Add MouseOver and Mouseout effect to asp.net Calendar Control

When I thought that give some interesting effect to calendar control, which will improve look and feel of the Calendar

I started working on it and I created the following code which I want to share

following is my design code....

  <div>  
     <asp:Calendar ID="Calendar1" runat="server" BackColor="White"   
       BorderColor="Black" BorderStyle="Solid" CellSpacing="1" Font-Names="Verdana"   
       Font-Size="9pt" ForeColor="Black" Height="250px" NextPrevFormat="ShortMonth"   
       onselectionchanged="Calendar1_SelectionChanged" Width="779px"   
       ondayrender="Calendar1_DayRender">  
       <SelectedDayStyle BackColor="#333399" ForeColor="White" />  
       <TodayDayStyle BackColor="#999999" ForeColor="White" />  
       <OtherMonthDayStyle ForeColor="#999999" />  
       <DayStyle BackColor="#CCCCCC" Font-Bold="true" CssClass="DayStyle" />  
       <NextPrevStyle Font-Bold="True" Font-Size="8pt" ForeColor="White" />  
       <DayHeaderStyle Font-Bold="True" Font-Size="8pt" ForeColor="#333333"   
         Height="8pt" />  
       <TitleStyle BackColor="#333399" BorderStyle="Solid" Font-Bold="True"   
         Font-Size="12pt" ForeColor="White" Height="12pt" />  
     </asp:Calendar>  
   </div>  

and the following is my code behind code where i have written DayRender event to apply MouseOver 
and Mouseout events to each cell

  protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)  
   {  
     if (!e.Day.IsToday && !e.Day.IsSelected)  
     {  
       e.Cell.Attributes.Add("onmouseover", "javascript:this.style.backgroundColor='#D4EDFF';var div=document.getElementById('myspan'); div.innerHTML=this.a.Title;;");  
       e.Cell.Attributes.Add("onmouseout", "javascript:this.style.backgroundColor='#CCCCCC'; ");  
     }  
   }
