Question

I have a .xaml file which has a listview. Listview has 2 items inside which are bind in a following way:

<ListView  Name="listView" ItemsSource="{Binding DeviceList}" SelectedItem="{Binding ConnectedDevice, Mode=TwoWay}" >
        <ListView.View>
            <GridView>
                <GridViewColumn Width="300" Header="Name" DisplayMemberBinding="{Binding Description}" />
                <GridViewColumn Width="240" Header="Connection Status" DisplayMemberBinding="{Binding DeviceName}" />
            </GridView>
        </ListView.View>
    </ListView>

Both Description and Devicename are part of ModelClass.In My ViewModel class I am able to extract the Device name as well as Description from the hardware I have connected.

    public ObservableCollection<ComDeviceInfo> DeviceList
    {
        get { return comDevices; }
        set
        {
            comDevices = value;
            NotifyPropertyChanged("DeviceList");
        }
    }

    public ComDeviceInfo ConnectedDevice
    {
        get { return connectedDevice; }
        set
        {
            connectedDevice = value;
            NotifyPropertyChanged("ConnectedDevice");
        }
    }        

    //Called Inside Constructor
    private void checkForDevicesTimer_Elapsed(Object source, ElapsedEventArgs e)
    {            
        DeviceList = ComDeviceManagement.FindDevices();            
    }

Here ComDeviceManagement is my class which has FINDDevices() which returns me the devicename and description. U can notice DeviceList = ComDeviceManagement.FindDevices() above which indicates both the descrip and name are present inside the list.

Everything is working fine. But What I basically want is to display both the Devicename and Description in One Column rather than two separate columns. Well the problem I am facing here is with Devicename and Description. Even though they both display different values, Isn’t their a way where I can concatinate them and display both the values into a single Column??? You may notice another column in .xaml file but I want to display(concatenate) both these inside my single column in listView.
How can i do that?

Please help!!

Answer 1

Two approaches

In the ComDeviceInfo class just add a property that concatenates

  public string DescName 
  {
      get 
      {
           return Description + " " + Name;
      }
  {

<GridViewColumn Width="300" Header="Name" DisplayMemberBinding="{Binding DescName}" />

Or use a multi-value converter

MultiBinding.Converter
