Change Value of Cell of DataGridView

I have 2 forms:

Form1 contains DataGridView.
Form2 contains Textboxes, radioButton and Button.

When I select DataGridView Row it will show me Form2 and Displayed their values in TextBoxs . Every Thing seems better just now.
What I want know is after displaying datas in textboxes , I check the RadioButton then click in the button it will return to Form1 of The selected Row and Change The value of Cell 5.

Here there is My code:

Form1

private void dataGridView1_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
{
DataGridViewCell cell = null;
foreach (DataGridViewCell selectedCell in dataGridView1.SelectedCells)
{
cell = selectedCell;
break;
}
if (cell != null)
{
DataGridViewRow row = cell.OwningRow;
string objet = row.Cells[0].Value.ToString();
string objectif = row.Cells[1].Value.ToString();
string date = row.Cells[2].Value.ToString();
string commentaire = row.Cells[3].Value.ToString();
string client = row.Cells[5].Value.ToString();
string commercial = row.Cells[6].Value.ToString();
Détails_RDV détails = new Détails_RDV();
détails.obj = objet;
détails.objectif = objectif;
détails.date = date;
détails.comm = commentaire;
détails.clt = client;
détails.commer = commercial;
détails.Show();
}
}

Form2

public partial class Détails_RDV : Form
{
public string obj ;
public string objectif;
public string date;
public string comm;
public string clt ;
public string commer;
public Détails_RDV()
{
InitializeComponent();
}
private void Détails_RDV_Load(object sender, EventArgs e)
{
txtObjet.Text = obj;
txtObjectif.Text = objectif;
txtDate.Text = date;
txtCommerci.Text = commer;
txtClient.Text = clt;
txtCommentaire.Text = comm;
}
private void btnValider_Click(object sender, EventArgs e)
{
if (radBtnEffectue.Checked == true)
{
//What should I write here??
}
}

How Can I do That ?

Please help, Thanks in Advance

Hi Vinay,
The Textboxes are not able to write in , I want to change it automatically just when I click to Button

Hi
Simply you can do one thing just rebind the grid if you are making changes in form2 and saving the record.

gvdatagridview.Rows[Rownumber].Cells[index].Value.ToString ()=newvalue;
I assume that you want to change that value of gridview on selection
