Bonjour,

voici mon code qui ne marche pas.

*******************************
private DataTable CreerTable()
        {

            DataTable result = new DataTable("facbest");

            result.Columns.Add(new DataColumn("Date", Type.GetType("System.DateTime")));

            result.Columns.Add(new DataColumn("Apport", typeof(string)));
            result.Columns.Add(new DataColumn("Jeux", typeof(string)));
            result.Columns.Add(new DataColumn("Gains", typeof(string)));
            result.Columns.Add(new DataColumn("Pertes", typeof(string)));
            result.Columns.Add(new DataColumn("Crédit", typeof(string)));

            return result;

        }

        private void mainDataGridView_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            DateTime data = DateTime.Now;

            string date  =  data.ToLongDateString ();
        
            if (mainDataGridView.Columns[e.ColumnIndex].Name == "Date")
            {
                date = mainDataGridView[e.ColumnIndex, e.RowIndex].Value.ToString ();
            }
        }

*********************************
En faisant un click sur une cellule date je voudrais afficher la date du jour sans l'heure.

Merci d'avance

date.ToShortDateString();
date.ToString("dd/MM/yyyy);

Bonsoir,

*****************************
DateTime data = DateTime.Now;

            string date  =  data.ToShortDateString();
        
            if (mainDataGridView.Columns[e.ColumnIndex].Name == "Date")
            {
                date = mainDataGridView[e.ColumnIndex, e.RowIndex].Value.ToString ();
            }
****************************

private void mainDataGridView_CellClick(object sender, DataGridViewCellEventArgs e) 

à ce bout de code.

  private void AjouteLigneATable(string LigneLue, DataTable TableDeDonnees)
        {

            int index = 0;
    
            string[] valeursLues = LigneLue.Split(new char[] { ';' });
           
            DataRow ligneDeDonnees = TableDeDonnees.NewRow();
           
            foreach (string valeur in valeursLues)
            {
                switch (index++)
                {
                    case 0:
                        ligneDeDonnees["Date"] = valeur.Trim();
                        break;
                    case 1:
                        ligneDeDonnees["Apport"] = valeur.Trim();
                        break;
                    case 2:
                        ligneDeDonnees["Jeux"] = valeur.Trim();
                        break;
                    case 3:
                        ligneDeDonnees["Gains"] = valeur.Trim();
                        break;
                    case 4:
                        ligneDeDonnees["Pertes"] = valeur.Trim();
                        break;
                    case 5:
                        ligneDeDonnees["Crédit"] = valeur.Trim();
                        break;
                   

                    default:
                        ligneDeDonnees[string.Format("Colonne {0}", index)]= valeur.Trim();
                        break;
                       
                }
            }
