Príklad prepojenia TextBox-u s dátami:

this.textBox1.DataBindings.Add("Text",this.myList,"UserName");

 Vytvoríme si this.myList , ktorý obsahuje list objektov z triedy ClassUser. Ak sa zmení hodnota UserName, tak sa nám to hneď prejaví v TextBox-e a opačne, ak zmeníme údaj v TextBoxe, tak sa nám automaticky zmení aj v UserName.

Môžeme prepojiť aj inú vlastnosť napr. Checked v CheckBoxe:

this.checkBox1.DataBindings.Add("Checked",this.myList,"IsAdmin");

Pri prepojení ComboBox-u s Listom musíme ešte nastaviť DisplayMember :

this.comboBox1.DataSource = this.myList;
this.comboBox1.DisplayMember = "UserName";

Ak chceme prepojiť vlastnosť typu int s TextBoxom :

System.Windows.Forms.Binding b1 = new System.Windows.Forms.Binding("Text",this.myList,"Age");
b1.Format += new ConvertEventHandler(b1_Format);
this.textBox1.DataBindings.Add(b1);

		void b1_Format(object sender, ConvertEventArgs e)
		{			
		    if (e.Value.GetType() != typeof(string)) return;
		
		    string value1 = (string)e.Value;
		
		    try
		    {
		        e.Value = Convert.ToInt16(value1);
		    }
		    catch(Exception ex)
		    {
		        MessageBox.Show(ex.Message);
		    }
		}

Trieda ClassUser :

	public class ClassUser
	{
			public string UserName{get;set;}
			public string LoginName{get;set;}
			public string Info{get;set;}
			public int Age{get;set;}
			public bool IsAdmin{get;set;}
	}
