Remove the current row from datagridview

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.

hi...

here, i wanted to write this code in cell enter event. but when i write it there its giving an error saying:
"Operation cannot be performed in this event handler."

so what i have to do now.

(i really don't know how can i reply for the answered you have given. i hope this is the way how i should do.)

thanks again..

even when i write the code in cell leave event its giving an same error as before.:confused:


and i do want to go to next row after removing the current row. so cannot use that e.Cancel = true;

as im so new to the c#, im so confused what to do.
thanks for all the answers.

if (e.KeyCode == Keys.Delete) {
	int x = DataGridView1.CurrentRow.Index;

	DataGridView1.Rows.Remove(DataGridView1.Rows(x));
}
