Question

I have the below code which is attempting to modify each row in a DataTable but after the loop over the rows where modification takes place, when I look at the rows collection the column LOCATION is empty even though the loop just populated it. Can anyone help?

        dtBoxes.Columns.Add("LOCATION");

        dtBoxes.DefaultView.Sort = "PALLETID";
        foreach (DataRow row in dtBoxes.DefaultView.ToTable().Rows)
        {
            var locationRow = dtLocations.Select("ID = " + row["ID"].ToString());
            if (locationRow != null)
            {
                row["LOCATION"] = locationRow.First()["LOCATION"].ToString();
            }
        }

I don’t know much about DataViews but I would guess that the ToTable() is creating new instances of the rows.

Try modifying the loop to

foreach (DataRowView row in dtBoxes.DefaultView)
{
    //....
}
