我正在尝试为winform互操作构建下拉列表,并且正在代码中创建下拉列表。但是,我在根据我指定的DataTemplate绑定数据时遇到问题。
我想念什么?
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;
假设您已经ItemsSource为drpCreditCardNumberWpf… 设置了etc
ItemsSource
drpCreditCardNumberWpf
//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;
你可以使用我已经设置了同样的方式ToolTip在TextBlocks到集中的其他属性,如利润。
