Combo and IValueconverter
posted

I have combo as

 <ig:XamComboEditor Name="YComboEditor"   ItemsSource="{Binding Path=YearsData}"  
            DisplayMemberPath="SomeYear"   
            SelectionChanged="YComboEditor_SelectionChanged"    
            SelectedItem="{Binding SomeYear,Mode=TwoWay,Converter={StaticResource YearConverter}}">

 </ig:XamComboEditor>

This is populated correctly

I have IvalueConverter which checkes for the year and then should return current year as selected

For some reason the IValueconverter is not triggered

Any ideas?

    Hi,

    in order for the ValueConverter to be triggered a valid binding should be used so the ValueConverter will have something to convert from/to. Is "SomeYear" valid binding target in your view model?

    Looking at your xaml I am get the impression(the path for your SelectedItem binding is the same as the DisplayMemeberPath string) that you are trying to bind to a property of an ItemSource's item. Generally you should bind SelectedItem to a valid binding target.

    You could check this sample which is showing how xamComboEditor is used with value converter in SelectedItem binding.
