    dv.RowFilter = string.Format("TRANSACTYPE  LIKE '%{0}%'", cboFilter.SelectedItem.ToString());
    dataGridView1.DataSource = dv;

If you need DataGridView data source always to be a DataTable as in my case.

DataTable dt = (DataTable)dgv.DataSource;
dgv.DataSource = dt.Select("IsActive = 1").CopyToDataTable();
