所以这是我的基础课程,我的目的是用来填充列表。我基本上有一组DAC(或DAC的其他衍生物),我在组合框中列出。 组合框填充
combobox1.SetBinding(ComboBox.ItemsSourceProperty, new Binding() { Source = cdacList });
combobox1.DisplayMemberPath = "Name";
当用户选择其中一个项目时,应根据从组合框中选择的索引更新文本框和滑块的值,并使用该索引访问数组中的数据。
我尝试直接绑定
textbox1.SetBinding(TextBox.TextProperty, new Binding("Address") { Source = cdacList[combobox1.SelectedIndex] });
slider1.SetBinding(Slider.ValueProperty, new Binding("Value") { Source = cdacList[combobox1.SelectedIndex] });
但它不会自我更新。我知道我需要通过绑定来获得其他方面,但我不能自己解决这个问题。
答案 0 :(得分:0)
您应该能够设置一次如下所示的绑定,而无需在以后更改它们:
textbox1.SetBinding(TextBox.TextProperty,
new Binding("SelectedItem.Address") { Source = combobox1 });
slider1.SetBinding(Slider.ValueProperty,
new Binding("SelectedItem.Value") { Source = combobox1 });
也就是说,绑定应该在XAML中创建:
<TextBox x:Name="textbox1"
Text="{Binding SelectedItem.Address, ElementName=combobox1}" .../>
<Sliderx:Name="slider1"
Text="{Binding SelectedItem.Value, ElementName=combobox1}" .../>
