binding to the ToString() method in a DataTemplate
Is there any easy way to bind to the ToString() method in a DataTemplate? I would expect the Text property of a TextBlock to use ToString() by default for its Text property, but that does not happen. So any easy way to do this:
<DataTemplate x:Key="myTemplate">
<TextBlock Text="{Binding ToString()}"/>
<DataTemplate>
You can use Text="{Binding}" . The ToString() method is invoked implicitly.
you can use a Converter. like this:
public class PropertyValueStringConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value.ToString();
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotImplementedException();
}
}
Unfortunately, you cant bind control to method but you can circumvent to do that look:
public string GetText()
{
return "I am happy";
}
public string MyText
{
get { return GetText(); }
}
Now in XAML:
<DataTemplate x:Key="myTemplate">
<TextBlock Text="{Binding MyText}"/>
<DataTemplate>
be careful MyText property must be in the context of the window.
