Use Dot(.)
as binding property path separator not Forward slash(/)
<Label FontWeight="Bold" FontSize="40"
Content="{Binding MyDataObject.AnotherSubObject.MyProperty}"/>
Вопрос
I am trying to bind a label to an Object.Object.Property and I don't get it run.
Here is my code:
XAML
<Window x:Class="MyApp.MyWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MyWindow" Height="1120" Width="800">
<Grid Name="MyGrid">
<StackPanel Orientation="Horizontal">
<Label FontWeight="Bold" FontSize="40" Content="{Binding MyDataObject/AnotherSubObject/MyProperty}"/>
</StackPanel>
</Grid>
</Window>
And the Code:
public partial class MyWindow : Window
{
public MySubObject MyDataObject { get; set; }
public MyWindow(MySubObject object)
{
InitializeComponent();
this.MyDataObject = object; // Contains MyDataObject.AnotherObject.MyProperty
DataContext = this;
}
}
And the code for MySubObject object looks like this:
public class MySubObject : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
AnotherObject _AnotherObject;
public MySubObject()
{
this._AnotherObject = new AnotherObject();
this._AnotherObject.Property = "Some Value";
}
public AnotherObject AnotherObject
{
get { return _AnotherObject; }
set { _AnotherObject = value; OnPropertyChanged("AnotherObject"); }
}
// Create the OnPropertyChanged method to raise the event
protected void OnPropertyChanged(string name)
{
PropertyChangedEventHandler handler = PropertyChanged;
if (handler != null)
{
handler(this, new PropertyChangedEventArgs(name));
}
}
}
I would be glad to get dome support for this case.
