23 Jul 20263 minutes to read

This section briefly explains how to include the ASP.NET Core Image Editor control in your ASP.NET Core application using Visual Studio.

Create an ASP.NET Core Web App with Razor pages

Create an ASP.NET Core Web App using Visual Studio via Microsoft Templates or the ASP.NET Core Extension. For detailed instructions, refer to the ASP.NET Core Web App Getting Started documentation.

Install the required ASP.NET Core packages

To add ASP.NET Core Image Editor control in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search for and install the Syncfusion.AspNetCore.ImageEditor and Syncfusion.AspNetCore.Themes packages. All Syncfusion ASP.NET Core packages are available on nuget.org. See the NuGet packages topic for details.

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

Install-Package Syncfusion.AspNetCore.ImageEditor -Version 34.1.29
Install-Package Syncfusion.AspNetCore.Themes -Version 34.1.29

Add ASP.NET Core Tag Helpers

After the packages are installed, open the ~/Pages/_ViewImports.cshtml file and import the Syncfusion.AspNetCore.Base and Syncfusion.AspNetCore.ImageEditor Tag Helpers.

@addTagHelper *, Syncfusion.AspNetCore.Base
@addTagHelper *, Syncfusion.AspNetCore.ImageEditor

Add stylesheet and script resources

The theme stylesheet and script can be referenced from CDN. Include the stylesheet and script references inside the <head> of ~/Pages/Shared/_Layout.cshtml.

<head>
    ...
    @* ASP.NET Core controls styles *@
    <link rel="stylesheet" href="_content/Syncfusion.AspNetCore.Themes/styles/fluent2.css" />
    @* ASP.NET Core controls scripts *@
     <script src="_content/Syncfusion.AspNetCore.ImageEditor/scripts/sf-image-editor.min.js"></script>
</head>

Register the Script Manager

Open the ~/Pages/Shared/_Layout.cshtml file and register the script manager <ejs-scripts> at the end of the <body> element as follows.

<body>
    ...
    @*  ASP.NET Core Script Manager *@
    <ejs-scripts></ejs-scripts>
</body>

Add ASP.NET Core Image Editor Control

Add the ASP.NET Core Image Editor control in the ~/Pages/Index.cshtml file.

<div class="col-lg-12 control-section e-img-editor-sample">
    <ejs-imageeditor id="image-editor"></ejs-imageeditor>
</div>

<style>
    .image-editor {
        margin: 0 auto;
    }

    .e-img-editor-sample {
        height: 80vh;
        width: 100%;
    }

    @@media only screen and (max-width: 700px) {
        .e-img-editor-sample {
            height: 75vh;
            width: 100%;
        }
    }

    .control-wrapper {
        height: 100%;
    }
</style>
