Hi,

I m building a windows application and I want to update the checked rows of the datagridview in the database. I have tried many options but m not getting the result as i want. Following is my code that i m trying :

C#

foreach (DataGridViewRow dr in dgvPendingApprovals.Rows)
{
    int rid = int.Parse(dgvPendingApprovals[1, dr.Index].Value.ToString());

    DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
    ch1 = (DataGridViewCheckBoxCell)dgvPendingApprovals.Rows[dgvPendingApprovals.CurrentRow.Index].Cells[0];
    if (ch1.Value == null)
        ch1.Value = false;
    switch (ch1.Value.ToString())
    {
        case "True":
            ch1.Value = false;
            break;
        case "False":
            cmd.CommandText = "Update ApplicantDetails set Status2 = 'Yes', ApprovedDate2 =  getdate() where Id = '" + rid + "'";
            cmd.Connection = conobj.getConn();
            conobj.openCon();
            cmd.ExecuteNonQuery();
            conobj.closeCon();
            rid = 0;
            MessageBox.Show(rid + " Updated");
            break;
    }

}

I want that for each datarow that for datarow whose checkbox.check value is true, that row should get updated. But when using this code only the row that is selected gets updated, not the one whose checkbox is checked. Please help me with a solution for this.
