closeOnOutsideClick
A Boolean value specifying whether or not the UI component is closed if a user clicks outside of the popover window and outside the target element.
Event (jQuery or EventObject)
The event that caused UI component closing. It is a dxEvent or a jQuery.Event when you use jQuery.
The function passed to this property enables you to specify a custom condition for UI component closing. For instance, you can prevent closing until a user clicks a certain element.
jQuery
$(function () { $("#popoverContainer").dxPopover({ // ... closeOnOutsideClick: function(e) { return e.target === $("#someElement").get()[0]; } }); });
Angular
import { DxPopoverModule } from "devextreme-angular"; // ... export class AppComponent { // ... closeOnOutsideClick(e) { return e.target === document.getElementById("someElement"); } } @NgModule({ imports: [ // ... DxPopoverModule ], // ... })
<dx-popover ... [closeOnOutsideClick]="closeOnOutsideClick"> </dx-popover>
The closeOnOutsideClick function is called when a user clicks the UI component or outside it.

import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxPopoverModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxPopoverModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }

position
An object defining UI component positioning properties.
You can use the position.of property and the Popover's target property to specify the element against which the UI component will be positioned. If you set both these properties, position.of takes precedence.
Besides the position configuration object, the property can take on the following string values, which are shortcuts for the corresponding position configuration.
- "top" - places the popover over the target element
- "bottom" - places the popover under the target element
- "left" - places the popover to the left of the target element
- "right" - places the popover to the right of the target element
rtlEnabled
When this property is set to true, the UI component text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.
DevExpress.config({ rtlEnabled: true });
