This project demonstrates the Preview (CTP) version of DevExpress UI Components for Blazor.
The DevExpress UI components featured in this demo are available for free download and can be used in your next Blazor app.*
* Like any software preview, the DevExpress UI for Blazor is not without fault. You should not use these products in production environments or in mission-critical applications.

- Install the latest Visual Studio 2019 update.
- Ensure that you have the latest .NET Core 3 version (from supported versions listed above) installed.
- If you use the release version of Visual Studio 2019, ensure the "Use previews of the .NET Core SDK" option is enabled.
The corresponding check box's location depends on the Visual Studio build number. You can find the check box here:
or here:
The Blazor framework uses either WebAssembly-based .NET runtime (client-side Blazor) or server-side ASP.NET Core (server-side Blazor). Our Blazor components support both of these approaches.
You can find appropriate demos in the repositories below:
- demo/BlazorDemo.ServerSide
- demo/BlazorDemo.ClientSide
- demo/BlazorDemo.ClientSideWithPrerendering*
* For more information, see the Update Metadata at Runtime - Free SEO Tool blog post.

Follow the steps below to try our UI for Blazor in your own application.
- Create a new solution using the "Blazor (server-side)" or "Blazor" template in Visual Studio 2019.
In the "Create a new project" dialog select "Blazor App".
In the next step select the "Blazor (server-side)" project template.
- Register the DevExpress Early Access feed in Visual Studio's NuGet Package Manager.
Open the "Package Manager Settings".
Add new NuGet source:
https://nuget.devexpress.com/early-access/api
-
Install the "DevExpress.Blazor" NuGet package.
Navigate to:
Select the "Early Access" NuGet package source you have just created in the "Package source" combo box.
Install the "DevExpress.Blazor" NuGet package.
-
Build the project.
-
Make sure the following folder is automatically created in your project’s
wwwrootdirectory:Lib/dx-blazor dx-blazor/.gitignore dx-blazor/modules/ dx-blazor/dx-blazor.js dx-blazor/dx-blazor.cssFor existing Blazor projects, copy the DevExpress static files from the
Lib/dx-blazorfolder to the appropriate folder in your project.The
Lib/dx-blazorfolder is automatically cleared while the project is built and contains static files for an installed nuget package only. Do not store your files here. -
Link the
dx-blazor.jsanddx-blazor.cssfiles to your layout’s HEAD section:- For server-side Blazor, add the lines below to the _Host.cshtml file.
- For client-side Blazor, add the lines below to the Index.cshtml file.
<head> ... <link href="lib/dx-blazor/dx-blazor.css" rel="stylesheet" /> <script src="lib/dx-blazor/dx-blazor.js"></script> </head>
Reference this JavaScript file only because the
dx-blazor/dx-blazor.jsfile is the entry point for DevExpress module files. -
Register DevExpress.Blazor namespace in _Imports.razor file:
@using DevExpress.Blazor
-
Your application is ready to use DevExpress Blazor.
If you use Blazor (client-side) with DxDataGrid, you may see the following exception in a browser:
"System.InvalidOperationException: No generic method 'Take' on type 'System.Linq.Queryable' is compatible with the supplied type arguments and arguments."
The solution is to follow the official Blazor documentation.
So, you can either Disable linking or Control linking.
In case you decide to control linking: the following types types must be added in the Linker.xml file:
<type fullname="System.Linq.Expressions*" />
<type fullname="System.Linq.Queryable*" />
<type fullname="System.Linq.Enumerable*" />
<type fullname="System.Linq.EnumerableRewriter*" />
So, the Linker.xml file should look as follows:
<?xml version="1.0" encoding="UTF-8" ?>
...
<linker>
<assembly fullname="mscorlib">
...
<type fullname="System.Threading.WasmRuntime" />
</assembly>
<assembly fullname="System.Core">
...
<type fullname="System.Linq.Expressions*" />
<type fullname="System.Linq.Queryable*" />
<type fullname="System.Linq.Enumerable*" />
<type fullname="System.Linq.EnumerableRewriter*" />
</assembly>
...
<assembly fullname="[PUT YOUR ASSEMBLY NAME HERE]" />
</linker>
