Filter rows in DataGridView?

DataGridView

It looks like a newbie's question but it's not actually.

The problem is I just want my DataGridView's DataSource like this:

myDataGridView.DataSource = myDataSet;
myDataGridView.DataMember = "myTableName";
//however filtering its rows like this doesn't work:
myDataSet.Tables["myTableName"].DefaultView.RowFilter = "...";

Plus, myDataSet is already bound to some controls on my form and I don't want to rebind it in case that myDataGridView's DataSource changes.

If that condition is not the case, I would use the following and can filter rows OK:

//choice 1
myDataGridView.DataSource = myDataTable;
//then filter rows like this:
myDataTable.DefaultView.RowFilter = "...";

//choice 2
BindingSource bs = new BindingSource(myDataSet, "myTableName");
myDataGridView.DataSource = bs;
//then filter rows like this:
bs.Filter = "...";

I just want it as in the first code snippet. How can I filter its rows in that case?

Thank you in advance for your help!
