Getting Started with Blazor In-place Editor in Blazor Web App

9 Jul 202621 minutes to read

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

Create a new Blazor Web App

Create a Blazor Web App using Visual Studio via Microsoft Templates or the Blazor Extension.

Run the following command to create a new Blazor Web App.

Terminal

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

Alternatively, create a Blazor Web App using Visual Studio Code via Microsoft Templates, the Blazor Extension, or the C# Dev Kit extension.

Run the following command to create a new Blazor Web App.

Command Prompt

dotnet new blazor -o BlazorWebApp --interactivity Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Web App. For detailed information, refer to the interactive render mode documentation.

Install the required Blazor packages

Install the Syncfusion.Blazor.InPlaceEditor and Syncfusion.Blazor.Themes NuGet packages. All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details. If using the WebAssembly or Auto render modes in the Blazor Web App, install these packages in the .Client project.

Go to Tools → NuGet Package Manager → Manage NuGet Packages for Solution.
Search the required NuGet packages (Syncfusion.Blazor.InPlaceEditor and Syncfusion.Blazor.Themes) and install them.

Alternatively, you can install the same packages using the Package Manager Console with the following commands.

Package Manager Console

Install-Package Syncfusion.Blazor.InPlaceEditor -Version 34.1.29
Install-Package Syncfusion.Blazor.Themes -Version 34.1.29

Open the terminal and run the following commands.

Terminal

dotnet add package Syncfusion.Blazor.InPlaceEditor -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Open the command prompt and run the following commands.

Command Prompt

dotnet add package Syncfusion.Blazor.InPlaceEditor -v 34.1.29
dotnet add package Syncfusion.Blazor.Themes -v 34.1.29

Add import namespaces

After the packages are installed, open the ~/_Imports.razor file in the .Client project and import the Syncfusion.Blazor and Syncfusion.Blazor.InPlaceEditor namespaces.

~/_Imports.razor

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

Register the Blazor service

Open the Program.cs file in Blazor Web App and register the Blazor service. If the Interactive Render Mode is set to WebAssembly or Auto, register the Blazor service in Program.cs files of both the server and client projects in your Blazor Web App.

Program.cs
....
using Syncfusion.Blazor;
....
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 and script references in the App.razor file.

App.razor
...
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
...
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>

Add Blazor In-place Editor component

Open a Razor file located in the ~/Pages/*.razor (for example, Home.razor) and add the Blazor In-place Editor component inside the razor file.

NOTE

If the interactivity location is set to Per page/component in the Web App, define a render mode at the top of the razor file. (For example, InteractiveServer, InteractiveWebAssembly or InteractiveAuto). If the Interactivity is set to Global with Auto or WebAssembly, the render mode is automatically configured in the App.razor file by default.

Home.razor
@rendermode InteractiveAuto

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

<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.

Run the application

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

Open the terminal and navigate to the server project folder (for example, BlazorWebApp) then run the following command.

Terminal

cd ..
cd BlazorWebApp
dotnet run

Open the command prompt and navigate to the server project folder (for example, BlazorWebApp) then run the following command.

Command Prompt

cd ..
cd BlazorWebApp
dotnet run

NOTE

View Sample in GitHub.

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

Home.razor
@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="Syncfusion.Blazor.InPlaceEditor.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

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

Home.razor
@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

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.

Home.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.

Home.razor
@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" }
    };
}

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.

Home.razor
@using Syncfusion.Blazor.DropDowns
@using Syncfusion.Blazor.InPlaceEditor

<div id="container">
    <div class="control-group">
        Best Employee of the year:

        <SfInPlaceEditor @ref="InPlaceObj" PrimaryKey="Employee" Name="Employee" Adaptor="Adaptors.UrlAdaptor" SaveUrl="https://ej2services.syncfusion.com/production/web-services/api/Editor/UpdateData" Type="Syncfusion.Blazor.InPlaceEditor.InputType.DropDownList" @bind-Value="@DropdownValue" TValue="string">
