ya correct.. currently m doing, i have create one list and stored into bin file.. so if i register one user with password itz successfully stored all data and showing in DGV. but the problem is the "the dVG shows password also", i need to stored all data and the same time i need to hide password from datagridview also.. is it possible?

final answer

private void btnDelete_Click(object sender, EventArgs e)
{

bool flag = false;
int x = 0;
Log lecObj = new Log();
lecObj.Username = txtname.Text;

for (; x < list.Count; x++)
{
lecObj = list[x];
if (lecObj.Username == txtname.Text);
{
flag = true;
break;
}
}
list.RemoveAt(dtvregister.SelectedRows[x].Index);
Stream stream = File.Open("Login.bin", FileMode.Create);
BinaryFormatter bformatter = new BinaryFormatter();
bformatter.Serialize(stream, list);
stream.Close();

btnGetDetails_Click(sender,e);
}

i have given the errors above

Error 1 The best overloaded method match for 'System.Collections.Generic.List<xyz_system.log>.RemoveAll(System.Predicate<xyz_system.log>)' has some invalid arguments

No errors found. but is not deleting from list.. why?

i have insert some modify.. and this error message came ( Rows cannot be programmatically removed unless the DataGridView is data-bound to an IBindingList that supports change notification and allows deletion.)

for (int i = dtvregister.SelectedCells.Count - 1; i >= 0; i--)
{
dtvregister.Rows.RemoveAt(dtvregister.SelectedCells[i].RowIndex);
}

The dataGridView showing details...old details.. no any changes in datagridview
