Getting Started with Blazor Dashboard Layout Component in Server App
18 Nov 201822 minutes to read
This section briefly explains about how to include Blazor Dashboard Layout component in a Blazor Server App using Visual Studio, Visual Studio Code, and the .NET CLI.
Prerequisites
Create a new Blazor App in Visual Studio
Create a Blazor Server App by using the Blazor Web App template in Visual Studio via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor Server App Getting Started documentation.
Prerequisites
Create a new Blazor App in Visual Studio Code
Create a Blazor Server App using Visual Studio Code via Microsoft Templates or the Syncfusion® Blazor Extension. For detailed instructions, refer to the Blazor Server App Getting Started documentation.
Alternatively, create a Server application by using the following command in the integrated terminal (Ctrl+`).
dotnet new blazor -o BlazorApp -int Server
cd BlazorAppPrerequisites
Install the latest version of .NET SDK. If the .NET SDK is already installed, determine the installed version by running the following command in a command prompt (Windows), terminal (macOS), or command shell (Linux).
dotnet --versionCreate a Blazor Server App using .NET CLI
Run the following command to create a new Blazor Server App in a command prompt (Windows) or terminal (macOS) or command shell (Linux). For detailed instructions, refer to the Blazor Server App Getting Started documentation.
dotnet new blazor -o BlazorApp -int Server
cd BlazorAppNOTE
Configure the appropriate Interactive render mode and Interactivity location while creating a Blazor Server App. For detailed information, refer to the interactive render mode documentation.
Install required Blazor packages
Install Syncfusion.Blazor.Layouts and Syncfusion.Blazor.Themes NuGet packages in your project using the NuGet Package Manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), or the integrated terminal in Visual Studio Code (dotnet add package), or the .NET CLI.
Alternatively, run the following commands in the Package Manager Console to achieve the same.
Install-Package Syncfusion.Blazor.Layouts -Version 34.1.29
Install-Package Syncfusion.Blazor.Themes -Version 34.1.29NOTE
All Syncfusion Blazor packages are available on nuget.org. See the NuGet packages topic for details.
Add import namespaces
After the packages are installed, open the ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Layouts namespaces.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.LayoutsRegister Blazor service
Register the Blazor service in the Program.cs file of your Blazor Server App.
....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....Add stylesheet and script resources
The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet and script references in the ~/Components/App.razor file.
<link href="_content/Syncfusion.Blazor.Themes/fluent2.css" rel="stylesheet" />
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in Blazor application.
Add Blazor Dashboard Layout component
Add the Blazor Dashboard Layout component in the ~/Components/Pages/Home.razor file. If the interactivity location is set to Per page/component, define a render mode at the top of the ~Pages/Home.razor file.
NOTE
If the Interactivity Location is set to
Global, the render mode is automatically configured in theApp.razorfile by default.
@* desired render mode define here *@
@rendermode InteractiveServer@using Syncfusion.Blazor.Layouts
<SfDashboardLayout>
<DashboardLayoutPanels>
<DashboardLayoutPanel>
</DashboardLayoutPanel>
</DashboardLayoutPanels>
</SfDashboardLayout>- Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Blazor Dashboard Layout component in the default web browser.
Defining Panels
The Dashboard Layout component can be rendered with multiple panels, each designed with basic properties. Each panel typically consists of a header and a content section. These sections are defined using the HeaderTemplate and ContentTemplate properties, respectively.
Panels are interactive, supporting functionalities such as dragging, floating, and resizing.
Panels with Simple Data
A basic Dashboard Layout panel can display simple data. The panel’s header is defined by HeaderTemplate and its content by the ContentTemplate.
@using Syncfusion.Blazor.Layouts
<SfDashboardLayout>
<DashboardLayoutPanels>
<DashboardLayoutPanel>
<HeaderTemplate><div>Panel 1</div></HeaderTemplate>
<ContentTemplate><div>Content</div></ContentTemplate>
</DashboardLayoutPanel>
</DashboardLayoutPanels>
</SfDashboardLayout>
<style>
.e-panel-header {
background-color: rgba(0, 0, 0, .1);
text-align: center;
}
.e-panel-content {
text-align: center;
margin-top: 10px;
}
</style>The Dashboard Layout with simple content will be rendered in the web browser as demonstrated in the following screenshot.
Panels with Components
A Dashboard Layout can also host complex UI components such as charts, grids, maps, or gauges within its panels.
These components are placed as panel content by assigning the corresponding Blazor component element as the ContentTemplate of the panel.

NOTE
When using the SfRangeNavigator component in this sample, ensure that the Syncfusion.Blazor.RangeNavigator NuGet package is installed in your project. You can install the package from nuget.org.
To get started quickly with designing a Blazor Dashboard Layout with UI Components, you can check the video below.
By default, the Dashboard Layout component is rendered with auto-adjustable and responsive panels according to the parent dimensions.
