DataGridView - Load very slow in windows server 2008

I have a form with Datagridview that load data from db to binding source and then set binding source as `DataSource` of datagrid 
I call `SuspendBinding()` and set `RaiseListChangedEvents` to false before fill data from db and when data fill call `ResumeBinding()` and `ResetBindings(false)` and set `RaiseListChangedEvents` to true 

    newPriceListSelectBindingSource.RaiseListChangedEvents = false;    newPriceListSelectBindingSource.SuspendBinding();    newPriceListSelectTableAdapter.Fill(dsOrders.NewPriceListSelect, null, int.Parse(trvCategory.SelectedNode.Name), Convert.ToInt32(numericUpDown1.Value));    newPriceListSelectBindingSource.RaiseListChangedEvents = true;    newPriceListSelectBindingSource.ResumeBinding();    newPriceListSelectBindingSource.ResetBindings(false);

in many windows operating systems when filling data finished, `resetbindings(false)` call immediately, but in windows server 2008 r2 this method call very very slow (it seem to program hangs). 
of course I'm not sure this depends on windows. 
data rows is about 80000 rows in 20 columns. 
Please help me to solve this problem.
