WPF: Changing a ComboBox's ItemTemplate removes the ability to jump down the list as you type. Any way to fix this?

Question

PersonVM.cs

public class MainWindowVM
{
    public MainWindowVM()
    {
        PersonList = new ObservableCollection(Employees);
    }

See my answer to this question: Can I do Text search with multibinding

Unfortunately TextSearch.Text doesn't work in a DataTemplate. I think you have two options here

Option 1. Set IsTextSearchEnabled to True for the ComboBox, override ToString in your source class and change the MultiBinding in the TextBlock to a Binding

    
        
            
        
    
 

public class Person
{
    public override string ToString()
    {
        return String.Format("{0} | {1}", Name, ID);
    }

    public string Name { get; set; }
    public int ID { get; set; }
}

Option 2. Make a new Property in your source class where you combine Name and ID for the TextSearch.TextPath. Also, you should call OnPropertyChanged for NameAndId whenever you do it for Name or ID

public string NameAndId
{
    return String.Format("{0} | {1}", Name, ID);
}
