发现答案竟如此简单,不过辛苦还是值得的,毕竟为了弄明白这一点又学习了更多代码. angularJS在进行数据绑定时默认是会以文本的形式输出,也就是对你数据中的html标签不进行转义照单全收,这样提高了安全性,防止了html标签中的注入攻击,但有些时候还是需要的,特别是从数据库读取带格式的文本时,无法正常的显示在页面中. 而要对html进行转义,则要在数据绑定的html标签中使用ng-bind-html属性,该属性依赖与$sanitize,也就是需要引入angular-saniti
