It is difficult to Debug the XAML data binding in WPF.
As a developer, we always tend to debug our programs when there are problems.
If something goes wrong like:
- No Data display
- Showing some wrong data
You need to debug and see:
- Whether the binding is successful
- Does data object have values
- and so on...
Here is the Trick to Debug the Data Binding of XAML.
All you need to do is create a
Converter
class.
Example:
public class DebugConverter : IValueConverter
{
#region IValueConverter Members
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value;
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
return value;
}
#endregion
}
While binding the Data to the Control, use the
DebugConverter
as
Converter
.
Like, declaring the
Converter
in XAML:
<Window.Resources>
<conv:DebugConverter x:Key="debugConverter" />
</Window.Resources>
Assigning to the Control whether we need to Debug the
DataBinding
:
<ListBox ItemsSource="{Binding ElementName=windowObject, Path=CollectionOfString, Converter={StaticResource debugConverter}}"/>
Now place a Breakpoint at the
Convert
function. That's it.
