3 Dec 202524 minutes to read

This section briefly explains about how to include Blazor In-place Editor component in your Blazor Web App using Visual Studio, Visual Studio Code, and the .NET CLI.

Prerequisites

System requirements for Blazor components

Create a new Blazor Web App in Visual Studio

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion^® Blazor Extension.

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App.

Create Blazor Web App

Install Syncfusion^® Blazor InPlaceEditor and Themes NuGet in the Blazor Web App

To add the Blazor In-place Editor component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), then search and install Syncfusion.Blazor.InPlaceEditor and Syncfusion.Blazor.Themes.

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion^® Blazor component NuGet packages in the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Package Manager
Install-Package Syncfusion.Blazor.InPlaceEditor -Version 31.2.12
Install-Package Syncfusion.Blazor.Themes -Version 31.2.12

NOTE

Syncfusion^® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Prerequisites

System requirements for Blazor components

Create a new Blazor Web App in Visual Studio Code

You can create a Blazor Web App using Visual Studio Code via Microsoft Templates or the Syncfusion^® Blazor Extension.

Configure the appropriate interactive render mode and interactivity location when setting up a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands.

Blazor Web App
dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Install Syncfusion^® Blazor InPlaceEditor and Themes NuGet in the App

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion^® Blazor component NuGet packages in the client project.

Press Ctrl+` to open the integrated terminal in Visual Studio Code.
Ensure you’re in the project root directory where your .csproj file is located.
Run the following command to install a Syncfusion.Blazor.InPlaceEditor and Syncfusion.Blazor.Themes NuGet package and ensure all dependencies are installed.

Package Manager
dotnet add package Syncfusion.Blazor.InPlaceEditor -v 31.2.12
dotnet add package Syncfusion.Blazor.Themes -v 31.2.12
dotnet restore

NOTE

Syncfusion^® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Prerequisites

Latest version of the .NET SDK. If you previously installed the SDK, you can determine the installed version by executing the following command in a command prompt (Windows) or terminal (macOS) or command shell (Linux).

.NET CLI
dotnet --version

Create a Blazor Web App using .NET CLI

Run the following command to create a new Blazor Web App in a command prompt (Windows) or terminal (macOS) or command shell (Linux). For detailed instructions, refer to this Blazor Web App Getting Started documentation.

Configure the appropriate interactive render mode and interactivity location when setting up a Blazor Web Application. For detailed information, refer to the interactive render mode documentation.

For example, in a Blazor Web App with Auto interactive render mode, use the following commands:

.NET CLI
dotnet new blazor -o BlazorApp -int Auto
cd BlazorApp
cd BlazorApp.Client

This command creates a new Blazor Web App and places it in a new directory called BlazorApp inside your current location. See the Create a Blazor App and dotnet new CLI command topics for more details.

Install Syncfusion^® Blazor InPlaceEditor and Themes NuGet in the App

Here’s an example of how to add Blazor In-place Editor component in the application using the following command in the command prompt (Windows) or terminal (Linux and macOS) to install a Syncfusion.Blazor.InPlaceEditor and Syncfusion.Blazor.Themes NuGet package. See Install and manage packages using the dotnet CLI topics for more details.

If using the WebAssembly or Auto render modes in the Blazor Web App, install Syncfusion^® Blazor component NuGet packages in the client project.

.NET CLI
dotnet add package Syncfusion.Blazor.InPlaceEditor --version 31.2.12
dotnet add package Syncfusion.Blazor.Themes --version 31.2.12
dotnet restore

NOTE

Syncfusion^® Blazor components are available in nuget.org. Refer to the NuGet packages topic for the available NuGet packages list with component details.

Add Import Namespaces

Open the ~/_Imports.razor file from the client project and import the Syncfusion.Blazor and Syncfusion.Blazor.InPlaceEditor namespace.

~/_Imports.razor
@using Syncfusion.Blazor
@using Syncfusion.Blazor.InPlaceEditor

Register Syncfusion^® Blazor Service

If the Interactive Render Mode is set to WebAssembly or Auto, register the Syncfusion^® Blazor service in the ~/Program.cs files of the main server project and associated .Client project.

