Adding an Event on Specific Date in Calendar control

In this blog you will learn how to Add an Event on specific Date in Calendar control.

DayRender event is raised while the Calendar control is being rendered, you cannot add a control that can also raise an event, such as LinkButton. You can only add static controls, such as System.Web.UI.LiteralControl, Label, Image, and HyperLink.

Add Calendar Control on to the page:Calendar.aspx:

<asp:Calendar ID="Calendar1" runat="server">
   </asp:Calendar>

Add Day Render Event:

protected void Page_Load(object sender, EventArgs e)
 {
     Calendar1.DayRender += new DayRenderEventHandler(Calendar1_DayRender);
 }

 void Calendar1_DayRender(object sender, DayRenderEventArgs e)
 {
     if (e.Day.Date.Day == 8)
     {
         e.Cell.Controls.Add(new LiteralControl("<br/>Holiday"));
     }
 }

Output:
