Answer 1

I have an example for U. I have a datagridview that may multiselected row. When i click the button to visible false row that selected. Try this:

foreach (DataGridViewRow row in dataGridView1.SelectedRows)
        {
            CurrencyManager currencyManager1 =(CurrencyManager)BindingContext[dataGridView1.DataSource];
                currencyManager1.SuspendBinding();
                dataGridView1.CurrentCell = null;
                row.Visible = false;
        }
        dataGridView1.Refresh();

Remember to set property SelectionMode: FullRowSelect

Answer 2

I know this is an old topic, but an alternative solution (my code is vb.net, but I assume it would translate)

If WO_DGV.CurrentCell.RowIndex = i Then
  'you cannot make invisible the row that is 'current'
  WO_DGV.CurrentCell = WO_DGV.Rows(i - 1).Cells("act") 
  'to get to this code I know that there is a row before i, which is why I can use i-1 as new focus
End If
WO_DGV.Rows(i).Visible = False

Maybe a little late to answer this topic but I suggest you to use DataTable.DefaultView.RowFilter property to filter what you need to show on the bounded DataGridView. Please check the following link for more informtion: https://docs.microsoft.com/en-us/dotnet/api/system.data.dataview.rowfilter?redirectedfrom=MSDN&view=netframework-4.8#System_Data_DataView_RowFilter

regards.

Answer 4

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;

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
