Getting Started with Blazor DocumentEditor Component in Web App
29 Nov 20245 minutes to read
This section briefly explains about how to include Blazor DocumentEditor component in your Blazor Web App using Visual Studio.
Prerequisites
Create a new Blazor Web App
You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.
You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.
Install Syncfusion® Blazor WordProcessor and Themes NuGet in the Blazor Web App
To add Blazor DocumentEditor component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.WordProcessor and Syncfusion.Blazor.Themes.
If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.
Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.WordProcessor -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33NOTE
Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.
Register Syncfusion® Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.DocumentEditor namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.DocumentEditorNow, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App. For a app with WebAssembly or Auto (Server and WebAssembly) interactive render mode, register the Syncfusion® Blazor service in both ~/Program.cs files of your web app.
....
using Syncfusion.Blazor;
....
builder.Services.AddServerSideBlazor().AddHubOptions(o => { o.MaximumReceiveMessageSize = 102400000; });
....
builder.Services.AddSyncfusionBlazor();
....Add stylesheet and script resources
The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
....
<body>
....
<script src="_content/Syncfusion.Blazor.WordProcessor/scripts/syncfusion-blazor-documenteditor.min.js" type="text/javascript"></script>
</body>NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.
Add Syncfusion® Blazor DocumentEditor component
Add the Syncfusion® Blazor DocumentEditor component in .razor file inside the Pages folder. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:
@* desired render mode define here *@
@rendermode InteractiveAutoNOTE
Supported render mode are
@rendermode InteractiveAuto,@rendermode InteractiveServer,@rendermode InteractiveWebAssembly. If an interactivity location as Global no need to mention render mode. Set the interactivity mode for whole sample. Check out the Blazor Render Modes for other Render Modes.
<SfDocumentEditorContainer EnableToolbar=true></SfDocumentEditorContainer>Note: By default, the SfDocumentEditorContainer component initializes a SfDocumentEditor instance internally. If you like to use the events of SfDocumentEditor component, then you can set UseDefaultEditor property as false and define your own SfDocumentEditor instance with event hooks in the application (Razor file).
- Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor DocumentEditor component in your default web browser.
Load existing document
To load an existing document during control initialization, use the following code example, which opens a Word document. Convert it to SFDT and load in the editor.
@using System.IO;
@using Syncfusion.Blazor.DocumentEditor;
<SfDocumentEditorContainer @ref="container" EnableToolbar=true>
<DocumentEditorContainerEvents Created="OnCreated"></DocumentEditorContainerEvents>
</SfDocumentEditorContainer>
@code {
SfDocumentEditorContainer container;
public void OnCreated(object args)
{
string filePath = "wwwroot/data/GettingStarted.docx";
using (FileStream fileStream = new FileStream(filePath, System.IO.FileMode.Open, System.IO.FileAccess.Read))
{
WordDocument document = WordDocument.Load(fileStream, ImportFormatType.Docx);
string json = JsonSerializer.Serialize(document);
document.Dispose();
//To observe the memory go down, null out the reference of document variable.
document = null;
SfDocumentEditor editor = container.DocumentEditor;
editor.OpenAsync(json);
//To observe the memory go down, null out the reference of json variable.
json = null;
}
}
}NOTE
As per the discussion thread #30064, null out the reference of streams and other instances when they are no longer required. Using this approach you’ll observe the memory go down and become stable.
NOTE
