title: How to access list from a child within a child?
body: <p>I'm working on a program where I let the user add items to a list view. These items are then stored in a list that makes it really easy for me to load the list view on startup using a StreamReader. Now, here's my problem. The user can select an item in the list view and then click a button to show a window that basically shows more information about the item that the user has selected. In order to change, lets say, the name, I want to open yet ANOTHER window where the user can enter the new name which is then changed and saved into the list when pressing a button.</p>
  <p>I can easily access the list from the first child by sending an instance of Form1 to Form2 using a constructor. But how do I go about accessing Form1 from Form3 when Form3 is opened from Form2?</p>
  <p>I use the following code to access Form1 in Form2:</p>
  <p>Form1:</p>
  <pre><code>private void button1_Click(object sender, System.EventArgs e)
  {  
      Form2 form2 = new Form2(this);
      form2.StartPosition = FormStartPosition.CenterParent;
      form2.ShowDialog(this);
  }
  </code></pre>
  <p>Form2:</p>
  <pre><code>private Form1 _Form1;
  
  public Form2(Form1 _Form1)
  {
      this._Form1 = _Form1;
  }
  </code></pre>
