row validating not letting form to close if a new row added

Question

after validating if all fields are available in a datagridview row, using RowValidating event; if the user accidently clicks on a new row, then the validations are triggered and not letting form to close. Below is the code private void dgv1_RowValidating(object sender, DataGridViewCellCancelEventArgs e) { if (dgv1.CurrentRow != null) { DataGridViewRow dgvRow = dgv1.CurrentRow; if (dgvRow.Cells["txtEmpName"].Value == DBNull.Value) { MessageBox.Show("Employee Name cannot be empty"); e.Cancel = true; } } } the user enters one row successfully and clicks on next row. then row validation triggers and not letting form to close.

out of the 5 columns , i need name field not to be empty. The adress fields could be empty. so i added code to Row Validating event of the datagrid view, to check if name column is not null. if its null, there is a messagebox to alert it cannot be empty. but in case after entering a correct row, user clicks tab and new row came up in the datagrid view; and user want to close the form; it alerts "name cannot be empty" and unable to close the form. how can we handle this ? Below is the code private void dgv1_RowValidating(object sender, DataGridViewCellCancelEventArgs e) { if (dgv1.CurrentRow != null) { DataGridViewRow dgvRow = dgv1.CurrentRow; if (dgvRow.Cells["txtEmpName"].Value == DBNull.Value) { MessageBox.Show("Employee Name cannot be empty"); e.Cancel = true; } } }
