Question

I have a DataTemplate that is displaying objects with three fields, e.g.:

Name = 'Font Color' Value = 'Orange' Editable = 'True' 

but I want to display them as e.g.:

Font Color: Orange Editable

But I’m having trouble finding the syntax to use Triggers here in order to e.g. display ‘Editable’ when the field Editable=’True’

Does anyone know the syntax to do this?

The following code results in ‘Binding cannot be used in Property’:

<DataTemplate x:Key='settingsItemTemplate'>     <StackPanel Orientation='Horizontal'>         <Label Content='{Binding XPath=Name}' ContentStringFormat=' {0}:'/>         <Label Content='{Binding XPath=Value}'/>         <Label>             <Label.Triggers>                 <Trigger Property='{Binding XPath=Editable}' Value='True'>                     <Setter Property='Content' Value='Editable'/>                 </Trigger>                 <Trigger Property='{Binding XPath=Editable}' Value='False'>                     <Setter Property='Content' Value='NOT Editable'/>                 </Trigger>             </Label.Triggers>         </Label>     </StackPanel> </DataTemplate> 

Answer 1

Would it work to use a TextBlock instead of a Label? TextBlock does have a Text property that you should be able to bind to in this case.

If you really want to use a Label, another approach would be to create two DataTemplate‘s – one for the editable case, and another for non-editable. You can then bind the ContentTemplate property to the appropriate template.

Update: After looking into it some more, it looks like Trigger does not support binding for its Property attribute. However, DataTrigger does support this:

<StackPanel>     <CheckBox Name='EditableCheckBox'>Is Editable</CheckBox>     <Label>         <Label.Resources>             <Style TargetType='{x:Type Label}'>                 <Style.Triggers>                     <DataTrigger Binding='{Binding ElementName=EditableCheckBox, Path=IsChecked}' Value='True'>                         <Setter Property='Content' Value='Editable' />                     </DataTrigger>                     <DataTrigger Binding='{Binding ElementName=EditableCheckBox, Path=IsChecked}' Value='False'>                         <Setter Property='Content' Value='NOT Editable' />                     </DataTrigger>                 </Style.Triggers>             </Style>         </Label.Resources>     </Label> </StackPanel> 

You should be able to modify the Binding attribute to bind to your XML data source instead of do the value of another control.
