if(!IsPostBack)
{
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Sex");
dt.Columns.Add("Age");
//DataRow dr = dt.NewRow();
object[] dr = new object[4];
dr[1] = "张三";
dr[2] = "男";
dr[3] = "21";
for (; i < 10005; i++)
{
dr[0] = i.ToString();
dt.Rows.Add(dr);
}
this.gvTest.DataSource = dt;
this.gvTest.DataBind();
