Une solution pour les non-WPF DataGrid:

//Create DataTable
DataTable dt = new DataTable();
//Put some columns in it.
dt.Columns.Add(new DataColumn("Item #", typeof(int)));
dt.Columns.Add(new DataColumn("Contract Number", typeof(string)));
dt.Columns.Add(new DataColumn("Customer Name", typeof(string)));
//Create the record
DataRow dr = dt.NewRow();
dr["Item #"] = i;
dr["Customer Name"] = xmn2[1].InnerText;  //value from textbox on screen
dr["Contract Number"] = xmn4[1].InnerText; //value from textbox on screen
dt.Rows.Add(dr);
//Bind the GridView to the data in the data table for display.
this.GridView1.Visible = true;
GridView1.DataSource = dt;
GridView1.DataBind();
