Question
I want to a property to the current item of a ICollectionView
how can I do it? The ICollectionView
is used for binding to a combo box, how can I bind another control to the ICollectionView
's selected item?
Solution
Check out this cheat sheet. In particular, check out the /
binding symbol, which references the current item in a collection view.
OTHER TIPS
Setting IsSynchronizedWithCurrentItem on the ComboBox will update the current item with its selection (not sure if you're already doing this). You can then bind the same collection and access its current item with the binding:
<ComboBox ItemsSource="{Binding Names}" IsSynchronizedWithCurrentItem="True" />
<Button Content="{Binding Path=Names/}"/>
Give your ComboBox a name and bind to it's SelectedItem.
For example:
<ComboBox x:Name="MyComboBox" ItemsSource="{Binding MyList}" />
<Grid DataContext={Binding ElementName=MyComboBox, Path=SelectedItem>
...
</Grid>
