Hi,
I have a collection of items. It is bound to two different comboboxes. Is it possible to hide some items in one of the comboboxes?
I tried smth like
<telerik:RadComboBox>
<telerik:RadComboBox.ItemContainerStyle>
                    <Style TargetType="telerik:RadComboBoxItem">
                        <Setter Property="Visibility" Value="{Binding SomeBooleanProperty, Converter={StaticResource BooleanToVisibilityConverter}}"/>
                    </Style>
                </telerik:RadComboBox.ItemContainerStyle>
</telerik:RadComboBox>

But it didn't work out.
Any directions?

Best Regards,
Juliana

Hello Juliana,

I had similar problem a couple of days ago. This post helped me solve it: How to enable/disable specific items in RadComboBox.

Long story short. Just make your custom ItemTemplate for RadComboBox:

<telerik:RadComboBox.ItemTemplate>

    <DataTemplate>

        <telerik:ContainerBinding.ContainerBindings>

            <telerik:ContainerBindingCollection>

                <telerik:ContainerBinding PropertyName="Visibility" Binding="{Binding Enabled, Mode=OneWay, Converter={StaticResource BooleanToVisibilityConverter}}" />

            </telerik:ContainerBindingCollection>

        </telerik:ContainerBinding.ContainerBindings>

        <TextBlock Text="{Binding DisplayProperty, Mode=OneWay}" />

    </DataTemplate>

</telerik:RadComboBox.ItemTemplate>

And don't forget to set for proper display RadComboBox settings to (it's replacement for 'DisplayMemeberPath' which does not work with custom item templates):

telerik:TextSearch.TextPath="DisplayProperty"

I hope this solution will help you too. :)

Best Regards,
Dragana
