How do I pass data from child of child form to parent form?

Nov 26 2015 11:45 AM
I am new to c#. I have the following in my project in windows forms:

Form1 with button and DataGridView.

Form2 with button.

Form3 with button and 3 textBoxes.

In form1, I click buttonOpenForm2 form2 pops up. Then in form2 I click buttonOpenForm3 form3 pops up which has 3 text boxes and button. Now the 3 forms are open.

now in form3, I enter values in textBox1, textBox2 and textBox3 and when click buttonAddRow ( from form3) I want these values to be inserted into the DataGRidView in Form1.

My question is: How can I add a row into DataGridView in Form1 ( parent) from form3 (child of child form) WITHOUT closing form2 and form3? I mean I want to pass the data while form2 and form3 are still open.

Please help me. Thank you
 
 
 
Form1:   public partial class Form1 : Form
 {      
  public Form1()     
{         InitializeComponent();       
}      
 private void buttonOpenForm2 _Click(object sender, EventArgs e)     
{         
Form2 frm2 = new Form2();         
frm2.Show();     
}   
}    

Form2:   
public partial class Form2 : Form 
{     
public Form2()     
{         
InitializeComponent();     
}      
 private void buttonOpenForm3 _Click(object sender, EventArgs e)     
{         
Form3 frm3 = new Form3();         
frm3.Show();     
}      


Form3:     
public partial class Form3 : Form   
{     
public Form3()     
{        
 InitializeComponent();     
}      
 private void buttonAddRow _Click(object sender, EventArgs e)     
{         //What to write here to insert the 3 textboxes values into DataGridView?     
 }
 }
