Creating Controls Dynamically (i.e. at Runtime)

To create any control dynamically we need to perform three  steps

Step1:- Creating object for respective control class

Syntax: - ClassName ObjectName =new ClassName ( );

Example: - TextBox T1=new TextBox ( );

Step2: -  Setting the required properties to the object

Syntax: - ObjectName.PropertyName=value;

Example :- T1.BackColor=Color.Red;

                   T1.ForeColor=Color.Yellow

                   T1.Left=90;

                   T1.Top=99;

Step3: - Adding this object to the controls collection of Form class

Syntax: -this.Controls.Add(ObjectName);

Example: - this.Controls.Add(T1);

Example with Dynamic Controls:-

Add a new Form i.e.,Form2 to the Windows Application WABasics

Create one Button Control & set the following properties to It

button1:

     Text      :         Sample

     Name     :         btnSample

Design :-

 Generate the btnSample Click Event

& write the following code in Source[Form2.cs] 

using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace WABasics {     public partial class Form2 : Form     {         public Form2()         {             InitializeComponent();         }         private void btnSample_Click(object sender, EventArgs e)         {             Label L1 = new Label();             L1.Left = 100;             L1.Top = 100;             L1.Text = "Enter Any Data";             this.Controls.Add(L1);             TextBox T1 = new TextBox();             T1.Left=200;             T1.Top=100;             this.Controls.Add(T1);         }     } }

Result :-
