PDF Viewer supports customizing toolbar items, including adding, showing, hiding, enabling, and disabling items.

• Save button: The Save button can be defined using CustomToolbarItemModel and included alongside existing items via ToolbarSettings. Handle the click action using toolbarclick.

• Show or hide: The Save button can be shown or hidden using ToolbarSettings. Predefined items are listed under ToolbarItem.

• Enable or disable: The Save button can be enabled or disabled using enabletoolbaritem.

Align property

Specifies the alignment of the Save button within the toolbar:

• Left: aligns the item to the left side of the toolbar.
• Right: aligns the item to the right side of the toolbar.

Tooltip property

Sets the tooltip text for the Save button; the tooltip appears on hover.

CssClass property

Applies custom CSS classes to the Save button for styling.

Prefix property

Sets the CSS class or icon to display before the Save button text.

ID property

The id property within a CustomToolbarItemModel is required and uniquely identifies each toolbar item for configuration and interaction.

When defining or customizing toolbar items, assign a specific, descriptive id to each item. These properties are commonly used when defining custom toolbar items with CustomToolbarItemModel in the context of Syncfusion PDF Viewer. When configuring the toolbar using the ToolbarSettings property, include these properties to customize appearance and behavior.

NOTE

When customizing the Save button, icons or text can be used based on design preference.
