Licensed Users: If you own a subscription that was active when 21.1 was released, log into the DevExpress Download Manager. Use the version dropdown menu to select v21.1 and download the specific installer (e.g., .NET Productivity Tools, Reporting, or DevExtreme).
Trial Users: The official DevExpress trial usually provides the latest major version (e.g., v23.2 or v24.1). If you specifically need 21.1 for evaluation, you may need to contact DevExpress Support to request a legacy trial installer.
NuGet Packages: For .NET projects, you can manage specific version dependencies via the DevExpress NuGet Gallery. You will need your personal feed URL to restore packages for version 21.1.x. Key Features in DevExpress 21.1

When installing DevExpress 21.1, developers must ensure that the target Visual Studio version is supported. Version 21.1 supports Visual Studio 2019 and Visual Studio 2022. The installer integrates the toolbox items directly into the Visual Studio IDE and registers the design-time designers.
The Dashboard control now offers enhanced client-side customization. End-users can modify the layout and data visualization widgets at runtime, and these configurations can be saved and restored server-side.
If you are installing the design-time components (Visual Studio Toolbox, Report Designer, etc.), local admin rights are required.
Version 21.1 significantly expanded DevExpress's offering for Blazor, Microsoft's framework for building interactive web UIs with C#. This release introduced the Data Grid, Pivot Grid, and Chart components for Blazor, allowing developers to move away from JavaScript-heavy front ends and utilize C# for full-stack development.
