Telerik UI for Windows Phone by Progress

RadDatePicker allows for defining a default value that will be displayed in the popup when the Valueproperty is not initialized.

Defining a default popup value

RadDatePicker exposes the PopupDefaultValue property that can be used to define a default value for the popup. The following XAML code snippet demonstrates setting the PopupDefaultValue:

<telerikInput:RadDatePicker x:Name="radDatePicker" PopupDefaultValue="03/04/2012"/>

If no PopupDefaultValue is set the Date part of the DateTime.Now value is used.
