Getting Started with Blazor Dashboard Layout Component in Web App
29 Nov 202420 minutes to read
This section briefly explains about how to include Blazor Dashboard component in your Blazor Web App using Visual Studio.
Prerequisites
Create a new Blazor Web App
You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.
You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.
Install Syncfusion® Blazor Layouts and Themes NuGet in the Blazor Web App
To add Blazor Dashboard Layout component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.Layouts and Syncfusion.Blazor.Themes.
If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.
Alternatively, you can utilize the following package manager command to achieve the same.
Install-Package Syncfusion.Blazor.Layouts -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33NOTE
Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.
Register Syncfusion® Blazor Service
Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.Layouts namespace.
@using Syncfusion.Blazor
@using Syncfusion.Blazor.LayoutsNow, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App. For a app with WebAssembly or Auto (Server and WebAssembly) interactive render mode, register the Syncfusion® Blazor service in both ~/Program.cs files of your web 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 reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:
<head>
....
<link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>
....
<body>
....
<script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>NOTE
Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.
Add Syncfusion® Blazor Dashboard Layout component
Add the Syncfusion® Blazor Dashboard Layout component in .razor file inside the Pages folder. If an interactivity location as Per page/component in the web app, define a render mode at top of the component, as follows:
@* desired render mode define here *@
@rendermode InteractiveAuto<SfDashboardLayout>
<DashboardLayoutPanels>
<DashboardLayoutPanel>
</DashboardLayoutPanel>
</DashboardLayoutPanels>
</SfDashboardLayout>- Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Dashboard Layout component in your default web browser.
Defining panels
A dashboard layout can be rendered with multiple panels to design a template with its basic properties.
A dashboard layout panel consists of two sections, which are Header and Content section. HeaderTemplate is used to render the Header section and ContentTemplate is used to render the content section.
Also, it is easy to interact with the panels by dragging, floating, and resizing functionality of panels.
Panels with simple data
A dashboard layout panel is rendered with simple data. The header of a panel is defined by HeaderTemplate and content of a panel is defined by ContentTemplate.
<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 be rendered with the components like the chart, grids, maps, gauge, and more as a content of dashboard layout panel.
These complex data (components) are placed as the panel content by assigning the corresponding component element as the ContentTemplate of the panel.
@using Syncfusion.Blazor.Charts
@using Syncfusion.Blazor.Grids
@using Syncfusion.Blazor.Layouts

To get started quickly with designing a Blazor Dashboard Layout with UI Components, you can check the video below.
By default, the dashboard layout control is rendered with auto adjustable and responsive according to the parent dimensions.
