本篇內容主要講解“DevExpress怎么創建Blazor Dashboard應用”,感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷,實用性強。下面就讓小編來帶大家學習“DevExpress怎么創建Blazor Dashboard應用”吧!
重要提示:請注意,沒有Blazor的本地Dashboard UI組件,您只能將客戶端JavaScript Dashboard控件集成到Blazor應用程序中。
本教程描述了如何將JavaScript Dashboard控件集成到Blazor應用程序中。
先決條件
帶有ASP.NET和Web開發工作負載的Visual Studio 2019
.NET Core 3.1 或更高版本
DevExpress Universal Subscription v20.2
創建Blazor應用程序
此解決方案使用ASP.NET Core后端(服務器端Blazor)來處理來自JavaScript儀表板的請求,客戶端定義了此組件的UI以及響應UI更新所需的邏輯。
1. 創建一個名為BlazorDashboardApp的新Blazor應用程序。 選擇Blazor WebAssembly App模板,并啟用ASP.NET Core hosted復選框。
Alternative. Run dotnet new blazorwasm -n BlazorDashboardApp --hosted command.
配置服務器部分
1. 安裝以下NuGet軟件包:
DevExpress.AspNetCore.Dashboard
Microsoft.AspNetCore.Mvc.NewtonsoftJson
2. 創建App_Data / Dashboards文件夾來存儲儀表板。
3. 打開Startup.cs文件,并按如下所示更新ConfigureServices方法:
cs
using DevExpress.AspNetCore; using DevExpress.DashboardAspNetCore; using DevExpress.DashboardCommon; using DevExpress.DashboardWeb; using DevExpress.DataAccess.Json; using Microsoft.Extensions.FileProviders; using System; // ... public Startup(IConfiguration configuration, IWebHostEnvironment hostingEnvironment) { Configuration = configuration; FileProvider = hostingEnvironment.ContentRootFileProvider; } public IConfiguration Configuration { get; } public IFileProvider FileProvider { get; } public void ConfigureServices(IServiceCollection services) { services.AddResponseCompression(opts => { opts.MimeTypes = ResponseCompressionDefaults.MimeTypes.Concat( new[] { "application/octet-stream" }); }); services.AddDevExpressControls(); services.AddMvc() .AddDefaultDashboardController(configurator => { // Register Dashboard Storage configurator.SetDashboardStorage(new DashboardFileStorage(FileProvider.GetFileInfo("App_Data/Dashboards").PhysicalPath)); // Create a sample JSON data source DataSourceInMemoryStorage dataSourceStorage = new DataSourceInMemoryStorage(); DashboardJsonDataSource jsonDataSourceUrl = new DashboardJsonDataSource("JSON Data Source (URL)"); jsonDataSourceUrl.JsonSource = new UriJsonSource( new Uri("https://raw.githubusercontent.com/DevExpress-Examples/DataSources/master/JSON/customers.json")); jsonDataSourceUrl.RootElement = "Customers"; jsonDataSourceUrl.Fill(); dataSourceStorage.RegisterDataSource("jsonDataSourceUrl", jsonDataSourceUrl.SaveToXml()); configurator.SetDataSourceStorage(dataSourceStorage); }); services.AddControllersWithViews(); services.AddRazorPages(); }
4. 在同一文件中,按以下順序將app.UseDevExpressControls() 和 EndpointRouteBuilderExtension.MapDashboardRoute()方法調用添加到Configure方法中:
cs
// ... public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { // ... app.UseStaticFiles(); app.UseDevExpressControls(); app.UseRouting(); app.UseEndpoints(endpoints => { EndpointRouteBuilderExtension.MapDashboardRoute(endpoints, "api/dashboard"); // ... }); }
配置客戶端部分
1. 添加npm配置文件(package.json)并列出儀表板組件所需的以下npm軟件包:
json
{ "dependencies": { // ... "devexpress-dashboard": "~20.2.6" "@devexpress/analytics-core": "~20.2.6", "devextreme": "~20.2.6", "jquery-ui-dist": "1.12.1" }, // ... }
2. 右鍵單擊創建的package.json文件,然后選擇Restore Packages。
Alternative. Run npm install to install these packages.
