Add Toggle Button in Blazor Toolbar Component

8 Oct 202110 minutes to read

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

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

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

• Now render the toggle Button into the targeted element in the Toolbar created event handler and bind click event for it.
  On clicking the toggle Button, change the required icon and content based on current active state.
