BindingSource.DataSource Problem

I've been struggling with a problem for days.

I always try to let Visual Studio take care of the binding by dragging and dropping tables on to a form. Then Fill() does the rest.

this.tblTriCntrsTableAdapter.Fill(this.processDataSet.tblTriCntrs);

I added a line in Fill in the commandText DataSet.xsd file by adding  WHERE (InActive = 'false')

The binding source is automatically created.

In this case I needed two binding sources where the DataMember = tblTriCntrs and the DataSource = processDataSet.

So I renamed the original and created a second just like the original. Except they have different names and filters.

tblTriCntrs1BindingSource.Filter = "TricanterNum = 1";
tblTriCntrs2BindingSource.Filter = "TricanterNum = 2";

There is never more than one record with "Inactive = false" for each binding source. And sometimes just one or neither have a record where "Inactive =false"

This all works well everywhere in a fairly substantial program.

Except where I need to let the user scroll through closed / "Inactive = true" records.

So I create a temporary table "tblREVIEW1" to load just one record at a time where "Inactive = true" and this works well for viewing the closed records.

I change the Data Source like this: tblTriCntrs1BindingSource.DataSource = tblREVIEW1;

When the user is done scrolling I reset the Data Source back the way it was like this:tblTriCntrs1BindingSource.DataSource = this.processDataSet.tblTriCntrs;

This is where I'm having problems.

For some reason the above filters are no longer working after changing the data source back to the way it was.

DataRowView drv1 = (DataRowView)tblTriCntrs1BindingSource.List[0];
DataRowView drv2 = (DataRowView)tblTriCntrs2BindingSource.List[0];

Both drv1 and drv2 point to the same record even though drv1's filter should make it not point to any records because there is no  "TricanterNum = 1" WHERE (InActive = 'false') They all = 'true'

I tried Load() again and resetting the filters after the load but nothing works.

Sorry for all this. I just hope this make sense and someone can help me get the binding sources back on track.

Thank you.
