How to Bind on a Property by String as Propertyname - wpf

Question

Hi i want to Bind to an "unknown" (i only get a string) Property in Xaml
at first i wrote an IValueConverter but you can't bind to ConverterParameter
so i rewrite it as IMultiValueConverter but now i'm unable to figure out how to use the <Binding /> with out Path
or my i'm wrong?
if you write <TextBlock Text="{Binding}" /> you will get the object Person
and with {Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}, Path=View.Columns[0].Header}} i'm able to access the Header Text of the first row
now i'm only need to combine both and a will get the Property right?
my test Xaml code:
<UserControl x:Class="Frameworktest.View.auswahl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Frameworktest">
<UserControl.Resources>
<local:toPropertyConverter x:Key="PropertyConverter"/>
</UserControl.Resources>
<StackPanel>
<!--...-->
<Border BorderThickness="5" HorizontalAlignment="Left" VerticalAlignment="Top"
BorderBrush="Green" CornerRadius="5">
<ListView Name="listView1" IsSynchronizedWithCurrentItem="False"
ItemsSource="{Binding Items, UpdateSourceTrigger=PropertyChanged}" <!--ObservableCollection<Person>-->
SelectedItem="{Binding selectedItem, UpdateSourceTrigger=PropertyChanged}">
<ListView.View>
<GridView>
<GridViewColumn Header="Name">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Margin="1">
<TextBlock.Text>
<MultiBinding Converter="{StaticResource PropertyConverter}">
<Binding /><!-- How do i {Binding} here?-->
<Binding Source="{Binding RelativeSource={Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}, Path=View.Columns[0].Header}}" />
</MultiBinding>
</TextBlock.Text>
</TextBlock>
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Firstname" >
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Margin="1" Text="{Binding Path=Name}" Width="100"/><!--works-->
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
<GridViewColumn Header="Age">
<GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Margin="1" Text="{Binding Age}" Width="50"/><!--works-->
</DataTemplate>
</GridViewColumn.CellTemplate>
</GridViewColumn>
</GridView>
</ListView.View>
</ListView>
</Border>
</StackPanel>
</UserControl>
the Converter:
public class toPropertyConverter : IMultiValueConverter
{
public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
return values[0].GetType().GetProperty((string)values[1]);
}
public object[] ConvertBack(object value, Type[] targetTypes, object parameter, CultureInfo culture)
{
throw new NotImplementedException();
}
}
The Model
public class Person : MBase, IContains
{
private string _name;
public string Name
{
get { return _name; }
set { _name = value;
RaisePropertyChanged(() => Reg(() => Name));
}
}
private string _firstname;
public string Firstname
{
get { return _firstname; }
set
{
_firstname = value;
RaisePropertyChanged(() => Reg(() => Firstname));
}
}
private int _age;
public int Age
{
get { return _age; }
set
{
_age = value;
RaisePropertyChanged(() => Reg(() => Age));
}
}
public bool Contains(string text)
{
string pers = string.Format("{0} {1}", Firstname, Name);
return pers.Contains(text);
}
}
Update my current Multibindung
<MultiBinding Converter="{StaticResource PropertyConverter}">
<Binding Path="."/>
<Binding RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType={x:Type ListView}}" Path="View.Columns[0].Header}}" /> <!-- doesn't contain the word "Name" like i suspected -->
</MultiBinding>
LAST Update
it is a dead end in my case you can't Bind from the GridViewColumn.CellTemplate to the specific Column Header Value

Answer 1

{Binding} implicitely means : {Binding Path=.}.
So you could use
<Binding Path="."/>
