Getting started with Blazor InPlaceEditor component

This section briefly explains how to include a In-Place Editor component in your Blazor Server-side application. You can refer Getting Started with Syncfusion Blazor for Server-Side in Visual Studio 2019 page for the introduction and configuring the common specifications.

Importing Syncfusion Blazor component in the application

Install Syncfusion.Blazor NuGet package to the application by using the NuGet Package Manager.

Please ensure to check the Include prerelease option for our Beta release.

You can add the client-side resources through CDN or from NuGet package in the <head> element of the ~/Pages/_Host.cshtml page.

<head>
    <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
    @*<link href="https://cdn.syncfusion.com/blazor/18.1.53/styles/bootstrap4.css" rel="stylesheet" />*@
</head>

For Internet Explorer 11 kindly refer the polyfills. Refer the documentation for more information.

<head>
    <link href="_content/Syncfusion.Blazor/styles/bootstrap4.css" rel="stylesheet" />
    <script src="https://github.com/Daddoon/Blazor.Polyfill/releases/download/3.0.1/blazor.polyfill.min.js"></script>
</head>

Adding component package to the application

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

@using Syncfusion.Blazor.InPlaceEditor

Add SyncfusionBlazor service in Startup.cs

Open the Startup.cs file and add services required by Syncfusion components using services.AddSyncfusionBlazor() method. Add this method in the ConfigureServices function as follows.

using Syncfusion.Blazor;
namespace BlazorApplication
{
    public class Startup
    {
        ....
        ....
        public void ConfigureServices(IServiceCollection services)
        {
            ....
            ....
            services.AddSyncfusionBlazor();
        }
    }
}

To enable custom client side resource loading from CRG or CDN. You need to disable resource loading by AddSyncfusionBlazor(true) and load the scripts in the <head> element of the ~/Pages/_Host.cshtml page.

<head>
    <script src="https://cdn.syncfusion.com/blazor/18.1.53/syncfusion-blazor.min.js"></script>
</head>

Add In-Place Editor component

To initialize the In-Place Editor component, add the below code to your Index.razor view page which is present under ~/Pages folder.

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

@using Syncfusion.Blazor
@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 Mode="RenderMode.Inline" Type="InputType.Text" Value="@TextValue" SubmitOnEnter="true" Model="@TModel">
            </SfInPlaceEditor>
        </td>
    </tr>
</table>

@code {
    public string TextValue = "Andrew";

    public TextBoxModel TModel = new TextBoxModel()
    {
        Placeholder = "Enter employee name"
    };
}

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

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

<table>
    <tr>
        <td>
            <label class="control-label">
                Choose a Country:
            </label>
        </td>
        <td>
            <SfInPlaceEditor Mode="RenderMode.Popup" Type="InputType.AutoComplete" Value="@AutoValue" Model="@AutocompleteData">
            </SfInPlaceEditor>
        </td>
    </tr>
</table>

@code {
    public string AutoValue = "Australia";

    public AutoCompleteModel<string> AutocompleteData = new AutoCompleteModel<string>()
    {
        Placeholder = "Type to search countries",
        DataSource = new string[] { "Australia", "Bermuda", "Canada", "Cameroon", "Denmark", "Finland", "Greenland", "Poland" }
    };
}

Run the application

After successful compilation of your application, run the application.

Output be like the below.

Configuring DropDownList

You can render the Blazor DropDownList by changing the Type property as DropDownList and configure its properties and methods using the Model property.

In the following example, Type and model values are configured to render the DropDownList component.

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

<SfInPlaceEditor Mode="RenderMode.Inline" Type="InputType.DropDownList" Value="@DropdownValue" Model="@DropdownData" />

@code {
    public string DropdownValue = "Australia";

    public DropDownListModel<string> DropdownData = new DropDownListModel<string>()
    {
        Placeholder = "Select Country",
        DataSource = new string[] { "Australia", "Bermuda", "Canada", "Cameroon", "Denmark", "Finland", "Greenland", "Poland" }
    };
}

Integrate DatePicker

You can render the Blazor DatePicker by changing the Type property as Date and also configure its properties and methods using the Model property.

In the following sample, Type and Model values are configured to render the DatePicker component.

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

<SfInPlaceEditor Mode="RenderMode.Inline" Type="InputType.Date" Value="@DateValue" Model="@DateModel" />

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

    public DatePickerModel DateModel = new DatePickerModel()
    {
        Placeholder = "Select date",
        ShowTodayButton = true
    };
}

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

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

<div id="container" class="control-group">

    <table style="margin: 10px auto;">
        <tr>
            <td>Name</td>
            <td class='left'>
                <SfInPlaceEditor Mode="RenderMode.Inline" Type="InputType.Text" Value="@TextValue" Model="@TModel">
                </SfInPlaceEditor>
            </td>
        </tr>
        <tr>

Inplace-editor components

Submitting data to the server (save)

You can submit editor value to the server by configuring the Url, Adaptor and PrimaryKey property.

Property	Usage
`Url`	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.

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