Row associated with the currency manager's position cannot be made invisible

Question

See more:

I have a DatagridView.
I have set its DataSource From a Class.

C#

taskerEntities te = new taskerEntities();
var OMsMasterDescriptiveIndicators = te.MyTable.Select(x => new lccls {Id = x.Id, name = x.name }).ToList();
MyGrid.DataSource = OMsMasterDescriptiveIndicators;

My Class is like

C#

public class lccls
    {
        public string Id { get; set; }
        public Nullable<decimal> name { get; set; }
    }

At a certain event, I want to Visible = False the current row.

C#

MyGrid.Rows[5].Visible = false;

But I am unable to do this. I think the reason is it's `datasource` associated.
So can you please help me.
How could I do this?
Is what I think about this problem is correct or not?

The Error is

>   Row associated with the currency manager's position cannot be made<br />
> invisible

maybe this is old but:
@A_Griffin
yes this way is better and there is no problem with making it visible again (@Chase Viking).

Example:

C#

var item = dgv.Rows.Cast<DataGridViewRow>().FirstOrDefault(c => c.Cells[x].Value?.ToString() == X);
            if (item != null)
            {
                availableIpsDataGridView.CurrentCell = null;
                item.Visible = false;
            }

and visibling it with:

C#

var item = dgv.Rows.Cast<DataGridViewRow>().FirstOrDefault(c => c.Cells[x].Value?.ToString() == X);
                if (item != null)
                {
                    item.Visible = true;
                }

A Google search found this[^] answer.

It looks like you have to suspend binding and then resume binding. I adapted example from the web page found at the link above.

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

I know this is a very old post, but just stumbled across it, and wanted to point out an easier way - just set this instead before setting the visibility:
MyGrid.CurrentCell = Nothing

But then if you wanted to show it again, you cannot. So, no.
