Solution 2

On button click event for c# , do the following

C#

private void button1_Click(object sender, EventArgs e)
{
    DateTimePicker dtp = new DateTimePicker();
    //add the new datetimepicker below the previous one
    dtp.Location = new Point(dateTimePicker1.Location.X, dateTimePicker1.Location.Y+25);
    Button btn = new Button(); // add a new button
    btn.Size = button1.Size; //set button size
    btn.Text = "+"; // set button text
    btn.Location = new Point(button1.Location.X, button1.Location.Y+25);
    this.Controls.Add(dtp);
    this.Controls.Add(btn);
}

You would be able to add more controls like this to your form if you want, Won't you?

call the same function with every "+" button click event. You don't need to create different event handlers for every button click. just call the same function.

I am currently working on the solution that you want but i have been unable to figure it out. I am a student myself. I hope you can wait or you may try repeating your question again in the forum.

Ya thanks for help but I Found the solution. I repeatedly called same event.
I was making mistake that in event i was giving controls position with respect to first controls. I just took positions of all controls in variables and with each button click i Kept on increamenting y-coordinate of all controls positions
so all controls came on new line. initially they where overlapping so was unable to get controls on new line on every click.
