Use pass by value between events form

Why 80% of the code can not do farming architect? >>>  

        For example, there are two forms, Form SelectForm query information collection, using the information set DataGridview display, add and modify information EditForm form, EditForm edited and closed, positioning the row DataGridview editing SelectForm now to modify information for example, first declare an event in the form EditForm

public event EventHandler AfterEditingBillsNumber;

Then when EditForm off, or edit the information after you complete, the values ​​you want to pass a written

AfterEditingBillsNumber(label.Text, EventArgs.Empty);

Back SelectForm form, you certainly have to write a few lines of code in SelectForm

EditForm form=new EditForm();
form.ShowDialog();

Well, now that a few lines of code into this

EditForm form=new EditForm();
form.AfterEditingBillsNumber += new EventHandler(this.AfterEditingBillsNumber );
form.ShowDialog();

In this form then write event handling method AfterEditingBillsNumber

private void AfterEditingBillsNumber(object sender, EventArgs e)
{
    string focusStr = sender as string;
    if (!string.IsNullOrEmpty(focusStr))
    {
        SelectBills();
        SetFocusOnEditing(dataGridView1, "ColumnBillsNumber", "OperationsDate", focusStr);
    }
}

             }

         }
     }
