WPF pass parent binding object to the converter
I have ItemsControl that is bound to collection of type Student. Inside the ItemTemplate I have a TextBox that uses IValueConverter to do some custom calculations and logic. I want to pass the actual Student object to the value converter, instead a property of it. How can I do that? Here's a sample of my code.
<ItemsControl ItemsSource="{Binding StudentList}">
<ItemsControl.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name}" />
<TextBlock Text="{Binding ????, Converter={StaticResource MyConverter}}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
In the code I have this
public class MyValueConverter : IValueConverter
{
public object Convert(object value, Type targetType, object 开发者_StackOverflowparameter, System.Globalization.CultureInfo culture)
{
// I want 'value' to be of type Student.
return null;
}
}
You can just leave out the path. That way you get at the actual object bound to.
<TextBlock Text="{Binding Converter={StaticResource MyConverter}}"/>
or if you want to be explicit about it:
<TextBlock Text="{Binding Path=., Converter={StaticResource MyConverter}}"/>
