RadDatePicker, RadTimePicker, RadDateTimePicker and RadMonthYearPicker expose the ChildrenCreated server event, which occurs after the child controls are created.

Caution
ChildrenCreated can be wired only during the Page_PreInit event, since it is fired before the regular handlers are attached.

TheChildrenCreated event handler receives two arguments:

1. The control whose children have just been created. This argument is of type object, but can be cast to the appropriate type.

2. A DefaultViewChangedEventArgs object. This object has the following two properties:

   • OldView is the CalendarView object for the view that was current before the change.

   • NewView is the CalendarView object for the current view after the change.

You can use this event to set date input, calendar and time view properties, or add additional controls. The following example uses the ChildrenCreated event handler to add a control that clears the selection:

• C#
• VB.NET

CopyC#

protected void RadDatepicker1_ChildrenCreated(object sender, System.EventArgs e)
{
    RadDatePicker picker = (RadDatePicker)sender;
    HyperLink clearLink = new HyperLink();
    clearLink.NavigateUrl = string.Format("javascript:$find('{0}').Clear()", picker.ClientID);
    clearLink.Text = "Clear";
    picker.Controls.Add(clearLink);
}

CopyVB.NET

 

Protected Sub RadDatePicker1_ChildrenCreated(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadDatePicker1.ChildrenCreated
    Dim picker As RadDatePicker = DirectCast(sender, RadDatePicker)
    Dim clearLink As New HyperLink()
    clearLink.NavigateUrl = _
      String.Format("javascript:$find('{0}').Clear()", picker.ClientID)
    clearLink.Text = "Clear"
    picker.Controls.Add(clearLink)
End Sub
