The following sample code can be used to get the value of the ID column within the third data row (this row's handle is equal to 2).

C# VB

string cellValue; cellValue = gridView1.GetRowCellValue(2, "ID").ToString();

// Create an empty list.
ArrayList rows = new ArrayList();
// Add the selected rows to the list.
for (int i = 0; i < gridView1.SelectedRowsCount; i++) {
   if (gridView1.GetSelectedRows()[i] >= 0)
      rows.Add(gridView1.GetDataRow(gridView1.GetSelectedRows()[i]));
}
try {
   gridView1.BeginUpdate();
   for (int i = 0; i < rows.Count; i++) {
      DataRow row = rows[i] as DataRow;
      // Change the field value.
      row["Discontinued"] = true;                             
   }
}
finally {
   gridView1.EndUpdate();
}    

 

How to get the GridView selected objects

To get all selected objects in the GridView, you should iterate via all selected rows, get row handles, and then by using the GetSelectedRows method get the selected row object itself.
