In this tutorial, I will teach you how to create a textbox programmatically in c#. This method has the ability to add an object in the form by clicking a button. It is also demonstrating how to get the collection of Controls within the control. Let's begin.

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application for c#. ps1

Step 2

Do the form just like shown below. ps2

Step 3

Press F7 to open the code editor. In the code editor, declare private variables for the location and count control.

 
        private int count_control = 0;
        private Point location_control = new Point(10, 50);

Step 4

Create a method for creating a textbox.

 
        private void createTexbox()
        {
            //    'INCREMENT THE COUNT_CONTROL.
            count_control += 1;
            //'CHECKING IF THE TEXTBOX HAS REACHED TO 6 OR NOT
            if (count_control <= 6)
            {
                // initialize a new object
                TextBox txt_new = new TextBox();
                //set a object properties
                txt_new.Name = "txt " + count_control.ToString();
                txt_new.Text = "textbox " + count_control.ToString();
                txt_new.Location = new Point(location_control.X + 10, location_control.Y);
                txt_new.Width = 350;
                location_control.Y += txt_new.Height + 10;
                // create a textbox
                Controls.Add(txt_new);
            }else
            {
                DialogResult result = MessageBox.Show("You've reached 6 controls. Do you want to clear controls to start again?", "Proceed", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
                if(result==DialogResult.OK)
                {
                    //clear the controls
                    Controls.Clear();
                    //control return to 0
                    count_control = 0;
                    // set a new point for controls
                    location_control = new Point(10, 50);
                    //create a new textbox
                    createTexbox();
                    // add button again
                    Controls.Add(button1); 
                }
            }
 
        }s

Step 5

Call the method that you have created in the first load of the form.

 
        private void Form1_Load(object sender, EventArgs e)
        {
            createTexbox();
        }

Step 6 Write the following code for creating a textbox when the button is clicked.

 
        private void button1_Click(object sender, EventArgs e)
        { 
            createTexbox();
        }
