Winform birlikte çalışabilirlik için bir açılan liste oluşturmak için çalışıyorum, ve kod açılan yapıyorum. Ancak, bir sorun bağlamak için veri alma DataTemplate dayalı belirtmek yaşıyorum.

Neyi kaçırıyorum?

drpCreditCardNumberWpf = new ComboBox();  
DataTemplate cardLayout = new DataTemplate {DataType = typeof (CreditCardPayment)};   
StackPanel sp = new StackPanel
{
    Orientation = System.Windows.Controls.Orientation.Vertical
};   

TextBlock cardHolder = new TextBlock {ToolTip = "Card Holder Name"};
cardHolder.SetBinding(TextBlock.TextProperty, "BillToName");
sp.Children.Add(cardHolder);

TextBlock cardNumber = new TextBlock {ToolTip = "Credit Card Number"};
cardNumber.SetBinding(TextBlock.TextProperty, "SafeNumber");
sp.Children.Add(cardNumber);

TextBlock notes = new TextBlock {ToolTip = "Notes"};
notes.SetBinding(TextBlock.TextProperty, "Notes");
sp.Children.Add(notes);

cardLayout.Resources.Add(sp, null);

drpCreditCardNumberWpf.ItemTemplate = cardLayout;

Zaten drpCreditCardNumberWpf... ItemsSource vb ayarladığınızı varsayarak

//create the data template
DataTemplate cardLayout = new DataTemplate();
cardLayout.DataType = typeof(CreditCardPayment);

//set up the stack panel
FrameworkElementFactory spFactory = new FrameworkElementFactory(typeof(StackPanel));
spFactory.Name = "myComboFactory";
spFactory.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);

//set up the card holder textblock
FrameworkElementFactory cardHolder = new FrameworkElementFactory(typeof(TextBlock));
cardHolder.SetBinding(TextBlock.TextProperty, new Binding("BillToName"));
cardHolder.SetValue(TextBlock.ToolTipProperty, "Card Holder Name");
spFactory.AppendChild(cardHolder);

//set up the card number textblock
FrameworkElementFactory cardNumber = new FrameworkElementFactory(typeof(TextBlock));
cardNumber.SetBinding(TextBlock.TextProperty, new Binding("SafeNumber"));
cardNumber.SetValue(TextBlock.ToolTipProperty, "Credit Card Number");
spFactory.AppendChild(cardNumber);

//set up the notes textblock
FrameworkElementFactory notes = new FrameworkElementFactory(typeof(TextBlock));
notes.SetBinding(TextBlock.TextProperty, new Binding("Notes"));
notes.SetValue(TextBlock.ToolTipProperty, "Notes");
spFactory.AppendChild(notes);

//set the visual tree of the data template
cardLayout.VisualTree = spFactory;

//set the item template to be our shiny new data template
drpCreditCardNumberWpf.ItemTemplate = cardLayout;

Kenar boşlukları gibi diğer özelliklerini ayarlamak için TextBlocks ToolTip set var, aynı şekilde kullanabilirsiniz.
