我定义了两个基础类，ComboboxItemInfo 是用来绑定下拉框数据的。下面是我的基础类和页面绑定的代码。
/// <summary>
/// Combobox 下拉框数据
/// </summary>
public class ComboboxItemInfo : INotifyPropertyChanged
{
private List<string> _itemDisplayInfo;
/// <summary>
/// 显示值
/// </summary>
public List<string> ItemDisylayInfo
{
get { return _itemDisplayInfo; }
set
{
if (_itemDisplayInfo != value)
{
_itemDisplayInfo = value;
NotifyPropertyChanged("ItemDisylayInfo");
}
}
}
private List<string> _itemValueInfo;
/// <summary>
/// 实际值
/// </summary>
public List<string> ItemValueInfo
{
get { return _itemValueInfo; }
set
{
if (_itemValueInfo != value)
{
_itemValueInfo = value;
NotifyPropertyChanged("ItemValueInfo");
}
}
}
//下拉框后面的textbox值
private string _itemTextBoxValue;
/// <summary>
/// Combobox后面的textbox值
/// </summary>
public string ItemTextBoxValue
{
get { return _itemTextBoxValue; }
set
{
if (_itemTextBoxValue != value)
{
_itemTextBoxValue = value;
NotifyPropertyChanged("ItemTextBoxValue");
}
}
}
//分组名称
private string _itemgroupName;
public string ItemGroupName
{
get { return _itemgroupName; }
set
{
if (_itemgroupName != value)
{
_itemgroupName = value;
NotifyPropertyChanged("ItemGroupName");
}
}
}
#region INotifyPropertyChanged
public event PropertyChangedEventHandler PropertyChanged;
protected void NotifyPropertyChanged(string propertyName)
{
if (this.PropertyChanged != null)
{
this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
#endregion
}
/// <summary>

public class KeyValue : INotifyPropertyChanged//, IDataErrorInfo
{
public int Index_Check = 0;
private List<ComboboxItemInfo> _comboBoxKeys;

private Guid _evaluationItemId;
public Guid EvaluationItemId
{
get { return _evaluationItemId; }
set
{

{
_evaluationItemId = value;
NotifyPropertyChanged("EvaluationItemId");
}
}
}
private Visibility _isHaveText;
/// <summary>

/// </summary>
public Visibility IsHaveText
{
get { return _isHaveText; }
set
{
if (_isHaveText != value)
{
_isHaveText = value;
NotifyPropertyChanged("IsHaveText");
}
}
}
private string _textInfo;
/// <summary>

public string TextInfo
{

set

PelvicFractureInfos_left[0].FingerKeys1这个属性是KeyValue类的对象。它里面包含了ComboboxItemInfo的一个列表，我下拉框的数据就是绑定的这个列表里的数据，现在目前数据都取到了，就是在下拉框中数据显示不了。
高手帮忙看下。谢谢
