The ASP.NET Core Dialog is a useful user interface (UI) control for informing users about critical information, errors, warnings, and questions, as well as confirming decisions and collecting input from users. The control has a rich set of built-in features such as action buttons, positioning, animations, dragging, resizing, templating, and more with mobile dialog support. The dialog provides two different types: modal dialogs and non-modal dialogs (modeless) based on interactions.
The ASP.NET Core dialog control comes with two different types of dialogs, modal and non-modal (modeless):
The ASP.NET Core dialog control provides built-in support to perform actions through buttons, which define necessary callback functions to handle user input.
Modal dialogs create overlays on open modal windows that provide options for a user to control the closing behavior of a dialog while interacting with it.
Users can launch multiple dialogs simultaneously or one above the other based on their z-index (z-depth) to make additional dialogs (nested modal dialogs).
A variety of smooth, built-in animations are available to configure for the opening and closing of modal dialogs. They perform based on CSS3 animation from the Animation library.
The modal dialog can resize from any of the edges or borders of the dialog within the target container by using its handle (grip) or hovering on it.
The modal dialog can be closed by clicking on a close icon, with an overlay click, or by pressing the ESC key. Users can restrict the closing behavior of a dialog based on its callback function parameters, also.
Create ASP.NET Core alerts and confirmation dialogs by using built-in functions.
The ASP.NET Core dialog control supports right-to-left (RTL) rendering. Users can change the text direction and layout of the dialog control from right to left. This improves the user experience and accessibility for those who use RTL languages.
Fully supports WAI-ARIA accessibility, which helps dialogs be accessed by on-screen readers and assistive devices.
Follows WAI-ARIA Best Practices for implementing keyboard interaction.
The UI element visuals such as foreground color, background color, line spacing, text, and images were designed based on the WCAG 2.0 standard.
The ASP.NET Core dialog control is highly configurable to make mobile dialogs and better user experiences across phone, tablet, and desktop form factors.
The ASP.NET Core dialog control has several built-in themes such as material, bootstrap, fabric (Office 365), and high contrast. Users can customize any one of these built-in themes or create new themes to achieve their own desired look and feel either by simply overriding SASS variables or using our Theme Studio application.
Developers can control the appearance and behaviors of a dialog, including its positioning, content, and animation, using a rich set of APIs.
