Getting Started with Blazor In-place Editor Component

10 Feb 202324 minutes to read

This section briefly explains about how to include Blazor In-place Editor component in your Blazor Server App and Blazor WebAssembly App using Visual Studio.

Prerequisites

• System requirements for Blazor components

Create a new Blazor App in Visual Studio

You can create Blazor Server App or Blazor WebAssembly App using Visual Studio in one of the following ways,

• Create a Project using Microsoft Templates

• Create a Project using Syncfusion Blazor Extension

Install Syncfusion Blazor InPlaceEditor NuGet in the App

Syncfusion Blazor components are available in nuget.org. To use Syncfusion Blazor components in the application, add reference to the corresponding NuGet. Refer to NuGet packages topic for available NuGet packages list with component details and Benefits of using individual NuGet packages.

To add 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), search for Syncfusion.Blazor.InPlaceEditor and then install it.

Register Syncfusion Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor namespace.

~/_Imports.razor

@using Syncfusion.Blazor

Now, register the Syncfusion Blazor Service in the Blazor Server App or Blazor WebAssembly App. Here, Syncfusion Blazor Service is registered by setting IgnoreScriptIsolation property as true to load the scripts externally in the next steps.

NOTE

From 2022 Vol-1 (20.1) version, the default value of IgnoreScriptIsolation is changed to true. It is not necessary to set the IgnoreScriptIsolation property to refer scripts externally, since the default value has already been changed to true, and this property is obsolete.

Blazor Server App

• For .NET 6 and .NET 7 app, open the ~/Program.cs file and register the Syncfusion Blazor Service.

• For .NET 5 and .NET 3.X app, open the ~/Startup.cs file and register the Syncfusion Blazor Service.

.NET 6 & .NET 7 (~/Program.cs)

using Microsoft.AspNetCore.Components;
using Microsoft.AspNetCore.Components.Web;
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorPages();
builder.Services.AddServerSideBlazor();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....

.NET 5 and .NET 3.X (~/Startup.cs)

using Syncfusion.Blazor;

namespace BlazorApplication
{
    public class Startup
    {
        ...
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddRazorPages();
            services.AddServerSideBlazor();
            services.AddSyncfusionBlazor();
        }
        ...
    }
}

Blazor WebAssembly App

Open ~/Program.cs file and register the Syncfusion Blazor Service in the client web app.

.NET 6 & .NET 7 (~/Program.cs)

using Microsoft.AspNetCore.Components.Web;
using Microsoft.AspNetCore.Components.WebAssembly.Hosting;
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.RootComponents.Add<App>("#app");
builder.RootComponents.Add<HeadOutlet>("head::after");

builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });

builder.Services.AddSyncfusionBlazor();
await builder.Build().RunAsync();
....

.NET 5 & .NET 3.X (~/Program.cs)

using Syncfusion.Blazor;

namespace WebApplication1
{
    public class Program
    {
        public static async Task Main(string[] args)
        {
            ....
            builder.Services.AddSyncfusionBlazor();
            await builder.Build().RunAsync();
        }
    }
}

Add style sheet

Checkout the Blazor Themes topic to learn different ways (Static Web Assets, CDN and CRG) to refer themes in Blazor application, and to have the expected appearance for Syncfusion Blazor components. Here, the theme is referred using Static Web Assets. Refer to Enable static web assets usage topic to use static assets in your project.

To add theme to the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for Syncfusion.Blazor.Themes and then install it. Then, the theme style sheet from NuGet can be referred as follows,

NOTE

If you are using Syncfusion.Blazor single NuGet, you don’t have to refer Syncfusion.Blazor.Themes NuGet. Since style sheets already inside the assets of Syncfusion.Blazor NuGet.

Blazor Server App

• For .NET 6 app, add the Syncfusion bootstrap5 theme in the <head> of the ~/Pages/_Layout.cshtml file.

• For .NET 3.X, .NET 5 and .NET 7 app, add the Syncfusion bootstrap5 theme in the <head> of the ~/Pages/_Host.cshtml file.

