You're saying that the DataTemplate to display a GeneralMcmMessage
is to instantiate new GeneralMcmMessage
.
<DataTemplate DataType="local:GeneralMcmMessage">
<local:GeneralMcmMessage />
</DataTemplate>
I'd recommend instead of making a collection of your UserControl to make a collection of your model object instead, and bind to the properties within that within your UserControl.
Either way though - the object you created in code will be the DataContext for the one you created in XAML so removing the ElementName=_this
should bind appropriately. Try this simplified XAML in your UserControl instead.
<StackPanel VerticalAlignment="Stretch" Orientation="Horizontal" Grid.Row="0">
<TextBlock Name="MessageDateTime" Text="{Binding TimeStamp, StringFormat=MM/dd/yyyy h:mm:ss.fff tt \'GMT\' (zzz)}" />
<TextBlock Name="MessageTypeLabel" Margin="15,0,5,0" Text="Type:"/>
<TextBlock Name="MessageType" Text="{Binding Type}" />
</StackPanel>
<StackPanel VerticalAlignment="Stretch" Orientation="Horizontal" Grid.Row="1">
<TextBlock Name="MessageNameLabel" Margin="0,0,5,0" Text="Message Name:" />
<TextBlock Name="MessageNameValue" Text="{Binding MessageName}" TextWrapping="Wrap" />
</StackPanel>
<StackPanel VerticalAlignment="Stretch" Orientation="Vertical" Grid.Row="2">
<TextBlock Name="MessageLabel" Text="Message:"/>
<TextBlock Name="Message" Margin="10,0,0,0" Text="{Binding MessageContent}" />
</StackPanel>
