What I have tried:

I added data:

private void add_data()
       {
            DataTable dt = new DataTable();
            ListItem_nv.Clear();
            dt = CMD_hengio.Show_hengio();
 foreach (DataRow Row in dt.Rows)
            {
                Item_hengio item= new Item_hengio();
                item.name_nv    = Row[1].ToString();
                item.ip_thuchien= Row[2].ToString();
                item.time       = ((DateTime)Row[3]).ToString("HH:mm:ss");// Row[3].ToString("HH:mm:ss"); 
                item.date_start = ((DateTime)Row[4]).ToString("dd/MM/yyyy");
                item.date_end   =((DateTime)Row[6]).ToString("dd/MM/yyyy");
                item.repeat     = Row[5].ToString();
                item.notes      = Row[9].ToString();
                item.status     = Row[8].ToString();
                item.tag_item = Row[0].ToString() + "*" + Row[7].ToString(); // add tag. 
                if (item.status == "Unfulfilled") item.Name_color = "Yellow";
                if (item.status == "Processing") item.Name_color = "Green";
                if (item.status == "Stop") item.Name_color = "Red";
                if (item.status == "Pause") item.Name_color = "YellowGreen";
                if (item.notes == "Error date")
                {
                    item.Color_Notes = "Red";
                }
                if (item.notes == "Error timer")
                {
                    item.Color_Notes = "Red";
                }
                else
                    item.Color_Notes = "#FF477067";
                ListItem_nv.Add(item); 
            }
            Datagrid.ItemsSource = ListItem_nv;
            ICollectionView view = CollectionViewSource.GetDefaultView(ListItem_nv);
            view.Refresh();
}
