If you want the full control, you can use the Explicit value and then do the updates manually, but this does take a bit of the fun out of working with data bindings. The text field is updated when SelectedObject is changed on the grid. I am sure this is unrelated, but I found it interesting. This behavior is controlled by a property on the binding called UpdateSourceTrigger. Posted on Aug 27 ivan 5, posts I've not been able to reproduce this. It might be affected by the Style or by the exact composition of the ItemsSource, depending on the type of the property. The first one is set to Explicit, which basically means that the source won't be updated unless you manually do it. However, since WPF is pretty good at controlling this for you, the default value should suffice for most cases, where you will get the best mix of a constantly updated UI and good performance. Instead, the source was updated only after focus was lost on the TextBox. There are intermittent selection problems. For those situations where you need more control of the process, this property will definitely help though. For that reason, I have added a button next to the TextBox, which will update the source value on demand.