3. 在Pages文件夾中,創建Dashboard Razor組件(Dashboard.razor),并添加以下代碼來呈現Web Dashboard:
razor
@page "/dashboard" @inject IJSRuntime JSRuntime @implements IDisposable <div id="web-dashboard" > </div> @code { protected override void OnAfterRender(bool firstRender) { JSRuntime.InvokeAsync<object>("JsFunctions.InitWebDashboard"); } public void Dispose() { JSRuntime.InvokeAsync<string>("JsFunctions.DisposeWebDashboard"); } }
注意:您應該調用儀表板組件的OnAfterRender方法進行初始化,并調用Dispose方法釋放未使用的內存。
4. 在wwwroot文件夾中,創建index.js文件,并實現初始化和處理組件的邏輯:
javascript
window.JsFunctions = { InitWebDashboard: function () { this.dashboardControl = new DevExpress.Dashboard.DashboardControl(document.getElementById("web-dashboard"), { endpoint: "/api/dashboard" }); this.dashboardControl.render(); }, DisposeWebDashboard: function () { this.dashboardControl.dispose(); } };
5. 安裝BuildBundlerMinifier NuGet軟件包,創建bundleconfig.json文件來捆綁Web儀表板所需的腳本和樣式:
javascript
[ { "outputFileName": "wwwroot/site/styles.css", "inputFiles": [ "node_modules/devextreme/dist/css/dx.light.css", "node_modules/@devexpress/analytics-core/dist/css/dx-analytics.common.css", "node_modules/@devexpress/analytics-core/dist/css/dx-analytics.light.css", "node_modules/@devexpress/analytics-core/dist/css/dx-querybuilder.css", "node_modules/devexpress-dashboard/dist/css/dx-dashboard.light.min.css" ], "minify": { "enabled": false, "adjustRelativePaths": false } }, { "outputFileName": "wwwroot/site/bundle.js", "inputFiles": [ "./index.js", "node_modules/jquery/dist/jquery.min.js", "node_modules/jquery-ui-dist/jquery-ui.min.js", "node_modules/knockout/build/output/knockout-latest.js", "node_modules/ace-builds/src-min-noconflict/ace.js", "node_modules/ace-builds/src-min-noconflict/ext-language_tools.js", "node_modules/ace-builds/src-min-noconflict/theme-dreamweaver.js", "node_modules/ace-builds/src-min-noconflict/theme-ambiance.js", "node_modules/devextreme/dist/js/dx.all.js", "node_modules/@devexpress/analytics-core/dist/js/dx-analytics-core.min.js", "node_modules/@devexpress/analytics-core/dist/js/dx-querybuilder.min.js", "node_modules/devexpress-dashboard/dist/js/dx-dashboard.min.js" ], "minify": { "enabled": false }, "sourceMap": false } ]
6. 在wwwroot文件夾中,打開index.html文件,并引用以下腳本和樣式表:
site/styles.css
site/bundle.js
index.js
.NET 5
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /> <title>BlazorDashboardApp</title> <base href="/" /> <link href="css/bootstrap/bootstrap.min.css" rel="stylesheet" /> <link href="css/app.css" rel="stylesheet" /> <link href="BlazorDashboardApp.Client.styles.css" rel="stylesheet" /> <link href="site/styles.css" rel="stylesheet" /> </head> <body> <div id="app">Loading...</div> <div id="blazor-error-ui"> An unhandled error has occurred. <a href="" class="reload">Reload</a> <a class="dismiss">????</a> </div> <script src="_framework/blazor.webassembly.js"></script> <script src="site/bundle.js"></script> <script src="index.js"></script> </body> </html>
.NET Core 3.1
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /> <title>BlazorDashboardApp</title> <base href="/" /> <link href="css/bootstrap/bootstrap.min.css" rel="stylesheet" /> <link href="css/app.css" rel="stylesheet" /> <link href="site/styles.css" rel="stylesheet" /> </head> <body> <app>Loading...</app> <div id="blazor-error-ui"> An unhandled error has occurred. <a href="" class="reload">Reload</a> <a class="dismiss">????</a> </div> <script src="_framework/blazor.webassembly.js"></script> <script src="site/bundle.js"></script> <script src="index.js"></script> </body> </html>
7. 在Shared / NavMenu.razor文件中,向列表中添加一個新的NavLink組件,來在導航菜單中顯示Web Dashboard項:
razor
<div class="@NavMenuCssClass" @onclick="ToggleNavMenu"> <ul class="nav flex-column"> <!--...--> <li class="nav-item px-3"> <NavLink class="nav-link" href="dashboard"> <span class="oi oi-list-rich" aria-hidden="true"></span> Web Dashboard </NavLink> </li> </ul> </div>
運行項目來查看結果:
