Syncfusion Blazor Popups

This is Syncfusion's official Blazor Dialog component for building modal and modeless popups. You get the basics covered like headers, content templates, and buttons, plus the features you'd expect from an enterprise component library: draggable dialogs, resizing, fullscreen mode, and proper accessibility support. The skill walks through templates, events, positioning, and programmatic control with ShowAsync() and HideAsync() methods. It's worth noting this is a commercial component (though they have a free community license), so you're trading simplicity for a polished feature set. If you need quick alerts or confirmation dialogs with good keyboard navigation and WCAG compliance out of the box, this handles it without rolling your own modal logic.

Dialog

The Syncfusion Blazor Dialog component provides a flexible, feature-rich solution for creating modal and modeless dialogs in Blazor applications. Dialogs are essential UI elements for displaying alerts, confirmations, forms, and interactive content overlaid on the main application.

Component Overview

The Dialog component supports:

Template-based layouts (header, content, footer with custom HTML/components)
Multiple interaction modes (modal and modeless)
Rich event system (lifecycle, drag, resize, overlay interactions)
Advanced positioning (fixed, absolute, relative, centered)
Interactive features (draggable, resizable, minimize/maximize buttons, fullscreen mode)
Accessibility support (WCAG compliance, keyboard navigation, ARIA attributes)
Animations (open/close transitions)
State management (visible binding, state persistence)
