Wpf列表框文本但发送值 [英] Wpf listbox text but send value

问题描述

我被困住了。我有一个带有列表框的WPF页面，该列表框具有来自codebehind（.cs）文件的绑定值。显示的文本是Active，Pending，Discharged等。当我选择Active时，我需要得到字符串A。我该怎么做？



在XAML中

 DisplayMemberPath =ContentNameItemsSource ={Binding}SelectedValuePath =ContentCode> 

在CS

  public  PatientSearch（）
 {
 InitializeComponent（）; 
 
  var  data =  new  [] {
  new  ListBoxData {ContentCode =   A，ContentName =  有效}，
  new  ListBoxData {ContentCode =   P，ContentName =   待定}，
  new  ListBoxData {ContentCode =   D，ContentName =  放电}，
  new  ListBoxData {ContentCode =   I，ContentName =  中断}，
  new  ListBoxData {ContentCode =   X，ContentName =  已存档} 
}; 
  //  使用ListBox绑定数组列表 
 LbPatStat.ItemsSource = data; 
} 
 
  public   class  ListBoxData 
 {
  public   string  ContentCode { get  ;  set ; } 
  public   string  ContentName { get ;  set ; } 
} 
 

我的尝试：



我试图使用IF / Else和Switch语句，但每个语句都通过Active而不是A ...

解决方案

< blockquote>只需在ListBox SelectionChanged事件中执行以下操作，

  private   void  LbPatStat_SelectionChanged（ object  sender，SelectionChangedEventArgs e）
 {
 ListBoxData SelectedListBoxData =（ListBoxData）LbPatStat.SelectedItem; 
 MessageBox.Show（  SelectedListBoxData： + SelectedListBoxData.ContentCode）; 
} 

I am stuck. I have a WPF page with a listbox that has binding values from codebehind(.cs) file. The text displayed is Active, Pending, Discharged, etc. When I select Active, I need to get string "A". How do I do this?

In the XAML

DisplayMemberPath="ContentName" ItemsSource="{Binding}" SelectedValuePath="ContentCode">

In the CS

public PatientSearch()
{
    InitializeComponent();

    var data = new[] {
       new ListBoxData {ContentCode="A", ContentName="Active"} ,
       new ListBoxData {ContentCode="P", ContentName="Pending"} ,
       new ListBoxData {ContentCode="D", ContentName="Discharge"} ,
       new ListBoxData {ContentCode="I", ContentName="Interrupted"},
       new ListBoxData {ContentCode = "X", ContentName = "Archived"}
    };
    // Bind Array List with the ListBox
    LbPatStat.ItemsSource = data;
}

public class ListBoxData
{
    public string ContentCode { get; set; }
    public string ContentName { get; set; }
}

What I have tried:

I have tried to use IF/Else ans Switch statements, but each of them pass Active and not A...

解决方案

Hi, just do the following in ListBox SelectionChanged event,

private void LbPatStat_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
   ListBoxData SelectedListBoxData = (ListBoxData)LbPatStat.SelectedItem;
   MessageBox.Show("SelectedListBoxData : " + SelectedListBoxData.ContentCode);
}
