RibbonComboBox Text Not Retaining Edits

Question

I have the following xaml in my ui:

<ribbon:RibbonGallery SelectedValue="{Binding Text}"
                      SelectedValuePath="Content"
                      SelectedItem="{Binding SelectedRemark, Mode=TwoWay}"
                      MaxColumnCount="1">
    <ribbon:RibbonGalleryCategory ItemsSource="{Binding Remarks}" DisplayMemberPath="Text"/>
</ribbon:RibbonGallery>

Both SelectedRemark and Remarks are properties on my view model; and Remarks is an ObservableCollection<Remark>.

It will display properly, and I can edit the text in the combobox. However, as soon as the combobox loses focus, it reverts back to whatever the the original text was.

I'm new to WPF, and cannot figure out what am I doing wrong.

Answer 1

Those bindings are all related to selection. I'm not certain how the Ribbon operates but it doesn't appear that what you are trying to do will give you the results you are after.

In addition the ObservableCollection<Remark> is only relative from an Add/Remove stance when making use of binding. It will not propagate changes to the items within the collection. If you were wanting that functionality you will need to implement INotifyPropertyChanged on the Remark object, then raise a property changed notification as needed.
