Unable To set row visible false of a datagridview

Example

        foreach (DataGridViewRow rw in dataGridView1.Rows)
        {

        if (rw.Cells[14].Value.ToString() == "") // this Cell have a TEXT, 
            {
                CurrencyManager currencyManager1 = (CurrencyManager)BindingContext[dataGridView1.DataSource];
                currencyManager1.SuspendBinding();
                rw.Visible = false; 
                currencyManager1.ResumeBinding();

            }
        }

this show only the row that have in the cell index 14, if this is blank or empty the whole row not show

After searching a lot, I got the solution

CurrencyManager currencyManager1 = (CurrencyManager)BindingContext[MyGrid.DataSource];  
currencyManager1.SuspendBinding();
MyGrid.Rows[5].Visible = false;
currencyManager1.ResumeBinding();

Cannot set yourDataGridView row visible property to false when current row index Will encounter such error if trying to hide current cell

soulution :

when yourDataGridView Data source is not null :

  CurrencyManager currencyManager1 = (CurrencyManager)BindingContext[yourDataGridView.DataSource];
                       currencyManager1.SuspendBinding();
                       yourDataGridView.Rows[Target Index].Visible = false;
                       currencyManager1.ResumeBinding();

when yourDataGridView Data source is null :

 yourDataGridView.CurrentCell = null;
 yourDataGridView.Rows[Target Index].Visible = false;
