  • 2 minutes to read

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

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');
            };
        }
    }
}
