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...

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...

Somehow the Text property of the text box defined in the item template gets disconnected from the binding and stops being updated when the selected item changes.

I found a lot of posts that dodge this topic, but none that actually addresses this case. I have a ComboBox bound to a List<State>, where State is a business object that has Abbreviation and Name properties: this._stateComboBox.DataSource = ((Address)this._addressBindingSource.DataSource).States; this._stateComboBox.DisplayMember = "Ab...
