I'll start out by saying that I'm trying to follow MVVM as strictly as I can, so I'd like to do the following using Binding only. I have multiple DataGrids showing different ObservableCollections of the same data type. How can I define once which columns, and their Binding paths, will show on all of the DataGrids? It doesn't appear tha...
I am trying to declaratively bind a ComboBox within a DataGrid CellEditingTemplate using a ViewModel. The ComboBox is not being bound. What am I doing wrong?

When binding a property to the 'SelectedItem' of a WPF Combobox, I would expect to see that property setter get called every time the combobox's selection is changed. I'm not seeing that. Should the Combobox be calling the bound 'SelectedItem's property setter when the selection is changed? Addition: I actually have the binding partiall...

New to Silverlight. I'm working on a chat application where new chat messages are added to the bottom of a list. I had a working version that used as StackPanel inside a ScrollViewer and then in some code behind used StackPanel.Children.Add().

I'm trying to bind a view model property to the 'SelectedItem' attribute of a WPF combobox. This combobox resides within a RowDetailsTemplate of a DataGrid. The binding is partially there because the view model's property getter and setter each get called once when a row is selected (And thus causes the details view to expand). However t...

Example: public class View...
