Hello good day I have an existential question, I am filling a DataGrid by means of a query in C# windows forms , Which shows me in a column several ID , and by middle of the function CellDoubleClick in the DataGrid I am showing a window in which I intend to show in a Textbox the number of ID that I select from the DataGrid only that I do not remember how to pass that value as a parámetro to the new form where is the textbox , someone can help me, I'm stopped at this time. I leave the code of how I'm doing it.

Form1

       private void dgvInfoNomina_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
            try
            {
                frmTimbraNomina objTimbrar = new frmTimbraNomina();
                objTimbrar.ShowDialog();
            }
            catch (Exception ex)
            {
                ex.ToString();
            }
        }
        public string EnviarId(string nomina)
        {           
            string IdNomina = "";
            IdNomina = dgvInfoNomina.CurrentCell.Value.ToString();
            return IdNomina;
        }

Form2

 public void MostrarId()
    {
        frmMuestraNomina objMostrar = new frmMuestraNomina();
        objMostrar.EnviarId()
    }

c#

I guess you want something like this:

private void dgvInfoNomina_CellDoubleClick(object sender, DataGridViewCellEventArgs e){
int col_ID = 0; //suponiendo que el id se encuentre en la columna 0
string id = (string)dgvInfoNomina[e.RowIndex, col_ID].Value;
//Llamas a tu form y le pasas el id como parametro
}

There are many ways to do this. I'll leave an option in steps:

Crear una variable Publica in the Form2 of the desired type, in this case String

public String valor;

In the Load of Form2 assign the valor of the variable to the TextBox desired.

private void Form2_Load(object sender, EventArgs e)
{
    textBox1.Text = valor;
}

In the Form1 in the Double_Click , create e Instanciar the Form2 , then through that instance access the variable value that was created and assign the value of the selected cell.

private void dgvInfoNomina_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
try
  {
    Form2 frm= new Form2();
    frm.valor = dgvInfoNomina.CurrentCell.Value.ToString();
    frm.ShowDialog();
  }
catch (Exception ex)
  {
        ex.ToString();
  }
