i have a problem with WPF Binding. I want to bind a list of Months to a ItemsControl that shows a Calendar Control for each month. But each rendered Calendar shows DateTime.Now,not the bound DateTimes. Does anyone know why this is happening?
This is what i have so far:
The MainWindow.xaml
<Window x:Class="CalendarListTest.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<ItemsControl x:Name="calendarList">
<ItemsControl.ItemTemplate>
<DataTemplate>
<Calendar DisplayDate="{Binding CurrentDate}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</Grid>
** The place where the collection is assigned to the ItemsSource**
private void Window_Loaded( object sender, RoutedEventArgs e )
{
CalendarList list = new CalendarList( );
list.Add( new CalendarMonth( ) { CurrentDate = DateTime.Parse( "1.1.1979" ) } );
list.Add( new CalendarMonth( ) { CurrentDate = DateTime.Parse( "1.2.1979" ) } );
list.Add( new CalendarMonth( ) { CurrentDate = DateTime.Parse( "1.3.1979" ) } );
calendarList.ItemsSource = list;
}
The CalendarMonth ViewModel:
public class CalendarMonth
{
private DateTime _currentDate;
public DateTime CurrentDate
{
get { return _currentDate; }
set { _currentDate = value; }
}
}
And the Collection to bind to the ItemsControl:
public class CalendarList : ObservableCollection<CalendarMonth>
{
}
Now, the result:
Why is this happening?
edit: When providing <Calendar DisplayDate="{Binding CurrentDate, Mode=OneWay}" />
the binding works.
