Getting started with Blazor In-place Editor component

22 Jul 2021 / 7 minutes to read

This section briefly explains how to include a In-Place Editor component in your Blazor Server-side application. You can refer to our 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.InPlaceEditor NuGet package to the application by using the NuGet Package Manager.
You can add the client-side resources through CDN or from NuGet package in the HEAD element of the ~/Pages/_Host.cshtml page.

<head>
<environment include="Development">
....
....
    <link href="_content/Syncfusion.Blazor/styles/fabric.css" rel="stylesheet" />
    <!---CDN--->
    @*<link href="https://cdn.syncfusion.com/blazor/18.4.42/styles/fabric.css" rel="stylesheet" />*@
   </environment>
</head>

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

<head>
   <environment include="Development">
  <link href="_content/Syncfusion.Blazor/styles/fabric.css" rel="stylesheet" />
  <script src="https://github.com/Daddoon/Blazor.Polyfill/releases/download/3.0.1/blazor.polyfill.min.js"></script>
  </environment>
</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();
    }
}
}

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 with TextBox in the Razor page.

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

<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";
}

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

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" }
};
}

Run the application

After successful compilation of your application, run the application.

Output be like the below.

Inplace-editor inline mode

Inplace-editor popup mode

Configuring DropDownList

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

The following sample demonstrates how to render the DropDownList component in the In-place Editor,

@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 = "Cricket";

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 configure DatePicker component inside the Editor component. Also, configure its properties directly in the Datepicker component

The following sample demonstrates how to render the DatePicker component in the In-place Editor,

@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>
            </SfInPlaceEditor>
        </td>
    </tr>
    <tr>
        <td>Gender</td>
        <td class='left'>
            <SfInPlaceEditor @bind-Value="@DropdownValue" Type="Syncfusion.Blazor.InPlaceEditor.InputType.DropDownList"  TValue="string">

                    <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" }
};
}

Output be like the below.

Inplace-editor components

Submitting data to the server (save)

You can submit editor value to the server by configuring the SaveUrl, 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.DropDowns
@using Syncfusion.Blazor.InPlaceEditor
