Hi
Ok, this confuses me a bit, I can get it to work by not deriving from
ListView and setting all my settings in the initialize method and instead
having a listview member and assigning all the values on it. Can anyone see
a reason for this?
def BuildListView()
self.statusListView = ListView.new
self.statusListView.HorizontalAlignment = HorizontalAlignment.Stretch
self.statusListView.Margin = Thickness.new(0,5,0,5)
self.statusListView.Height = 200
textblock = FrameworkElementFactory.new(TextBlock.to_clr_type)
setter = Setter.new
setter.Property = TextBlock.FontSizeProperty
setter.Value = 14.0
dataTrigger = DataTrigger.new
dataTrigger.Binding = System::Windows::Data::Binding.new("messageType")
dataTrigger.Value = "Status"
dataTrigger.Setters.Add(setter)
style = Style.new(TextBlock.to_clr_type)
style.Triggers.Add(dataTrigger)
textblock.SetValue(TextBlock.StyleProperty, style)
textblock.SetBinding(TextBlock.TextProperty,
System::Windows::Data::Binding.new("message"))
template = DataTemplate.new
template.VisualTree = textblock
self.statusListView.ItemTemplate = template
end
