支持动态加载.xap，面向插件开发
-
RapidSL.SL.App.Portal提供主框架的UI逻辑，只需要开发自己的App，如RapidSL.SL.App.Main
- 然后配置菜单：
1 < sdk:TreeViewItem Header ="产品管理" IsExpanded ="True" >
2 < controls:AdminMenuItem Id ="1" Margin ="2" Content ="ProductEdit" NavigateView ="RapidSL.SL.App.Main.xap/Product.Index" ViewPermission ="ProductView" />
3 < controls:AdminMenuItem Id ="2" Margin ="2" Content ="CategoryEdit" NavigateView ="RapidSL.SL.App.Main.xap/Category.Index" ViewPermission ="CategoryView" />
4 </ sdk:TreeViewItem >NavigateView="RapidSL.SL.App.Main.xap/Product.Index"将调用XapHost控件从服务端下载动态加载NavigateView="RapidSL.SL.App.Portal.Admin"将调用当前程序集的控件 -
XapHost控件提供动态下载.xap及加载
1 public XapHost( string xapUri, string viewName = null)
2 {
3 InitializeComponent();
4
5 this.FileName = xapUri;
6
7 var xapLoad = new XapLoader(xapUri);
8 xapLoad.DownloadProgressChanged += (s, e) =>
9 {
10 this.TotalSize = (e.TotalBytesToReceive * 1d / 1024 / 1024).ToString( " 0.00 ");
11 this.Percentage = e.ProgressPercentage;
12 };
13
14 xapLoad.LoadCompleted += (s, e) =>
15 {
16 this.Content = e.Element;
17 };
18
19 xapLoad.LoadControl( null, viewName);
20 }
对Resource的支持
- 找到所有标识有 StaticResourceAttribute的类，然后创建相关实例，并注入到Application.Resources，相当于在 App.xaml里手写资源
- 实现了资源管理器对资源进行注入管理

键盘Enter键提交表单
- 使用AttatchProperty实现传统Html表单的键盘Enter提交
1 < Grid x:Name ="LayoutRoot" core:AttachProperties.SubmitButton =" {Binding ElementName=submit} " >
2 < Button x:Name ="submit" Content ="登录" Margin ="20,0,20,0" Padding ="20,0,20,0" Command =" {Binding UserLogin} " />
3 </ Grid >
- 具体绑定按钮和键盘事件
1 #region SubmitButton AttachProperty
2 public static object GetSubmitButton(DependencyObject obj)
3 {
4 return ( object)obj.GetValue(SubmitButtonProperty);
5 }
6
7 public static void SetSubmitButton(DependencyObject obj, object value)
8 {
9 obj.SetValue(SubmitButtonProperty, value);
10 }
11
12 // Using a DependencyProperty as the backing store for SubmitButton. This enables animation, styling, binding, etc...
13 public static readonly DependencyProperty SubmitButtonProperty =
14 DependencyProperty.RegisterAttached( " SubmitButton ", typeof( object), typeof(AttachProperties), new PropertyMetadata(SubmitButtonChanged));
15
16 private static void SubmitButtonChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
17 {
18 var button = (ButtonBase)e.NewValue;
19 var form = d as UIElement;
20 form.KeyDown += (s, se) =>
21 {
22 if (se.Key == Key.Enter)
23 {
24 button.Focus();
25 if (button.Command != null)
26 button.Dispatcher.BeginInvoke(()=> button.Command.Execute( null));
27 }
28 };
29 }