.NET 6 (~/_Layout.cshtml)

<head>
    ...
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <!--Refer theme style sheet as below if you are using Syncfusion.Blazor Single NuGet-->
    <!--<link href="_content/Syncfusion.Blazor/styles/bootstrap5.css" rel="stylesheet" />-->
</head>

.NET 3.X, .NET 5 & .NET 7 (~/_Host.cshtml)

<head>
    ...
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <!--Refer theme style sheet as below if you are using Syncfusion.Blazor Single NuGet-->
    <!--<link href="_content/Syncfusion.Blazor/styles/bootstrap5.css" rel="stylesheet" />-->
</head>

Blazor WebAssembly App

For Blazor WebAssembly App, Refer the theme style sheet from NuGet in the <head> of wwwroot/index.html file in the client web app.

~/index.html

<head>
    ...
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <!--Refer theme style sheet as below if you are using Syncfusion.Blazor Single NuGet-->
    <!--<link href="_content/Syncfusion.Blazor/styles/bootstrap5.css" rel="stylesheet" />-->
</head>

Add script reference

Checkout Adding Script Reference topic to learn different ways to add script reference in Blazor Application. In this getting started walk-through, the required scripts are referred using Static Web Assets externally inside the <head> as follows. Refer to Enable static web assets usage topic to use static assets in your project.

Blazor Server App

• For .NET 6 app, refer script in the <head> of the ~/Pages/_Layout.cshtml file.

• For .NET 3.X, .NET 5 and .NET 7 app, refer script in the <head> of the ~/Pages/_Host.cshtml file.

.NET 6 (~/_Layout.cshtml)

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
    <!--<script  src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js"  type="text/javascript"></script>-->
</head>

.NET 3.X, .NET 5 & .NET 7 (~/_Host.cshtml)

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
    <!--<script  src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js"  type="text/javascript"></script>-->
</head>

Blazor WebAssembly App

For Blazor WebAssembly App, refer script in the <head> of the ~/index.html file.

~/index.html

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
    <!--Use below script reference if you are using Syncfusion.Blazor Single NuGet-->
    <!--<script  src="_content/Syncfusion.Blazor/scripts/syncfusion-blazor.min.js"  type="text/javascript"></script>-->
</head>

NOTE

Syncfusion recommends to reference scripts using Static Web Assets, CDN and CRG by disabling JavaScript isolation for better loading performance of the Blazor application.

Add Blazor In-Place Editor component

• Open ~/_Imports.razor file or any other page under the ~/Pages folder where the component is to be added and import the Syncfusion.Blazor.InPlaceEditor namespace.

~/Imports.razor

@using Syncfusion.Blazor
@using Syncfusion.Blazor.InPlaceEditor
@using Syncfusion.Blazor.Inputs

• Now, add the Syncfusion In-place Editor component in razor file. Here, the In-place Editor component is added in the ~/Pages/Index.razor file under the ~/Pages folder.

CSHTML

<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

The type of component editor must be configured in the ‘Type’ Editor In-place property. Also, the two-way binding between the In-place Editor and its EditorComponent should be configured. It’s used to update the editor component value into the In-place Editor component.

• Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to run the application. Then, the Syncfusion Blazor In-place Editor component will be rendered in the default web browser.

NOTE

Render In-place Editor with popup

The following code explains how to initialize a simple In-place Editor with popup in the Blazor page.

CSHTML

@using Syncfusion.Blazor.InPlaceEditor
@using Syncfusion.Blazor.DropDowns

<table>
    <tr>
        <td>
            <label class="control-label">
                Choose a Country:
            </label>
        </td>
        <td>
            <SfInPlaceEditor Type="Syncfusion.Blazor.InPlaceEditor.InputType.AutoComplete" @bind-Value="@AutoValue" Mode="RenderMode.Popup" TValue="string">
                <EditorComponent>
                    <SfAutoComplete TValue="string" TItem="Countries" @bind-Value="@AutoValue" Placeholder="e.g. Australia" DataSource="@LocalData">
                        <AutoCompleteFieldSettings Value="Name"></AutoCompleteFieldSettings>
                    </SfAutoComplete>
                </EditorComponent>
            </SfInPlaceEditor>
        </td>
    </tr>
</table>

@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

You can render the Blazor DropDownList by changing the Type property as DropDownList and configuring the DropDownList component inside the Editor component.

