XtraDialog Class

A message box that allows displaying any control (e.g., a UserControl) in its client area.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v18.2.dll

Declaration

C#

public static class XtraDialog

VB.NET

Public Module XtraDialog

Remarks

To display a dialog, call the static XtraDialog.Show method. Method parameters allow you to specify a control to be displayed in its client area, provide the dialog’s caption and add predefined buttons.

The following code invokes an XtraDialog displaying a UserControl with custom controls (two TextEdit controls and one CheckEdit control), and the OK and Cancel buttons.

C#

using DevExpress.XtraEditors;
using DevExpress.XtraLayout;
using System;
using System.Windows.Forms;

namespace WindowsFormsApp1 {
    public partial class Form3 : Form {
        public Form3() {
            InitializeComponent();
        }

        private void simpleButton1_Click(object sender, EventArgs e) {
            LoginUserControl myControl = new LoginUserControl();
            DevExpress.XtraEditors.XtraDialog.Show(myControl, "Sign in", MessageBoxButtons.OKCancel);
        }
    }

    public class LoginUserControl : XtraUserControl {
        public LoginUserControl() {
            LayoutControl lc = new LayoutControl();
            lc.Dock = DockStyle.Fill;
            TextEdit teLogin = new TextEdit();
            TextEdit tePassword = new TextEdit();
            CheckEdit ceKeep = new CheckEdit() { Text = "Keep me signed in" };
            lc.AddItem(String.Empty, teLogin).TextVisible = false;
            lc.AddItem(String.Empty, tePassword).TextVisible = false;
            lc.AddItem(String.Empty, ceKeep);
            this.Controls.Add(lc);
            this.Dock = DockStyle.Fill;
        }
    }
}
