How to add toggle button in Blazor Toolbar

14 Aug 20267 minutes to read

Toolbar supports adding a toggle button by using the Template property.

• By using Toolbar’s Template property, pass the required HTML String to render the toggle button.

<Template>
    <SfButton></SfButton>
</Template>

• Render the SfButton with the IsToggle property set to true inside the Template, and use a click event handler to update the icon and content based on the toggle state.
