Example domainUpDown control in windows form c#

How to use doaminUpDown Control
  1. First of all add domainUpDown control from ToolBox
  2. Copy this code paste into your code file

    private void Form2_Load(object sender, EventArgs e)
        {
            DomainUpDown.DomainUpDownItemCollection collection = this.domainUpDown1.Items;
            collection.Add("Jan");
            collection.Add("Feb");
            collection.Add("Mar");
            collection.Add("Apr");

            //How to set the text default in DomainUpDown

            this.domainUpDown1.Text = "Jan";

        }


The Last line of code explain the default value of domainUpDown Control. 
In the Second example, I will explain you how to retrieve value from domainUpDown Control using SelectedItemChanged.

        private void domainUpDown1_SelectedItemChanged(object sender, EventArgs e)
        {
            MessageBox.Show(domainUpDown1.Text);
        }

When, first time the page is load then appear message box on your screen with the text message of selected item of domainUpDown Control.

Now, Learn how to add domainUpDown control using code file. Also learn how to fire SelectedItemChanged event using code file.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApplication3
{
    public partial class Form3 : Form
    {
        public Form3()
        {
            InitializeComponent();
        }

        private void Form3_Load(object sender, EventArgs e)
        {
            DomainUpDown dynamicallyadd = new DomainUpDown();
            dynamicallyadd.Location = new System.Drawing.Point(12, 50);
            dynamicallyadd.Name = "domainupdown";
            dynamicallyadd.Width = 250;
            dynamicallyadd.Height = 100;
            dynamicallyadd.Items.Add("Apple");
            dynamicallyadd.Items.Add("mango");
            dynamicallyadd.Items.Add("Grapes");
            dynamicallyadd.Text = "Apple";
            this.Controls.Add(dynamicallyadd);
            dynamicallyadd.SelectedItemChanged += new System.EventHandler(Itemchanged);
        }

        private void Itemchanged(object sender, EventArgs e)
        {
           // throw new NotImplementedException();
            DomainUpDown item = sender as DomainUpDown;
            MessageBox.Show(item.Text);
        }
    }
}



Now, In this last section of the domainUpDown Control, we will learn how to bind it with Database table. If you bind it with SQL server then  first to add EDMX file in the project.

      private void Form1_Load(object sender, EventArgs e)
        {
            BankingSystemEntities bs = new BankingSystemEntities();
            var item = bs.userAccounts.ToArray();
            foreach (var item1 in item)
            {
                domainUpDown1.Items.Add(item1.Account_No.ToString());
            }
