Thank you. But there is no SelectedItems avaliable in Intellicense in xaml for XamComboBoxEditor.

Is SelectedItems a dependency property and available for binding? 

For example, entity is Department(deptid, deptName,,,)., SelectedDepartment is property in ViewModel. xaml like:

SelectedItem="{Binding SelectedDepartment, Mode=TwoWay}"
DisplayMemberPath="DeptName"

Then from the binding, I want to get the selected ID result, like (1,2,....)

SelectedDepartment is bound to SelectedItem, not SelectedItems.
With this kind of binding, how can I get SelectedItems in ViewModel?

Like the native ListBox control, the xamComboEditors SelectedItems property is readonly and not a dependency property.

I've attached an example of how you can pseudo-bind the SelectedItems property using a Behavior.

Hi Devin,

I tried this behavior but it doesn't work in two-way mode. If I add items to the bound selected items collection from my view model, it does not get reflected in the XamComboEditor.

Could you please help.

Thanks,

Hi,

Any updates on this? Could you please take this on priority?

Thanks,

Hi I have done this long time ago. Here is my solution for multiple selection binding with that behavior in place:

<ig:XamComboEditor x:Name="EAComboBox" AllowMultipleSelection="True" CheckBoxVisibility="Visible"
    ItemsSource="{Binding MyListenItems, Mode=TwoWay}"
    DisplayMemberPath="ItemName"    
    SelectedItem="{Binding SelectedItem, Mode=TwoWay}"  
    IsEditable="False"
    Loaded="EAComboBox_Loaded">
    <i:Interaction.Behaviors>
        <Common:XamComboEditorSelectedItemsBehavior x:Name="cbbehavior" SelectedItems="{Binding SelectedItems, Mode=TwoWay}" />
    </i:Interaction.Behaviors>
</ig:XamComboEditor>


      private void EAComboBox_Loaded(object sender, RoutedEventArgs e)
        {
            XamComboEditorSelectedItemsBehavior be = this.FindName("cbbehavior") as XamComboEditorSelectedItemsBehavior;
            MyVM vm = this.DataContext as MyVM;
            var temp = new ObservableCollection<MyItem>();
            Transfer(vm.SelectedItems, temp);
            vm.SelectedItems.Clear();
            Transfer(temp, vm.SelectedItems);
            vm.Reset();
        }

        private void Transfer(IList source, IList target)
        {
            if (source == null || target == null)
                return;
            target.Clear();
            foreach (var o in source)
            {
                target.Add(o);
            }
        }

Good luck!
