Hey, I was wondering if there was a way of calling a method or updating a property on my ViewModel object when WPF binds to the object ? The reason I want to do this is that when my viewModel objects get created their data model only contains an ID that is used to query data from the database when necessary. So when the user navigates t...

Hi, Do you know any example of how to animate the insertion of an item on a ListBox? The effect I was thinking of is something like: At first we have items A and B on the ListBox. Than a C item is inserted between A and B. In the effect I imagined, before C is inserted, A and B become gradually more distant until a C element fits in ...
Hi, I need to do a conceptually simple thing: Call a remote method from a WPF application to the server. But I need to share the model types with both sides.. I mean, I need to send a Person object as parameter from the client and also receive objects of the same type. What's the best way? Is it to use WCF? Is there a better way? Do y...
It's "easy"! I just came across this blog post by Rudi Grobler that says it's "easy" to port a theme from Silverlight to WPF. Unfortunately, he doesn't say how to do it. Download and install I have installed both the WPF Toolkit and Silverlight Toolkit from Codeplex. I also went and dug up the source code for the theme I'm interest...

I have an expander that has n contained elements (possibly other Expanders that also contain elements). Now I want to programmatically bring a contained element into view - like with BringIntoView() for ScrollViewers. All Expanders that currently hide the element should expand. My current idea is to subclass the Expander and make it ...
I'm trying to convert my VB project to WPF, and one big problem I'm having is what to do about a large GridView that contains in each cell a single image. The grid needs to be very large so is the best way to do this in WPF a datagrid, or a dynamically generated Grid control, or something else? I'm not sure which controls give the best p...

In my WPF MVVM application my model is a complex tree of Model objects wich constantly changes at runtime. Model instances come and go at runtime, change their position within the tree and of course change their many properties. My View is almost a one-to-one visual representation of that tree. Every Model instance is in 80% of the cases...
