Implementing the Syncfusion Blazor Stepper Component

The Blazor Stepper component provides an intuitive way to guide users through multi-step processes. It displays progress across numbered or labeled steps, supporting linear and non-linear workflows with customizable animations, templates, and validation states.

When to Use This Skill

Use the Stepper component when you need to:

• Create multi-step wizards or workflows
• Display progress through sequential tasks
• Build step-by-step forms with validation
• Implement checklist-style navigation
• Guide users through onboarding processes
• Show optional vs. required steps
• Validate step completion before progression

Component Overview

The Stepper displays steps in a horizontal or vertical layout with configurable indicators, labels, and templates. Each step can be customized with:

• Visual states: Not started, in progress, completed, error
• Labels and icons: Custom text and CSS icon classes
• Validation: Success or error indicators
• Templates: Custom content for advanced layouts
• Animations: Smooth transitions between steps

Quick Start Example

@using Syncfusion.Blazor.Navigations

<SfStepper>
    <StepperSteps>
        <StepperStep Label="Cart" IconCss="sf-icon-cart"></StepperStep>
        <StepperStep Label="Address" IconCss="sf-icon-transport"></StepperStep>
        <StepperStep Label="Payment" IconCss="sf-icon-payment"></StepperStep>
        <StepperStep Label="Ordered" IconCss="sf-icon-success"></StepperStep>
    </StepperSteps>
</SfStepper>

Common Patterns

Linear Workflow

Use the Linear property to enforce sequential progression—users can only move to the next step after completing the current one.

<SfStepper Linear="true">
    <!-- Steps -->
</SfStepper>

Active Step Control

Set the ActiveStep property to control which step is currently active (0-indexed).

<SfStepper ActiveStep="1">
    <!-- Steps -->
</SfStepper>

Tracking Step Changes

Handle the StepChanged event to respond when users navigate between steps.

<SfStepper StepChanged="@OnStepChanged">
    <!-- Steps -->
</SfStepper>

@code {
    private void OnStepChanged(StepperChangedEventArgs args)
    {
        // Handle step change
    }
}

Validation States

Display success or error states using the IsValid property on individual steps.

<StepperStep Label="Payment" IsValid="true"></StepperStep>
<StepperStep Label="Confirm" IsValid="false"></StepperStep>

Key Properties

Step Properties:

• Label: Display text for the step
• Text: Alternative text content
• IconCss: CSS class for custom icons
• Disabled: Prevents interaction with the step
• Optional: Marks step as optional
• IsValid: Sets validation state (true/false/null)
• Status: Current state (NotStarted, InProgress, Completed)
• CssClass: Custom CSS class for styling

Common Use Cases

Checkout Flow: Guide users through purchase steps with validation and error handling.

Form Wizards: Break complex forms into manageable steps with optional sections.

Onboarding: Create step-by-step tutorials for new users with progress tracking.

Setup Wizards: Guide users through configuration processes with success/error states.

Task Lists: Display checklist-style progress with completed/pending indicators.
