Ribbon and editable ComboBox with DataTemplate problem
I have different problems with simple List<string> binding to a ComboBox inside a Ribbon.
When using a combination of IsEditable and DataTemplate, it throws System.Runtime.InteropServices.COMException:
<ribbon:RibbonComboBox
IsEditable="True"
IsTextSearchEnabled="True"
DisplayOptions="Normal,Simplified"
ItemsSource="{Binding ViewModel.FontNames, ElementName=MainPagePage}"
SelectedValue="{Binding ViewModel.SelectedFontFamilyName, Mode=TwoWay, ElementName=MainPagePage}">
<ribbon:RibbonComboBox.ItemTemplate>
<DataTemplate>
<TextBlock FontFamily="{Binding}" Text="{Binding}" />
</DataTemplate>
</ribbon:RibbonComboBox.ItemTemplate>
</ribbon:RibbonComboBox>
(Using Binding instead of x:Bind because this ComboBox is inside a RibboinItemHost). Same behavior with SfComboBox.
Not using DataTemplate works but does not display the text of the items. Being a list of strings, dont know if DisplayMemberPath is needed (same with a list of floats for a font size combobox).
Also having problems when using a normal editable WinUI ComboBox inside a Ribbon:
Clicking the editable part does not allow to enter text. Have to show the dropdown and then enter the text.
But even worse, SelectedValue/Item does not change nor fire the binded property set. Outside the Ribbon it works as expected (vanilla WinUI, havent tried SF).
