CheckComboBox Help

[sup3r93]

HI, I'm trying to use the CheckComboBox control, I take the data from an XML file, which is present in a folder on the computer, to be exact "C:\Emergency\Configuration\Configuration.xml" I used xmlDocument to import the file , and then through a foreach I added the various items, but I have two problems.

1) If I select only one item it is not shown 2) If I select two elements they are shown, but if I deselect them, the last deselected element is also shown 3) Question: How can I get the values pressed on 2 or more different strings?

Thank you so much :)

XAML CODE

<xctk:CheckComboBox Grid.Column="1" Grid.Row="4" x:Name="ComboCirculation01" Height="30" Width="200" HorizontalAlignment="Center" VerticalAlignment="Center" DisplayMemberPath="Color" ValueMemberPath="Level" SelectedValue="{Binding SelectedValue}" SelectedItemsOverride="{Binding SelectedItems}"/>

CS CODE

` #region Circulation

    public class CirculationItem {
        public string Circulation { get; set; }
        public bool IsSelected { get; set; }
    }

    private void CirculationData() {
        string configFile = @"C:\Emergenza\Configuration\Configuration.xml";

        XmlDocument xmlDocument = new XmlDocument();
        xmlDocument.Load(configFile);

        XmlNodeList nodes = xmlDocument.SelectNodes("/Config/Paziente/Associazione/Circolo/Value");

        ComboCirculation01.DisplayMemberPath = "Circulation"; 

        List<CirculationItem> circulationItems = new List<CirculationItem>();

        foreach (XmlNode node in nodes) {
            string circulation = node.InnerText;
            circulationItems.Add(new CirculationItem { Circulation = circulation });
        }

        ComboCirculation01.ItemsSource = circulationItems;
        ComboCirculation01.ItemSelectionChanged += ComboCirculation01_ItemSelectionChanged;
    }

    private void ComboCirculation01_ItemSelectionChanged(object sender, Xceed.Wpf.Toolkit.Primitives.ItemSelectionChangedEventArgs e) {
        foreach (CirculationItem item in ComboCirculation01.Items) {
            item.IsSelected = ComboCirculation01.SelectedItems.Contains(item);
        }
    }

In the xaml, you set ValueMemberPath to "Level", which is not a property on your Circulation class.

I'm not sure why it's having this weird behavior in this invalid usage, but I instead tried ValueMemberPath="Circulation" (given your example), and I then get a proper behavior.

Thanks, Dan

@XceedDanP I apologize if I reopened the topic, but I wanted to avoid opening another one in case I made a mistake I apologize, is it possible with your control to perform this operation?

If I select option "A" all the other options are disabled, if instead I select option "B" options "A" and "C" are disabled
