Add a Button Control Pragrmatically in C#

Submitted by donbermoy on Saturday, July 19, 2014 - 11:58.
Today in C#, we will create a program that will add a button pragmatically in windows form using C#. Now, let's start this tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio 2010: Go to File, click New Project, and choose Windows Application. 2. You don't have to design a button in your form because we will just code to have a button when loading the form. 3. Put this code in your code view.
  1. //set a class variable to be used during the form
  2. private int Count_control = 0;
  3. private Point Location_control = new Point(10, 50);
After that, create a method for creating a Button.
  1. private void create_button()
  2. {
  3.        
  4.         //increment the count_control.
  5.         Count_control += 1;
  6.         //checking if the buttons has reached to 5 or not
  7.         if (Count_control <= 5)
  8.         {
  9.                 //set a new button
  10.                 Button new_Button = new Button();
  11.                 //add the properties of the button
  12.                 new_Button.Name = "Button" + Count_control.ToString();
  13.                 new_Button.Text = "Button" + Count_control.ToString();
  14.                 new_Button.Location = new Point(Location_control.X + 10, Location_control.Y);
  15.                 new_Button.Width = 180;
  16.                 Location_control.Y += new_Button.Height + 10;
  17.                 //create the event handler
  18.                 new_Button.Click += new System.EventHandler(myButtonHandler_Click);
  19.                 //add the new button to the collection of controls
  20.                 Controls.Add(new_Button);
  21.         }
  22.         else
  23.         {
  24.                
  25.                 //checking if you want to clear the controls that you have added.
  26.                 if (MessageBox.Show("You\'ve reached 5 controls. Do you want to clear controls to start again?", "Proceed", MessageBoxButtons.OKCancel, MessageBoxIcon.Information) == Windows.Forms.DialogResult.OK)
  27.                 {
  28.                        
  29.                         Controls.Clear(); //clearing the control
  30.                         Count_control = 0; //returning the count_control to its default value
  31.                         Location_control = new Point(10, 50); //set a new point of the controls
  32.                         create_button(); //put a control so that you can add another controls
  33.                 }
  34.         }
  35. }
Then, create a subroutine that handles the click events of the Buttons.
  1. private void myButtonHandler_Click(object sender, EventArgs e)
  2. {
  3.         //verifying the buttons
  4.         if (sender is Button)
  5.         {
  6.                 create_button(); //create a new button
  7.                
  8.         }
  9. }
Lastly, you have to put your method that you have created in the first load so that the button will appear in the Form.
  1. private void Form1_Load(System.Object sender, System.EventArgs e)
  2. {
  3.         create_button();
  4. }
