Wpf 无法在具有通过数据项集合显式添加的项的datapresenter上设置数据源

我在MainViewModel中有一个集合，如下所示

     View = new List<Group>
            { 
                new Group
                {
                    Name = "Sagar Yadwad",GroupName = string.Empty,IsEnabled = true,LdapStatus="Pending"
                },
                new Group
                {
                    Name = "Sagar Yadwad1",GroupName = string.Empty,IsEnabled = false,LdapStatus="Pending"
                }

            };
        View1 = new ListCollectionView(View);

        View1.Filter = (e) =>
        {
            Group g = e as Group;
            return g.IsEnabled;
        };

View=新列表
{ 
新组
{
Name=“Sagar Yadwad”，GroupName=string.Empty，IsEnabled=true，LdapStatus=“Pending”
},
新组
{
Name=“Sagar Yadwad1”，GroupName=string.Empty，IsEnabled=false，LdapStatus=“Pending”
}
};
View1=新建ListCollectionView（视图）；
视图1.过滤器=（e）=>
{
g组=e组为对照组；
返回g.IsEnabled；
};

现在，我将上述ViewModel绑定到XamDatagrid，代码如下：-
