C#

Here is the code I used to demonstrate the problem:

From the project 'starter':

<code>
using System;
using System.Windows.Forms;
using FormPart;

namespace starter
{
  public class starter
  {
    [STAThread]
    static void Main() 
    {
      try
      {
        Application.Run(new FormFormPart());
      }
      catch (Exception e)
      {
        MessageBox.Show("Exception Caught", "starter Message");
      }
    }
  }
}
</code>
From the project FormPart in the namespace FormPart which has a populated DataGrid object:
<code>
private void button1_Click(object sender, System.EventArgs e)
{
  dataView2.RowFilter = "Distance Like 'a'";
}
</code>
