LINQ

hi,

If you are using window base application than it possible to get the data from Grid view.

DataTable dTable = dataGridView1.DataSource as DataTable;

var results = from myRow in dTable .AsEnumerable()
where myRow.Field("RowNo") == 1
select new
{
       field1 = p.Field("field1"),
       Field2 = p.Field("field2")                        
};

now you have data table you can write Linq query to find perticular record.
also you can use traditional way for loop.

foreach (DataGridViewRow row in dataGrid.Rows)
    {

         foreach (DataGridViewCell cell in row.Cells)
        {
            string value = cell.Value.ToString();

        }
    }
hope this will help you.
