Working with controlls on different forms

Working with controlls on different forms

  Just be sure you note that if you have multiple copies of F2 open, this will not work. This technique works well if you know you only have one copy of that form open.

  yes make the checkbox on form 2 public.. you can do that by modifing manually the form2.designer.cs or in the Propreties windows at the Design tab set modifiers to public
  
  acessing the checkbox from form1
  
  1)make a instance of form2
  Form2 form2=new Form2();
  2)modifing the checkbox
  form2.checkBox1.Checked=false;

  Hello
  
  There is a simple solution exits for it
  
  in the Button Click Event of Form1 , write the following code
  
  private void button1_Click(object sender, EventArgs e)
  {
  Form2 f2 = (Form2)Application.OpenForms["Form2"];
  f2.checkBox1.Checked = true;
  
  }
  
  this will return the current running instance of Form2, and then checked the checkbox, make sure that the checkbox is public.
  
  Hope this might help

  You can better create a property on your Form2 to encapsule it.
  
  

  public class Form2 : Form { private CheckBox _chkPriorityShipment; public bool PriorityShipment { get { return _chkPriorityShipment.Checked; } set { _chkPriorityShipment.Checked = value; } } }

  
  
  Now, you only have one extra property and nobody can set the checkbox like when you just using the public modifier. Using the public modifier has a lot of side effects, every property can be set of the checkbox outside when you make him public. Or even worse, it can be initialized outside!
  So use a property to encapsule it.
  
  Usage:
  

  private void button1_Click(object sender, EventArgs e) { Form2 form = (Form2)Application.OpenForms["Form2"]; form.PriorityShipment = true; }
