How to pass flag from childform to parent?

Can any body help me to send the values from childForm to parentForm. I have declared an int id variable in parentForm, now I want to send the textbox1.Text value from childForm to that int variable of parentForm.

Answer 1

You can make id a public property and assign the value in child form.

In parent form

//Declare public property 
public string ID { get; set; }

//Create child form in some method.
Form2 form2 = new Form2(this);
form2.Show();

In child form

Form1 m_parent ;
public Form2(Form1 frm1)
{ 
     InitializeComponent(); 
     m_parent = frm1; 
}

m_parent.ID = textbox1.Text;
