title: Multiple parameter in Row Filter
body: <p>I am trying to put a textbox as an Rowfilter under a textchanged event !</p>
  
  <p>The code below is used to GRID to get the appropriate <code>Reg_Number</code> <strong>or</strong> <code>Customer_Name</code> which is entered in the text box! </p>
  
  <p>wat's the surprising fact is, this code directly takes the 2nd Argument</p>
  
  <p>(i.e)<br>
  <code>((DataTable)radGridView1.DataSource).DefaultView.RowFilter = "Reg_Number like '%" + radTextBoxControl1.Text + "%'";</code></p>
  
  <p>tried to switch the lines, but no matter what i did, it ignores the 1st one and takes the 2nd</p>
  
  <p>i tried to put AND to get both in a single line, bt din't work, plz hel me frnzz!</p>
  
  <pre><code>private void radTextBoxControl1_TextChanged(object sender, EventArgs e)
  {
      try
      {
          ((DataTable)radGridView1.DataSource).DefaultView.RowFilter =
              "Customer_Name like '%" + radTextBoxControl1.Text + "%'";
          ((DataTable)radGridView1.DataSource).DefaultView.RowFilter =
              "Reg_Number like '%" + radTextBoxControl1.Text + "%'";
      }
      catch (Exception) { }
  }
  </code></pre>
