I solved like this
if (myGridView.Rows.Count > 0)
{
var dt = new DataTable();
dt.Columns.Add("Column1", typeof(string));
dt.Columns.Add("Column2", typeof(Int64));
dt.Columns.Add("Column3", typeof(string));
foreach (GridViewRow row in gd_endYearSchool.Rows)
{
var id = row.Cells[1].Text;
//for find textbox
var tb1 = row.Cells[2].FindControl("tbNr") as TextBox;
int nrord = 0;
if (tb1 != null)
{
var ord = tb1.Text;
if (!Int64.TryParse(ord, out nrord))
{
nrord = 0;
}
}
var text=row.Cell[3].text;
dt.Rows.Add(id,nrord,text);
}
}
