Question

My application features a DataGridView which is attached to a simple List (which I serialize to an XML file). Changing values and adding rows works fine. However when I delete rows from the DataViewGrid the following happens:

• The selected rows disappear in the GUI
• The selected rows get removed from the BindingList
• The main List, however, remains unaltered

The following code is responsible for the deletion:

foreach (DataGridViewRow row in dataGridView.SelectedRows)
{
    dataGridView.Rows.Remove(row);
}

Answer 1

As suggested, something like this should work for you:

List<MyObject> data = dataGridView.DataSource as List<MyObject>;
data.Remove(objectToDelete);

Should be enough.
