Generate TextBox Dynamically at Runtime in Windows Form Application

In this blog, we generate a textbox at the runtime. We give the quantity of the textbox that we want to generate in the TextBox. It will generate the textbox.

Step 1:

Open visual studio -> File -> New -> Project -> WindowsFormApplication

Step 2:

Drag panel1, panel2, textBox1 and button from a toolbox window.


Step 3:

Now, Double click on the click me button and write the following code:

try
{
    int
txtno = int.Parse(txt1.Text);
    int
pointX = 30;
    int
pointY = 40;
    panel2.Controls.Clear();
    for
(int i = 0; i < txtno; i++)
    {
        TextBox
a = new TextBox();
        a.Text = (i + 1).ToString();
        a.Location = new Point(pointX, pointY);
        panel2.Controls.Add(a);
        panel2.Show();
        pointY += 20;
    }
}
catch
(Exception)
{
    MessageBox
.Show(e.ToString());
}

Step 4:

Press F5 and run. Enter the no in the textbox, and it will generate the textbox.

For eg: if, here, we enter 4 in the textbox, then it will generate 4 textboxes.
