Answer 1

数据源是一个IList , Binding后,进行Add()操作,UI也能看到, 但在UI上对IList中的某一对象进行编辑后,查询看IList中的对象数据却没有得到更新,比较了Bindin到TextBox的对象和IList中的对象,却不是同一个引用,望请各位解答,先谢了

Answer 2

其实我没看懂你的意思，我只是顺着你意思大概整理了一下代码。
如果你想下面WrapPanel里的TextBox里的内容和上面ListBox同步的话，那么它们的数据源必须严格一致。public class ClassInfo : INotifyPropertyChanged
{    public string Name { get; set; }
    public string ColorName { get; set; }
    #region INotifyPropertyChanged 成员    public event PropertyChangedEventHandler PropertyChanged;    
    public void OnPropertyChanged(string propertyName)
    { 
        if(PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName);
    
    }    #endregion    public override string ToString()
    {
        return this.Name;
    }
}public class ClassInfoCollection : System.Collections.ObjectModel.ObservableCollection<ClassInfo>
{
    public ClassInfoCollection()
    {
        Add( new ClassInfo { Name = "aaaaaaaa",  ColorName = "Red" } );
        Add(new ClassInfo { Name = "bbbbbbbb", ColorName = "Blue" });        
    }
}<Window.Resources >
    <!--<cc:ClassInfo x:Key="ci" Name="Tom" ColorName="Red">
    </cc:ClassInfo>-->
    <cc:ClassInfoCollection x:Name="MyCollection" x:Key="coll" >
        <cc:ClassInfo ColorName="ooo22yyy" Name="ccccc3333YYY"></cc:ClassInfo>
    </cc:ClassInfoCollection>
</Window.Resources>
<StackPanel DataContext="{StaticResource coll}">
    <ListBox Name="lsbMe" ItemsSource="{Binding}" Height="300" IsSynchronizedWithCurrentItem="True">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <Grid>
                    <WrapPanel>
                        <Label>Name:</Label>
                        <TextBox Width="120" Text="{ Binding Path=Name}">
                        </TextBox>
                        <Label>ColorName:</Label>
                        <TextBox Width="120" Text="{Binding Path=ColorName }"></TextBox>
                    </WrapPanel>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>    <WrapPanel>
        <TextBox Name="txtName" Width="120" Text="{Binding Name}"></TextBox>
        <TextBox Name="txtColorName" Width="120" Text="{Binding ColorName}" ></TextBox>
        <Button Name="btnShow" Click="btnShow_Click">显示源数据</Button>
    </WrapPanel></StackPanel>
