• Adorning a non-DependencyObject with a DependencyProperty

  - by Rob

  I'm trying to bind to a WinForms control's DataSource property in my WPF application but I'm not having much luck... Falafel.com gives it a shot, but although it claimes that a DependencyObject is not required to perform the binding, that seems to be the only way of doing it. Has anyone done this before?

• Is INotifyPropertyChanged only for the presentation layer?

  - by D.H.

  The INotifyPropertyChanged is obviously very useful in the view model for data binding to the view. Should I also use this interface in other parts of my application (e.g. in the business layer) when I want notifications of property changes, or I am better off using other notification mechanisms? I realize that there is nothing stopping me from using it, but are there any reasons that I shouldn't?

• Getting IBindingList Property to sort by

  - by Josh

  I've got a class called DatagridBoundList that implements CollectionBase and IBindingList. The implementation of IBindingList.ApplySort looks like this so far: void IBindingList.ApplySort(PropertyDescriptor property, ListSortDirection direction) { throw new NotSupportedException(); } I'm binding the DatagridBoundList to a DataGridView (winforms). When I reflect over the property parameter, I can't seem to find the name of the actual property that the list needs to be sorted by. What's the trick to finding out the name of the property to sort by?

• Is there anyway to stop automatic DataContext inheritance in Silverlight?

  - by Ant

  Is there anyway to stop automatic DataContext inheritance in Silverlight? I Set my DataContext on my parent UserControl in code. As a result all the xaml bindings inside the UserControl try to bind to the new DataConext they get (through the automatic DataContext Inheritance). The DataContext's for the children elements (actually they are children of children of children) of the UserControl is something I need to set in the UserControl's code... I don't want them being all smart because they end up binding to the wrong data object! :-)

• Is it okay to mix session data with form and querystring values in a custom model binder?

  - by Byron Sommardahl

  Working on a custom model binder in ASP.NET MVC 2. Most of the time I am binding data from typical form or querystring data. There are times that I end up letting the model binder bind part of an object and get the rest out of session at the controller action level. Does it make better sense to bind the entire object from the model binder (e.g. querystring, form, and session)?
