Popup - Scrolling

This demo shows two implementations of scrolling in the Popup component.

When you click the first Show Popup button, a Popup with a native scrollbar appears. The component always displays a native scrollbar when the height of the Popup's content is greater than that of the Popup.

using DevExtreme.NETCore.Demos.Models.SampleData; using Microsoft.AspNetCore.Mvc; using System; using System.Collections.Generic; using System.Linq; namespace DevExtreme.NETCore.Demos.Controllers { public class PopupController : Controller { public ActionResult Scrolling() { return View(); } } }

.label { font-size: 12px; } .demo-container { height: 450px; display: flex; align-items: center; flex-direction: column; justify-content: center; } .button-container { display: flex; align-items: center; flex-direction: column; justify-content: center; padding: 20px 0px; gap: 15px; } .dx-popup-content { font-size: 12px; } .caption { padding-bottom: 8px; font-weight: 500; } .content { display: flex; justify-content: space-between; }

A click on the second Show Popup button also displays a Popup with a scrollbar, but this scrollbar belongs to the ScrollView component. This implementation is more flexible. For example, you can enable right-to-left representation or scroll the content to a specific position. For more information about the available options, refer to the ScrollView API section.

To implement the second solution, follow the steps below:

Wrap the content in the ScrollView component and place it in the Popup container.
Set the height and width of the ScrollView to 100% of the popup content area.
