Overview

The Blazor Spinner component denotes when long-running tasks are ongoing, tasks for which there is no information about their progress. The component provides circular progress indicators without interaction capabilities.

To show users the progress information of a task, the Blazor ProgressBar component should be used, instead.


Built-in types

Several built-in, Sass-based themes are available: Tailwind CSS, Bootstrap 5, Bootstrap 4, Bootstrap, Material, Fabric, and high contrast. Simplify theme customization by either overriding the existing Sass styling or creating custom themes using the Theme Studio application.


Descriptive labels

Include labels with the Blazor Spinner component that give additional, meaningful information about the task currently running.


Spinner intergration

The Spinner component can be rendered with other Blazor components, such as the Tab component. To render the Spinner inside the Tab component, the Spinner is set as a child of the Tab component, and the Spinner can be shown or hidden when switching between tabs.

Various sizes

Adjust the size of the Blazor Spinner component to large, medium, or small to help integrate it within other Blazor components.


Templates

Using a template, users can create a custom Blazor loading component.


Visibility

You can control the Blazor Spinner component’s visibility easily through a two-way binding property and asynchronous methods.


Customization

The default appearance of the Blazor Spinner component can be customized by changing its color and stroke width. Also, you can set the z-index for Blazor spinners dynamically based on application scenarios.

We do not sell the Blazor Spinner separately. It is only available for purchase as part of the Syncfusion Blazor suite, which contains over 80 Blazor components, including the Spinner. A single developer license for the Syncfusion Essential Studio for Blazor suite costs $995.00 USD, and includes one year of support and updates.

No, our 80+ Blazor components, including Spinner, are not sold individually, only as a single package. However, we have competitively priced the product so it only costs a little bit more than what some other vendors charge for their Spinner alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 80+ Blazor components for a flat fee of $995/developer. On top of this, we might be able to offer additional discounts based on currently active promotions. Please contact our sales team today to see if you qualify for any additional discounts.

No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue and five or fewer developers.

A good place to start would be our comprehensive getting started documentation.
