title: udapte datatable after RowFilter with filter results
body: <p>applying filter on a <code>datatable</code> filled with all rows from table by using <code>RowFilter</code></p>
  
  <pre><code>dtPatientInfo.DefaultView.RowFilter = string.Format("FirstLastName LIKE '%{0}%'", TB_FirstLastName.Text);
  </code></pre>
  
  <p>after applying these filter I want to update this datatable with filter result only not original data </p>
  
  <p>how I can bind the filter result to same datatable so it will lose any rows wont match the filter ?</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>as per answers and comment below I have made this but now the result data are moved to new <code>datatable</code> how move them to the old <code>datatable</code>?</p>
  
  <pre><code>if (!string.IsNullOrWhiteSpace(TB_FirstLastName.Text))
  {
      DataView dv = new DataView(dtPatientInfo);
      dv.RowFilter = string.Format("FirstLastName LIKE '%{0}%'", TB_FirstLastName.Text);
      DataTable newTable = dv.ToTable();
      dataGridView1.DataSource = newTable;
  }
  </code></pre>
