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

16 Feb 202418 minutes to read

This section briefly explains about how to include Blazor In-place Editor 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 InPlaceEditor and Themes NuGet in the Blazor Web App

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 and install Syncfusion.Blazor.InPlaceEditor 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.InPlaceEditor -Version 25.1.35
Install-Package Syncfusion.Blazor.Themes -Version 25.1.35

NOTE

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.InPlaceEditor namespace.

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

Now, 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.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.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 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 InteractiveAuto
<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 launch the application. This will render the Syncfusion Blazor In-place Editor component in your default web browser.

Render Blazor In-place Editor with popup

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

@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.

@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.

@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.

@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)

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 Blazor 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.
