# Adding Controls to a Calendar Cell

There are two possible approaches for adding controls to a [ASP NET AJAX Calendar](https://www.telerik.com/products/aspnet-ajax/calendar.aspx) cell:

* You can add controls to a Day template and assign the template to one or more special days in the calendar. This approach is useful when you want to add controls on a "per day" basis. For details on how to create and use day templates, see [Day Templates](https://www.telerik.com/products/aspnet-ajax/documentation/controls/calendar/templates/day-templates).

* You can use the [DayRender](https://www.telerik.com/products/aspnet-ajax/documentation/controls/calendar/server-side-programming/events/dayrender) event to add the controls to every cell of the calendar just before it is rendered on the client:

```C#
protected void RadCalendar1_DayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e) 
{ 
    Label label = new Label();
    label.Text = e.Day.Date.Day.ToString();
    e.Cell.Controls.Add(label);
    label = new Label();
    label.Text = e.Day.Date.DayOfWeek.ToString();
    e.Cell.Controls.Add(label); 
}
```

```VB.NET
Protected Sub RadCalendar1_DayRender(ByVal sender As Object, ByVal e As Telerik.Web.UI.Calendar.DayRenderEventArgs) Handles RadCalendar1.DayRender
    Dim label As New Label()
    label.Text = e.Day.[Date].Day.ToString()
    e.Cell.Controls.Add(label)
    label = New Label()
    label.Text = e.Day.[Date].DayOfWeek.ToString()
    e.Cell.Controls.Add(label)
End Sub
```
