  This is my approach.
  
  Create a class to hold the parameters that you want to pass; adjust to your needs.
  
      public class myDataClass
      {
          public string txt1 = "";
          public string txt2 = "";
      }
  
  In the editor form, add a variable to hold the data and add a second constructor that will take data. Changes highlighted
  
      public partial class Form2 : Form
      {
          myDataClass data;
  
          public Form2()
          {
              InitializeComponent();
          }
  
          public Form2(myDataClass theData)
          {
              InitializeComponent();
              data = theData;
          }
          ...
          ...
      }
  
  Also add a form_load event handler to the editor form that will populate the controls of the editor form
  
          private void Form2_Load(object sender, EventArgs e)
          {
              if (data != null)
              {
                  textBox2.Text = data.txt1;
              }
          }
  
  Lastly add a method to the editor form to retrieve the modified data
  
          public myDataClass getData()
          {
              data = new myDataClass();
              data.txt1 = textBox2.Text;
  
              return data;
          }
  
  In the form where you want to call the editor form to edit an existing record
  
          private void buttonEdit_Click(object sender, EventArgs e)
          {
              // store data for transfer
              myDataClass theData = new myDataClass();
              theData.txt1 = textBox1.Text;
  
              // create form2
              Form2 frm2 = new Form2(theData);
              // and show it
              frm2.ShowDialog();
              // get the modified data
              theData = frm2.getData();
              // do something with it
  
  
              // get rid of form2
              frm2.Dispose();
          }
  
  In the form where you want to call the editor form to create a new record
  
          private void buttonNew_Click(object sender, EventArgs e)
          {
              // create form2
              Form2 frm2 = new Form2();
              // and show it
              frm2.ShowDialog();
              // get the data
              myDataClass theData = frm2.getData();
              // do something with it
  
              // get rid of form2
              frm2.Dispose();
          }
  
  I hope that this shows the basics of what your looking for. Adjust to your needs.

  Hi, I have this...
  
  
          private void btnDodaj_Click(object sender, EventArgs e)     // Add
          {
              frmKoordinatoriUI frmVanjski = new frmKoordinatoriUI("", "");  // send nothing...
              frmVanjski.Name = "Unos";     // Name of form, Volpes give me idea... important
              frmVanjski.ShowDialog();
              PopuniGrid();
          }
  
  
          private void btnIzmjeni_Click(object sender, EventArgs e)  // Edit
          {
              var red = this.dgvKoordinatori.CurrentCell.RowIndex;
  
  
              frmKoordinatoriUI frmVanjski = new frmKoordinatoriUI(dgvKoordinatori.Rows[red].Cells[0].Value.ToString(), dgvKoordinatori.Rows[red].Cells[1].Value.ToString());
              frmVanjski.Name = "Izmjena";  // Name of form, Volpes give me idea... important
              frmVanjski.ShowDialog();
              PopuniGrid();
          }
  
  
  and in frmKoordinatoriUI.....    // add/edit form...
  
  public partial class frmInvestitoriUI : Form
      {
          Investitor ulagac = new Investitor(); class like your suggest
  
  
          /*
           * s0 - id
           * s1 - naziv investitora
           * s2 - adresa
           * s3 - OIB
           * k1-k5 - kontakti
           */
          public frmInvestitoriUI(string s0, string s1, string s2, string s3, string k1, string k2, string k3, string k4, string k5)
          {
              InitializeComponent();
  
  
              // "preuzimanje" podataka...
              ulagac.id = s0;
              ulagac.naziv = s1;
              ulagac.adresa = s2;
              ulagac.oib = s3;
              ulagac.kontakt1 = k1;
              ulagac.kontakt2 = k2;
              ulagac.kontakt3 = k3;
              ulagac.kontakt4 = k4;
              ulagac.kontakt5 = k5;
          }
  
  
          private void frmInvestitoriUI_Load(object sender, EventArgs e)
          {
              if (this.Name == "Izmjena")   // control Name of form !!!!!!! add or edit depend on Name
              {
                  this.Text = "Izmjena podataka o investitoru";
                  Priprema();         // priprema polja za uredenje podataka...
              }
          }
  
  
  But I want to use this form for 4 DGV views... Now, I think to put all methods and properties from class in form!!! And forgot evrithing. Just call form with arguments and all logic is in form. Not good idea??
