Hello Everybody,

While loading the form i am retrieving values from database and showing in datagridview . when i click save,all the values are being updated .It is working fine.But i have many rows so performance is slow.
This is code i am using and it is working fine.
foreach (DataGridViewRow examinationlistrow in dgvExamination.Rows)
                string _examinid = examinationlistrow.Cells[0].Value.ToString();
                string _examinvalue = examinationlistrow.Cells[3].Value.ToString();
                UpdateListItem(mrid, ic, _examinid, _examinvalue);

But i want to update only changed values of the datagridview.

I suggest add a new column in datagridview Like "Action", when editing a column
you change the Action column value to "Edit"(you can use Datagridview cellendedit event).

When inserting time you put a condition
IF (examinationlistrow.Cells["Action"].Value.ToString() == "Edit")
