vm层主要代码：
pravite _displayData;
public ObservableCollection<CompareDiplayData> DisplayData
{
get { return _displayData; }
}
_displayData中的数据会变化
m层
public class CompareDiplayData : INotifyPropertyChanged
{
private string _key;
public string Key
{
set
{
_key = value;
this.Changed("Key");
}
get
{
return _key;
}
}
private string _projectData;
public string ProjectData
{
set
{
_projectData = value;
this.Changed("ProjectData");
}
get
{
return _projectData;
}
}
public event PropertyChangedEventHandler PropertyChanged;
private void Changed(string PropertyName)
{
if (this.PropertyChanged != null)
this.PropertyChanged(this, new PropertyChangedEventArgs(PropertyName));
}
}
v层：
<ListView HorizontalAlignment="Left" Name="comparelistview" VerticalAlignment="Top" Width="600" Height="340" ItemsSource="{Binding DisplayData}">
<ListView.View>
<GridView>
<GridViewColumn Width="150" Header="Key"
DisplayMemberBinding="{Binding Path=Key}" />
<GridViewColumn Width="150" Header="Project Data"
DisplayMemberBinding="{Binding Path=ProjectData}" />
</GridView>
</ListView.View>
</ListView>
不知道到为什么数据就是显示不了。
