PopupContainerEdit() Constructor

Creates an instance of the PopupContainerEdit class.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v23.2.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

public PopupContainerEdit()

VB.NET

Public Sub New

Remarks

The constructor allows you to create a PopupContainerEdit editor at runtime. This initializes all properties to their default values.

The editor is created with a single ButtonPredefines.Combo button type. Clicking the button invokes the popup window and displays its associated popup control. Use the RepositoryItemPopupContainerEdit.PopupControl property to specify the control to display in the popup.

Example

The following example creates a PopupContainerControl with a RichTextBox inside, and assigns this control to a PopupContainerEdit editor.

C#

using DevExpress.Utils;
using DevExpress.XtraEditors;
using DevExpress.XtraEditors.ViewInfo;
using System;
using System.Data;
using System.Windows.Forms;

namespace DXApplication10 {
    public partial class Form1 : DevExpress.XtraEditors.XtraForm {
        public Form1() {
            InitializeComponent();
            // ...
            this.Load += Form1_Load;
        }

        private void Form1_Load(object sender, EventArgs e) {
            CreatePopupEditor();
        }

        void CreatePopupEditor() {
            RichTextBox rtb = new RichTextBox();
            rtb.Dock = DockStyle.Fill;
            PopupContainerControl popupControl = new PopupContainerControl();
            popupControl.Controls.Add(rtb);

            PopupContainerEdit editor = new PopupContainerEdit();
            editor.Location = new Point(100, 30);
            editor.Width = 350;
            editor.Properties.PopupControl = popupControl;
            Controls.Add(editor);

            editor.Closed += (s, a) => {
                (s as PopupContainerEdit).EditValue = rtb.Text;
            };

            editor.CustomDisplayText += (s, x) => {
                if (x.Value != null)
                    x.DisplayText = x.Value.ToString().TrimStart(' ', '\r', '\n');
            };
        }
    }
}
