How to perform style changes on datagridview rows using rows from the underlying bindingsource?

should help you out This is what I am trying to achieve: , How about this:

DataTable changedRecordsTable = dataTable1.GetChanges();

around this issue Here is my answer, I don't really understand this but I've just tried and it works like a charm.
My rule is:

wish helps you Its a Windows Form Application. Database is MS Access. Using Typed DataSet. I am having a datagridview, which i only use to insert data into database. I want to clear all the rows added as soon as I click on Reset Button on my form. The datagridview is using bindingSource. The Binding Source is using a Typed DataTable from the Typed DataSet , For the following scenario

this.dataGridViewPurDetails.DataSource = this.purchaseDetailBindingSource; 
// purchaseDetailBindingSource 
// this.purchaseDetailBindingSource.DataMember = "PurchaseDetail";
this.purchaseDetailBindingSource.DataSource = this.tVDataSet;

BindingSource DT = (BindingSource)dataGridViewPurDetails.DataSource; 
if (DT != null) 
    ((TVDataSet)DT.DataSource).PurchaseDetail.Clear();

will help you I think you must add your new object to the bindingSource yourself. I created a simple version of your project, with only 2 DGV. I also set the Data Source Update Mode to "Never" in my dataGridView2 -> DataBindings -> Advanced
When I write a new FileMoveProcessDetails (in the right grid) I can save it clicking a button and calling this code:

private void button1_Click(object sender, EventArgs e)
{
    var myCurrentRow = dataGridView2.Rows[dataGridView2.CurrentRow.Index];
    var fmpd = myCurrentRow.DataBoundItem;
    var pp = (FileMoveProcess)processesBindingSource.Current;
    pp.SourceDetails = (FileMoveProcessDetails)fmpd;
}

I wish this helpful for you Before reading the answer, you should know if you don't have a bool field or something to detect which job is completed it's not a good design. You should have a single list of jobs. Then based on a bool field you should show incomplete jobs in first grid and completed jobs in second grid. Then the filter would be simply Completed = true and Completed = false.
Anyway, you can use IN in filter expression. It's enough to create a list of values which you want to use in filter, then create the filter this way:

var ids = this.dataGridView2.Rows.Cast<DataGridViewRow>()
                .Where(r => !r.IsNewRow)
                .Select(r => r.Cells[0].Value.ToString());
bs1.Filter = string.Format("Column1 NOT IN ({0})", string.Join(",", ids));

.Select(r => string.Format("'{0}'",r.Cells[0].Value.ToString()));
