If it were me, I'd handle the checkbox click event, and set a bool IsChecked property in the actual object bound to the grid, and then you could simply use Linq on the object itself.

var count = (from item in itemCollection
             where item.IsChecked && item.Tytle == "household"
             select item).Count();

That would make it much simpler.

Solution 1

C#

IList<GridViewRow> rows = new List<GridViewRow>();
      foreach (GridViewRow item in gvPerson.Rows)
      {
          //Enter Condition Here
          rows.Add(item);
      }
      IEnumerable<GridViewRow> irows = rows.AsEnumerable<GridViewRow>();
      Response.Write(string.Format("Numeber of Rows Using LINQ:{0}", irows.Count()));
