The C1Dialog control is a special type of dialog window that can be created on the client-side or server-side to display information and receive input from the user. You can use C1Dialog to create modal or modeless dialog windows by calling either the Open() methods.

Dialog windows can be used to:

• Prompt users for additional information when using items that require user input.
• Retrieve input for an application.
• Display information or options relative to the application while the user works in another window.

Feature Overview

C1Dialog provides several unique features including, a rich object model, Modal and Modeless Dialog windows, Partial Page Rendering, style properties, built-in themes, template support, HTML content, external content, window positioning, minimizing options, movable dialog windows, and resizable dialog windows.

• Modal and Modeless Dialog Windows
  Dialog for ASP.NET Web Forms provides two different types of dialog windows: Modal and Modeless dialog windows. A modal dialog window is a child window that must be closed before the user can continue working on the current application. A modeless dialog window enables users to interact with other windows while the dialog window is present. For more information on these types of dialog windows see, Modal and Modeless Dialog Windows.
• Partial-Page Rendering
  Improve application performance and provide more direct feedback when users perform actions with Partial Page Rendering (PPR) technology.
• Docking
  The dialog box can be docked to zones when the window is minimized.
• Styles
  Dialog for ASP.NET Web Forms provides unique property styles for its caption bar and content elements.
• Template Support
  Templates can be added to the content area of the dialog window. Dynamic Templates can be used in the content area of the dialog window for achieving rich presentation of the dialog window. For more information on templates, see Content Templates.
• Animation
  ustomize interaction with the dialog using any of the built-in animation effects. Change how the dialog window is shown and hidden, and how the dialog window expands and collapses. By default, the dialog window does not use any animation effects.
• Theming
  With just a click of the SmartTag, change the dialog box's look by selecting one of the 5 premium themes (Midnight, Aristo, Rocket, Cobalt, and Sterling). Optionally, use ThemeRoller from jQuery UI to create a customized theme! For more information on this feature, see Themes.
• CSS Support
  Use a cascading style sheet (CSS) style to define custom skins. CSS support allows you to match the window to your organization's standards.
