问题 I am using both material design and dragablz:TabablzControl in WPF MVVM application.Material design is used to style button and text box. Grid is located inside tab control.After loading bulk data in to data grid I am facing below design issues. it does not show scroll bar. I have tried with scroll viewer though it didn't work. Actually I can scroll down using arrow key and mouse scroll. But the scroll bar is not visible. When we click on a single row of the data grid that row become

How should I move a WPF Window using MVVM?

问题 This is probably overkill on the MVVM pattern but it's new to me and I'm interested to see if it is possible. If I attach to the MouseMove event for a Window and do DragMove, I can move a bordeless window. Can I achieve this by some other method in MVVM or should I just accept adding this code to the Window's codebehind? 回答1: This is pure UI logic and doesn't belong in a ViewModel. The only reason you wouldn't want to put this in your code-behind would be for re-use and that is better solved

Vue简单介绍

Vue(Vue.js的简称)是前端的主流框架之一,和Angular.js、React.js一起,成为前端三大主流框架,Vue.js是一套构建用户界面的框架, 只关注视图层 ,它不仅容易上手,还便于与第三方库或既有项目整合(Vue有配置的第三方类库,可以整合起来做大型项目的开发)。 先来说明几个概念: 框架和库的区别: 框架是一套完整的解决方案,对项目侵入性大,项目如需更换框架,则需重新架构整个项目 库(插件)提供一个小功能,对项目的侵入性较小,如果某个库无法完成某些需求,可以很容易的切换到其他库来满足需求 MVC和MVVM: MVC(模型(model)-视图(view)-控制器(controller)),model是数据管理者,要么是数据库中存储的数据,要么是从服务器中获取的数据;view是用户在屏幕上看到的结构、布局和外观;将两者联系起来的是controller,通过controller将model里的数据放到view中,或从view中获取数据存入model。 MVVM(Model-View-ViewModel),model是与view界面对应的数据对象,view是用户在屏幕上看到的结构、布局和外观,ViewModel是一个绑定器,在view和model之间进行通信。 vue基本代码与MVVM之间的对应关系: < body > <!--vue实例所控制的这个元素区域

上一篇写 数据绑定 的文章,写到最后留了一个坑。当子组件绑定父组件的一个字段,并且子组件修改它的时候父组件不能实时进行同步更新UI的问题,最近终于在 Blazui 作者的指导下搞定了。 UserInfo类要实现INotifyPropertyChanged接口 public class UserInfo: INotifyPropertyChanged { private string _userName; public string UserName { get { return _userName; } set { _userName = value; PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(UserName))); } } public string Sex { get; set; } public DateTime BrithDay { get; set; } public event PropertyChangedEventHandler PropertyChanged; } 没想到微软blazor还是借用了WPF搞MVVM的模式,模型需要实现INotifyPropertyChanged类,在属性发生修改的时候可以发出通知。 父组件订阅PropertyChanged事件: @page

vue是一个渐进式的javascript,可以将vue作为你应用的一部分嵌入其中,带来更丰富的交互体验,也可以使用更多的vue核心库去进行开发。 vue是一个轻量级的mvvm框架,通过数据驱动和组件化进行前端开发,通过简单的api就能实现响应式的数据绑定和组合的视图组件。 首先要导入vue 的js <script src="vue-2.4.0.js"></script> 1. < body > < div id = "app" > < h2 > Hello {{name}} </ h2 > </ div > </ body > <script> let app= new Vue({ el: '#app', date:{ name: 'Vue' } }) </script> 1.创建一个vue对象,浏览器内存中就有一个vue 2.创建vue的时候,传入一个参数,这个参数是一个对象options 3.参数中有el属性,该属性决定了这个vue对象挂载到哪一个元素上。 4.参数中有date属性,该属性定义存储大部分的数据,这些数据可以自己直接定义,也可以从网络中获取。 2.vue列表循环显示 <body> < div id = "app" > < ul > < li v-for = "item in books" > {{item}} </ li > </ ul > </ div > </
