Cannot find Datacontext (Viewdefinitions)

[Vikas]

I am having problem in binding to the Datacontext at viewdefinition level, It works if i create my viewmodel in xaml and set the DataContext of the grid using staticresource, but if i set the datacontext to the window in code behind it does not work

            <schedule:RadScheduleView.ViewDefinitions>
                <schedule:DayViewDefinition GroupFilter="{Binding GroupFilter2}"/>
                <schedule:WeekViewDefinition GroupFilter="{Binding GroupFilter2}"/>
                <schedule:MonthViewDefinition GroupFilter="{Binding GroupFilter2}"/>
            </schedule:RadScheduleView.ViewDefinitions>

----------- this does not work, does no bind to Group Filter -----------------
public MainWindow()
        {
            InitializeComponent();
            this.DataContext = new ViewModel();
        }


----------- this works -------------------

<Window.Resources>
        <local:ViewModel x:Key="ViewModel" AppointmentsSource="/Schedule;component/Appointments.xaml" />
<Grid x:Name="mainGrid" DataContext="{StaticResource ViewModel">

Hi Vikas,

In order to get the binding working correctly you would need to either set the DataContext in XAML or above the InitializeComponent in the constructor of the MainWindow:

public MainWindow()
{
    this.DataContext = new ViewModel();
    InitializeComponent();
}

Hope this helps.
