Think your problem is here:
textBox2.Name = "textBox2";
create a couter that gives all of the controls a unique name.
And you might want to us mouse down and position to place your control or something like that

hii,
just
change z+25 to z+=25 and define x and z globally it will run successfully.

modified code

C#

public partial class Form1 : Form
   {
       int x = 27, z = 65;
       public Form1()
       {
           InitializeComponent();
       }
       private void button1_Click(object sender, EventArgs e)
       {
           TextBox textBox2 = new TextBox();
           textBox2.Name = "textBox2";
           textBox2.Location = new Point(x, z += 25);
           textBox2.Visible = true;
           this.Controls.Add(textBox2);
       }
   }

Have you heard about loops?

C#

int i = 1, x=27, y=65;
for (i = 0; i < 5; i++ )
{
  TextBox tb = new TextBox();
  tb.Name = "textBox" + i.ToString();
  tb.Location = new Point(x, y + 25 * i);
  tb.Visible = true;
  this.Controls.Add(tb);
}

Hi,
See you code below:

C#

int x=27, z=65;
private void button1_Click(object sender, EventArgs e)
{
    TextBox textBox2 = new TextBox();
    textBox2.Name = "textBox2";
    textBox2.Location = new Point(x,z+25);
    textBox2.Visible = true;
    this.Controls.Add(textBox2);
}

You are adding the code dynamically, correct. Your problem is, you are adding the controls in the same location again and again. Try putting the different location for the buttons each time you are adding. Try this:

C#

int x=27, z=65;
private void button1_Click(object sender, EventArgs e)
{
    TextBox textBox2 = new TextBox();
    textBox2.Name = "textBox2";
    textBox2.Location = new Point(x,z+25);
    textBox2.Visible = true;
    this.Controls.Add(textBox2);
    z += 20;
    y += 20;
}

Hope it helps.

Your code is correct
control is added on every click but it's overlapping due to location property is every time same.
so, it's look like no new control added
just location should be change
Happy coding!
:)
