Learning > ui > core > Dialog Edit this page Dialog The Dialog React component displays a floating dialog with optional resizing and dragging functionality. Properties The many Dialog properties, as defined in DialogProps, control resize and move capabilities, header, footer, placement, sizing, event handlers and custom styling. The opened prop, which is the only mandatory prop, indicates whether to show the dialog. The resizable prop indicates whether the user can resize the dialog. The default is false. The movable prop indicates whether the user can move the dialog. The default is false. The inset prop indicates whether the content should be inset. The default is true. Header and Footer The title prop specifies the text to show in the header, or title bar, of the dialog. The buttonCluster prop is a list of DialogButtonDef objects specifying buttons and associated onClick events. These buttons display in the footer at the bottom of the dialog. The header can be hidden using the hideHeader prop. The header can be overridden using the header prop. The footer can be overridden using the footer prop. This overrides the buttonCluster prop. Placement The alignment prop indicates where to align the dialog. The default is DialogAlignment.Center. The x prop specifies the initial x/left position of dialog in px. The y prop specifies the initial y/top position of dialog in px. Sizing The width prop specifies the initial width of dialog. Displayed in px if value is a number; otherwise, it is displayed in specified CSS unit. The default is "50%". The height prop specifies the initial height of dialog. Specified in px if value is a number; otherwise, it is displayed in specified CSS unit. The minWidth prop specifies the minimum width that the dialog may be resized to. Default is 300px. The minHeight prop specifies the minimum height that the dialog may be resized to. Default is 100px. The maxWidth prop specifies the maximum width that the dialog may be resized to. The maxHeight props specifies the maximum height that the dialog may be resized to. Event Handlers The onClose handler function is called when the 'X' button for dialog is clicked or touched. The onEscape handler function is called on a 'keyup' event for the Esc key. The onOutsideClick handler function is called when a click/touch occurs outside of the dialog. Modeless Dialogs By default, a Dialog is modal. A Dialog may be specified as modeless (non-modal) by setting the modal prop to false. Modeless dialogs require an id specified by the modelessId prop and an implementation of the onModelessPointerDown prop. Custom Styling Several props may be used to override styling. The backgroundStyle prop specifies CSS properties for the background overlay. The titleStyle prop specifies CSS properties for the title. The footerStyle prop specifies CSS properties for the footer. The contentClassName prop specifies a CSS class name for the content area. The contentStyle prop specifies CSS properties for the content area. API Reference Dialog Last Updated: 12 June, 2024
