Вы также можете создать пользовательский элемент управления, который наследует от исходного DatePicker.
public class MyDatePicker : Microsoft.Phone.Controls.DatePicker
{
public string PickerPageHeader
{
get { return (string)GetValue(PickerPageHeaderProperty); }
set { SetValue(PickerPageHeaderProperty, value); }
}
// Using a DependencyProperty as the backing store for PickerPageHeader. This enables animation, styling, binding, etc...
public static readonly DependencyProperty PickerPageHeaderProperty =
DependencyProperty.Register("PickerPageHeader", typeof(string), typeof(MyDatePicker)
, new PropertyMetadata("Choose date text in your language"));
public MyDatePicker()
{
base.PickerPageUri = new Uri("/Sample;component/CustomControls/MyDatePickerPage.xaml?Header=" + PickerPageHeader, UriKind.Relative);
//Don't forget to change the project name and xaml location
}
}
И создайте файл xaml страницы выбора в папке CustomControls:
<toolkit:DatePickerPage
x:Class="Sample.MyDatePickerPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"
/>
Код позади:
public partial class MyDatePickerPage : Microsoft.Phone.Controls.DatePickerPage
{
public MyDatePickerPage ()
{
InitializeComponent();
foreach (var item in base.ApplicationBar.Buttons)
{
IApplicationBarIconButton button = item as IApplicationBarIconButton;
if (null != button)
{
if ("DONE" == button.Text.ToUpper())
{
button.Text = "done in your language";
}
else if ("CANCEL" == button.Text.ToUpper())
{
button.Text = "cancel in your language";
}
}
}
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
(base.FindName("HeaderTitle") as TextBlock).Text = e.Uri.OriginalString.Substring(e.Uri.OriginalString.IndexOf("Header=") + 7);
base.OnNavigatedTo(e);
}
}
