How to populate a ComboBox in XAML
提问by Sonhja
I'm trying to populate a ComboBoxwith a pair of String, Value. I did it in code behind like this:
我正在尝试ComboBox用一对String, Value填充 a 。我在后面的代码中这样做了：
listCombos = new List<ComboBoxItem>();
item = new ComboBoxItem { Text = Cultures.Resources.Off, Value = "Off" };
listCombos.Add(item);
item = new ComboBoxItem { Text = Cultures.Resources.Low, Value = "Low" };
listCombos.Add(item);
item = new ComboBoxItem { Text = Cultures.Resources.Medium, Value = "Medium" };
listCombos.Add(item);
item = new ComboBoxItem { Text = Cultures.Resources.High, Value = "High" };
listCombos.Add(item);
combo.ItemsSource = listCombos;
ComboBoxItem:
组合框项目：
public class ComboBoxItem
{
public string Text { get; set; }
public object Value { get; set; }
public override string ToString()
{
return Text;
}
}
As you can see, I'm inserting the Textvalue using my ResourceDictionary. But if I do it in this way, when I change language at runtime, the ComboBoxcontent doesn't.
如您所见，我正在Text使用我的ResourceDictionary. 但是如果我这样做，当我在运行时更改语言时，ComboBox内容不会。
So I wanted to try to fill my ComboBoxat the design (at XAML).
所以我想尝试填补我ComboBox的设计（在 XAML）。
So my question is: how can I fill my ComboBoxwith a pair Text, Valuelike above?
所以我的问题是：如何ComboBox用上面的一对Text, Value填充我的？

You will use Tag, not Valuein xaml.
This would be like this:
您将使用Tag, 而不是Value在 xaml 中。这将是这样的：
<ComboBox>
<ComboBoxItem Tag="L" IsSelected="True">Low</ComboBoxItem>
<ComboBoxItem Tag="H">High</ComboBoxItem>
<ComboBoxItem Tag="M">Medium</ComboBoxItem>
</ComboBox>
