我们在Prism中弹出一个对话框,默认是一个Windows默认样式的窗口,这样会同自己所开发的项目完全不搭调,譬如下面这样子

那么如果为了配合软件主体的风格,可以做出类似这样效果

其实原理也很简单,Prism也考虑到了这一点,所以特意设计一个供用户自定义的接口

1、新建一个Window视图

注意Window里的一些必要属性记得设置一下,比如SizeToContent ShowInTaskbar等等实现无边框还是使用常规WindowChrome做法
- <WindowChrome.WindowChrome>
- <WindowChrome
- CaptionHeight="60"
- CornerRadius="0"
- GlassFrameThickness="0" />
- </WindowChrome.WindowChrome>
其中CaptionHeight表示可以拖拽的高度,这里一般建议与自己所设计的高度一致,关于WindowChrome相关用法和介绍就不过多赘述,具体可前往MSDN文档:WindowChrome 类
2、根据自己需求或设计图重写该窗体样式,XAML太多就不一一介绍了,直接上代码
- <Window
- x:Class="使用Prism弹出自定义窗体样式的对话框.Components.DialogWindowView"
- xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

Tips:因为一般对话框分为标题栏和主体部分,所以我们可以使用Grid分为两行,第一行是标题,第二行是内容,使用ContentPresenter来承载要显示的用户控件

1、将自定义的样式组件注入到IOC容器
- protected override void RegisterTypes(IContainerRegistry containerRegistry)
- {
- containerRegistry.Register
(nameof(DialogWindowView)); - }
2、使用DialogService弹出对话框
- private void CustomOpenDialog()
- {
- DialogParameters dialogParameters = new DialogParameters()
- {
- {"Title",$"忧郁的蛋 {DateTime.Now:yyyy-MM-dd}" }
- };
- dialogService.Show(nameof(TestDialogView), dialogParameters, result =>
- {
-
- }, nameof(DialogWindowView));
- }
这段与传统打开弹框是差不多,唯一不同的就是使用到了一个可传入WindowName的重载函数,Tips:我们自定义的这个组件(DialogWindowView)是一定需要注入到IOC容器的,不然拿不到这个实例就会抛出异常,另外还有一个点就是该组件还需继承自IDialogWindow

效果
