Hey based on your requirement you can change the below code

Drop a Place holder where u want the checkbox to appear ,

Set Autopostback property of dropdown =true

and then add the below code (for sample only) to you selectedindex changed event

C#

protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
 {
     CheckBox chk = new CheckBox();
     chk.Checked = false;
     chk.Text = DropDownList2.SelectedItem.Text;
     PlaceHolder1.Controls.Add(chk);
 }
