Binding to the current object or to its GetType method

Question

 Hello,

I have a collection of objects which is displayed by a component (the WPF Toolkit DataGrid).
Some properties of these objects are directly displayed but a column must contain a string derived from each object's type.

So the first solution would be to bind the column to the object itself and to add a value converter that would produce the good string.
1) How to bind directly to the object and not to one of its properties ?

Another solution would be to bind to the "GetType" method instead of a property and also add a converter that would convert the result of "GetType" to the good format.
2) Is it possible to bind to a method ?

Thanks by advance.

Answer 1

Just call {Binding}.  Don't use {Binding PropertyName} or {Binding Path=PropertyName}.  Just {Binding}.

Thanks a lot, that's perfect.

<UserControl x:Class="Test.Control1"
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:wpftk="http://schemas.microsoft.com/wpf/2008/toolkit" 
	xmlns:local="clr-namespace:Test" 
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
	<UserControl.Resources>
		<local:Converter x:Key="converter" />
	</UserControl.Resources>
	<wpftk:DataGrid
	  x:Name="grid"
	  ItemsSource="{Binding Path=Items}"
	  IsReadOnly="True"
	  AutoGenerateColumns="False">
		<wpftk:DataGrid.Columns>
			<wpftk:DataGridTextColumn Header="Field1" Binding="{Binding Path=Field1}" Width="Auto" />
			<wpftk:DataGridTextColumn Header="Field2" Width="Auto" Binding="{Binding Converter={StaticResource converter}}" />
		</wpftk:DataGrid.Columns>
	</wpftk:DataGrid>
</UserControl>

Answer 3

You are right in most of the cases. But this won't work if the ToString()  method of the bound object has been overriden.
