I'm encountering a problem with the RadComboBox, where the items are not updating when the corresponding binding is changed.
Below is the sample code I'm using that illustrates the problem for me (using Telerik Silverlight RadControls from Dec 20 2011):
- Select "Three" in the combo box
- Click the button above it
The button click changes the name of the 3rd data item and raises a property change for both the Items collection and SelectedItem property on the view model.
I would expect this to rebind the items source and update the selected item to reflect the name, but this does not happen - the drop down items do not reflect the item name change at all.
Also, the selected item name does not change until I click the dropdown then click outside the control, which is not the desired behaviour.
Is there a way to work around these problems?
Thanks for your help,