Server(~/_Program.cs)
Client(~/_Program.cs)
...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();

await builder.Build().RunAsync();

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.Core/scripts/syncfusion-blazor.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 In-place Editor component

Add the Syncfusion^® Blazor In-place Editor component to a Razor page located under the Pages folder (e.g., Pages/Home.razor) in either the Server or Client project. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:

Interactivity location	RenderMode	Code
Per page/component	Auto	@rendermode InteractiveAuto
	WebAssembly	@rendermode InteractiveWebAssembly
	None	—

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Auto or WebAssembly, the render mode is configured in the App.razor file by default.

<table>
    <tr>
        <td>
            <label class="control-label" style="text-align: left;font-size: 14px;font-weight: 400">
                TextBox
            </label>
        </td>
        <td>
            <SfInPlaceEditor @bind-Value="@TextValue" TValue="string">
                <EditorComponent>
                    <SfTextBox @bind-Value="@TextValue" Placeholder="Enter employee name"></SfTextBox>
                </EditorComponent>
            </SfInPlaceEditor>
        </td>
    </tr>
</table>

@code {
    public string TextValue = "Andrew";
}

NOTE

Specify the editor Type when using non-default editors (for example, DropDownList, Date, or AutoComplete). Configure two-way binding between the In-place Editor and its editor component to synchronize values.

Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion^® Blazor In-place Editor component in the default web browser.

@code {
    public string AutoValue = "Australia";

    public class Countries
    {
        public string Name { get; set; }
        public string Code { get; set; }
    }

    List<Countries> LocalData = new List<Countries> {
        new Countries() { Name = "Australia", Code = "AU" },
        new Countries() { Name = "Bermuda", Code = "BM" },
        new Countries() { Name = "Canada", Code = "CA" },
        new Countries() { Name = "Cameroon", Code = "CM" },
        new Countries() { Name = "Denmark", Code = "DK" }
    };
}

Configuring DropDownList

Render the Blazor DropDownList by changing the Type property to DropDownList and configuring the DropDownList component inside the editor component.

    <EditorComponent>
        <SfDropDownList TValue="string" TItem="Games"  @bind-Value="@DropdownValue" Placeholder="Select a game" DataSource="@LocalData">
            <DropDownListFieldSettings Value="ID" Text="Text"></DropDownListFieldSettings>
        </SfDropDownList>
    </EditorComponent>
</SfInPlaceEditor>

@code {
    public string DropdownValue = "Game4";

    public class Games
    {
        public string ID { get; set; }
        public string Text { get; set; }
    }
    List<Games> LocalData = new List<Games> {
    new Games() { ID= "Game1", Text= "American Football" },
    new Games() { ID= "Game2", Text= "Badminton" },
    new Games() { ID= "Game3", Text= "Basketball" },
    new Games() { ID= "Game4", Text= "Cricket" },

    new Games() { ID= "Game9", Text= "Snooker" },
    new Games() { ID= "Game10", Text= "Tennis"},
  };
}

Integrate DatePicker

Render the Blazor DatePicker by changing the Type property to Date and configuring the DatePicker component inside the editor component. Also configure its properties directly on the DatePicker component.

RAZOR
@using Syncfusion.Blazor.InPlaceEditor
@using Syncfusion.Blazor.Calendars

<SfInPlaceEditor Type="Syncfusion.Blazor.InPlaceEditor.InputType.Date" TValue="DateTime?" @bind-Value="@DateValue">
    <EditorComponent>
        <SfDatePicker TValue="DateTime?" @bind-Value="@DateValue" Placeholder="Choose a Date"></SfDatePicker>
    </EditorComponent>
</SfInPlaceEditor>

@code {
    public DateTime? DateValue { get; set; } = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);

}

In the following code, it is configured to render the DatePicker, DropDownList and Textbox components.

Integrating DatePicker in Blazor In-place Editor

Submitting data to the server (save)

Submit the editor value to the server by configuring the SaveUrl, Adaptor, and PrimaryKey properties.

Property	Usage
`SaveUrl`	Gets the URL for the server submit action.
`Adaptor`	Specifies the adaptor type used by DataManager to communicate with the data source.
`PrimaryKey`	Defines the unique primary key of the editable field used for saving data in the database.

The PrimaryKey property is mandatory. If it is not set, edited data are not sent to the server.

Refresh Blazor In-place Editor with modified value

After submit, the edited data is sent to the server, and the updated value is reflected in the In-place Editor.
