Quick Start Example

Basic toolbar with common formatting buttons:

@using Syncfusion.Blazor.Navigations

<SfToolbar>
    <ToolbarItems>
        <ToolbarItem Text="Cut" PrefixIcon="e-icons e-cut"></ToolbarItem>
        <ToolbarItem Text="Copy" PrefixIcon="e-icons e-copy"></ToolbarItem>
        <ToolbarItem Text="Paste" PrefixIcon="e-icons e-paste"></ToolbarItem>
        <ToolbarItem Type="ItemType.Separator"></ToolbarItem>
        <ToolbarItem Text="Bold" PrefixIcon="e-icons e-bold"></ToolbarItem>
        <ToolbarItem Text="Italic" PrefixIcon="e-icons e-italic"></ToolbarItem>
        <ToolbarItem Text="Underline" PrefixIcon="e-icons e-underline"></ToolbarItem>
    </ToolbarItems>
</SfToolbar>

Common Patterns

Pattern 1: Text Editor Toolbar

Formatting toolbar with alignment and spacing:

<SfToolbar Width="600">
    <ToolbarItems>
        <ToolbarItem Text="Bold" PrefixIcon="e-icons e-bold"></ToolbarItem>
        <ToolbarItem Text="Italic" PrefixIcon="e-icons e-italic"></ToolbarItem>
        <ToolbarItem Type="ItemType.Separator"></ToolbarItem>
        <ToolbarItem Type="ItemType.Spacer"></ToolbarItem>
        <ToolbarItem Text="Left" PrefixIcon="e-icons e-align-left"></ToolbarItem>
        <ToolbarItem Text="Center" PrefixIcon="e-icons e-align-center"></ToolbarItem>
        <ToolbarItem Text="Right" PrefixIcon="e-icons e-align-right"></ToolbarItem>
    </ToolbarItems>
</SfToolbar>

Pattern 2: Responsive Toolbar with Popup

Toolbar that moves overflow items to a popup:

<SfToolbar Width="400" OverflowMode="OverflowMode.Popup">
    <ToolbarItems>
        <ToolbarItem Text="Cut" PrefixIcon="e-icons e-cut" Overflow="OverflowOption.Show"></ToolbarItem>
        <ToolbarItem Text="Copy" PrefixIcon="e-icons e-copy" Overflow="OverflowOption.Show"></ToolbarItem>
        <ToolbarItem Text="Paste" PrefixIcon="e-icons e-paste"></ToolbarItem>
        <ToolbarItem Type="ItemType.Separator"></ToolbarItem>
        <ToolbarItem Text="Bold" PrefixIcon="e-icons e-bold"></ToolbarItem>
        <ToolbarItem Text="Italic" PrefixIcon="e-icons e-italic"></ToolbarItem>
    </ToolbarItems>
</SfToolbar>

Pattern 3: Dynamic Toolbar with Add/Remove

Toolbar with programmatic item management:

<SfToolbar>
    <ToolbarItems>
        @foreach (var item in ToolbarItems)
        {
            <ToolbarItem Text="@item.Text" PrefixIcon="@item.Icon"></ToolbarItem>
        }
    </ToolbarItems>
</SfToolbar>

@code {
    private List<ToolbarItemData> ToolbarItems = new()
    {
        new() { Text = "Cut", Icon = "e-icons e-cut" },
        new() { Text = "Copy", Icon = "e-icons e-copy" }
    };
    
    private void AddItem()
    {
        ToolbarItems.Add(new() { Text = "Paste", Icon = "e-icons e-paste" });
    }
    
    private void RemoveItem()
    {
        if (ToolbarItems.Count > 0)
            ToolbarItems.RemoveAt(0);
    }
    
    public class ToolbarItemData
    {
        public string Text { get; set; }
        public string Icon { get; set; }
    }
}

Pattern 4: Toolbar with Custom Alignment

Left-aligned, center-aligned, and right-aligned items using Spacer:

<SfToolbar>
    <ToolbarItems>
        <ToolbarItem Text="File"></ToolbarItem>
        <ToolbarItem Text="Edit"></ToolbarItem>
        <ToolbarItem Type="ItemType.Spacer"></ToolbarItem>
        <ToolbarItem Text="Help"></ToolbarItem>
        <ToolbarItem Type="ItemType.Spacer"></ToolbarItem>
        <ToolbarItem Text="Settings" PrefixIcon="e-icons e-settings"></ToolbarItem>
        <ToolbarItem Text="Profile" PrefixIcon="e-icons e-user"></ToolbarItem>
    </ToolbarItems>
</SfToolbar>

Implementation Guidelines

When Configuring Items

1. Use appropriate item types: Button for actions, Separator for visual dividers, Spacer for alignment, Input for custom controls
2. Add icons for better UX: Use PrefixIcon for icon-only or icon-with-text buttons
3. Provide tooltips: Set TooltipText for icon-only buttons to improve accessibility
4. Consider responsive behavior: Choose appropriate OverflowMode based on target devices
5. Set overflow priorities: Use Overflow property to control which items move to popup first

When Handling Overflow

1. Scrollable mode (default): Best for desktop applications with horizontal space
2. Popup mode: Ideal for mobile or limited-width containers
3. MultiRow mode: Good for toolbars with many related items
4. Extended mode: Similar to MultiRow but with different layout behavior

When Customizing Appearance

1. Use built-in icons: Leverage Syncfusion icon library with e-icons class
2. Apply themes consistently: Use CssClass for custom styling
3. Consider accessibility: Maintain sufficient color contrast and focus indicators
4. Test responsive behavior: Verify toolbar appearance at different widths

When Implementing Dynamic Behavior

1. Use data binding: Bind ToolbarItems to a collection for dynamic updates
2. Handle events: Use OnClick for button actions
3. Update state conditionally: Toggle Disabled or Visible properties based on application state
4. Manage item lifecycle: Add or remove items from the bound collection to update the toolbar

Common Use Cases

1. Rich Text Editors: Formatting toolbars with bold, italic, alignment, lists
2. File Managers: Action bars with upload, download, delete, rename buttons
3. Data Grids: Command toolbars for add, edit, delete, export operations
4. Image Editors: Tool palettes with drawing, cropping, filter tools
5. Navigation Menus: Top-level navigation with menu items and search
6. Dashboard Controls: Action buttons for refresh, filter, settings
7. Form Builders: Component palettes with draggable controls

Tips and Best Practices

• Icon-only buttons: Always provide TooltipText for accessibility
• Responsive design: Test toolbar at various widths to verify overflow behavior
• Keyboard navigation: Enable TabIndex for better keyboard accessibility
• Visual grouping: Use Separator to create logical groups of related items
• Performance: When using many items, consider Popup mode to reduce initial render size
• Custom templates: Use Template property for complex controls beyond standard buttons
• Alignment flexibility: Prefer Spacer over Align property for more dynamic layouts

Next Steps

After implementing the basic toolbar:

1. Explore responsive modes to handle different screen sizes
2. Add keyboard navigation with TabIndex for accessibility
3. Customize styling to match your application theme
4. Implement dynamic item management for interactive toolbars
5. Add toggle buttons or custom controls using templates
6. Integrate with other Syncfusion components (DropDownList, ColorPicker, etc.)
