Need help in date control

hello friend,
try this code
using System.Drawing;

public partial class DefaultCS : System.Web.UI.Page
{
protected void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
{
// Select all dates in the past
if (e.Day.Date < System.DateTime.Today)
{
// Disable date
e.Day.IsSelectable = false;
// Change color of disabled date
e.Cell.ForeColor = Color.Gray;
  } 
}
}
