In a simple form, I bind to a number of different objects -- some go in listboxes; some in textblocks. A couple of these objects have collaborating objects upon which the ToString() method calls when doing its work -- typically a formatter of some kind. When I step through the code I see that when the databinding is being set up, To...
I found an example online that explains how to perform databinding to a ListBox control using LINQ in WPF. The example works fine but when I replicate the same code in Silverlight it doesn't work. Is there a fundamental difference between Silverlight and WPF that I'm not aware of? Here is an Example of the XAML: <ListBox x:Name="list...
This started with weird behaviour that I thought was tied to my implementation of ToString(), and I asked this question: http://stackoverflow.com/questions/2916068/why-wont-wpf-databindings-show-text-when-tostring-has-a-collaborating-object It turns out to have nothing to do with collaborators and is reproducible. When I bind Label.Con...

JFace Databinding doesn't support generics, so it isn't particularly type-safe. And apparently it never will, since they wish to preserve Java 1.3 support. JGoodies supports generics since 2.0.0. Has anyone ported JGoodies 2 to SWT/JFace? Or is there another library which allows both? ...
I'm using the following syntax to bind to a div element: <div id="previewdiv"><%=Preview%></div> Where Preview is a property on my page.

On the server side, I'm able to reference the new page via this property but for some reason when the page is pos...
