DataGridView

I have a table called selling, with a column called DateTime in it which, cunningly enough, contains date and times. Now, I want to filter my DataGridView, but when I press the button to filter the item, the Windows Forms application freezes.

Here's my query:

private void button1_Click_1(object sender, EventArgs e)
{
  sellingBindingSource1.Filter = string.Format(
    "SELECT * FROM Selling WHERE DateTime BETWEEN '10/21/2010' AND 
    '10/22/2010'");
}
