Supposing the name of the Datagrid used is dgvGrid
Now to remove the currently selected row please use the following code


||ly you cam remove row at any index by writing the row index you want to remove

You can use Row validating event.

Check in database for duplication. Now if dont want user to enter that garbage value, Turn e.Cancel = True it will not allow user to go for next row.

It will not remove row but it will not allow to for next one.

private void dataGridView1_RowValidating(object sender, DataGridViewCellCancelEventArgs e)
if (dataGridView1.Rows[e.RowIndex].Cells["name"].Value.ToString() == "test")
MessageBox.Show("can't enter");
e.Cancel = true;


Just test this code.
Hope it will work for u.