CSHTML

@using Syncfusion.Blazor.DropDowns
@using Syncfusion.Blazor.InPlaceEditor

<SfInPlaceEditor @bind-Value="@DropdownValue" Type="Syncfusion.Blazor.InPlaceEditor.InputType.DropDownList" TValue="string">
    <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= "Game5", Text= "Football" },
    new Games() { ID= "Game6", Text= "Golf" },
    new Games() { ID= "Game7", Text= "Hockey" },
    new Games() { ID= "Game8", Text= "Rugby"},
    new Games() { ID= "Game9", Text= "Snooker" },
    new Games() { ID= "Game10", Text= "Tennis"},
  };
}

Integrate DatePicker

You can render the Blazor DatePicker by changing the Type property as Date and configuring the DatePicker component inside the Editor component. Also, configure its properties directly in the Datepicker component.

CSHTML

@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.

CSHTML

@using Syncfusion.Blazor.InPlaceEditor
@using Syncfusion.Blazor.Inputs
@using Syncfusion.Blazor.Calendars
@using Syncfusion.Blazor.DropDowns

<div id="container" class="control-group">
    <h3> Modify Basic Details </h3>
    <table style="margin: 10px auto;">
        <tr>
            <td>Name</td>
            <td class='left'>
                <SfInPlaceEditor @bind-Value="@TextValue" TValue="string">
                    <EditorComponent>
                        <SfTextBox @bind-Value="@TextValue" Placeholder="Enter your name"></SfTextBox>
                    </EditorComponent>
                </SfInPlaceEditor>
            </td>
        </tr>
        <tr>
            <td>Date of Birth</td>
            <td class='left'>
                <SfInPlaceEditor Type="Syncfusion.Blazor.InPlaceEditor.InputType.Date" TValue="DateTime?" @bind-Value="@DateValue">
                    <EditorComponent>
                        <SfDatePicker TValue="DateTime?" @bind-Value="@DateValue" Placeholder="Select date"></SfDatePicker>
                    </EditorComponent>
                </SfInPlaceEditor>
            </td>
        </tr>
        <tr>
            <td>Gender</td>
            <td class='left'>
                <SfInPlaceEditor @bind-Value="@DropdownValue" Type="Syncfusion.Blazor.InPlaceEditor.InputType.DropDownList"  TValue="string">
                    <EditorComponent>
                        <SfDropDownList Width="90%" TItem="Gender" TValue="string" DataSource="@dropdownData" @bind-Value="@DropdownValue">
                            <DropDownListFieldSettings Text="text" Value="text"></DropDownListFieldSettings>
                        </SfDropDownList>
                    </EditorComponent>
                </SfInPlaceEditor>
            </td>
        </tr>
    </table>
</div>

<style>
    #container {
        text-align: center;
        margin-top: 50px;
    }

        #container table {
            width: 400px;
            margin: auto;
        }

            #container table td {
                height: 70px;
                width: 150px;
            }

            #container table .left {
                text-align: left;
            }
</style>

@code {
    public DateTime? DateValue { get; set; } = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);
    public string TextValue = "Andrew";
    public string DropdownValue = "Male";

    public class Gender
    {
        public string value { get; set; }
        public string text { get; set; }
    }
    List<Gender> dropdownData = new List<Gender>()
    {
        new Gender(){ text= "Male" },
        new Gender(){ text= "Female" }
    };
}

Submitting data to the server (save)

You can submit editor value to the server by configuring the SaveUrl, Adaptor and PrimaryKey properties.

Property	Usage
SaveUrl	Gets the URL for server submit action.
Adaptor	Specifies the adaptor type that is used by DataManager to communicate with DataSource.
PrimaryKey	Defines the unique primary key of editable field which can be used for saving data in the data-base.

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

Refresh In-place Editor with modified value

The edited data is submitted to the server and you can see the new values getting reflected in the In-place Editor.
