我正在面临的问题，当我创建多个数据表的数据视图然后绑定不能正常工作的新实例。 Pleae帮我解决这个问题....WPF绑定Dataview不工作
有没有人有解决这个问题？请参阅以下详细信息
上一篇：
“我们正在经历的DataRowView的propertyChange事件没有引发新的数据视图instances.This似乎是一个ADO的错误，不经过WPF应用程序创建一个。新的DataView，WPF订阅从DataView的唯一成员（DataRowView）更改事件，并取消订阅旧的DataRowView中的事件。然后ADO更改新的DataView而没有任何通知，将新的DataRowView替换为旧DataRowView。到名称列会影响旧的DataRowView，并且WPF从不会听到它们，因为它正在侦听新的DataRowView。“
在此先感谢..

绑定源
- i am binding datatable source with 3 list view with differnet dataview. if we create more view instance then two way binding is not working.xaml not getting updated from source.
private void loadDatatable()
{
DataTable dt = new DataTable();
dt.Columns.Add("FirstName");
dt.Columns.Add("LastName");
dt.Columns.Add("Userid");
DataRow dr = dt.NewRow();
dr[0] = "Siva";
dr[1] = "Jagan";
dr[2] = "JS";
dt.Rows.Add(dr);
DataRow dr1 = dt.NewRow();
dr1[0] = "Raam";
dr1[1] = "John";
dr1[2] = "RJ";
dt.Rows.Add(dr1);
ListviewALL.ItemsSource = dt.DefaultView;
dv1 = new DataView(dt);
dv1.RowFilter = "FirstName like'S%'";
dv2 = new DataView(dt);
dv2.RowFilter = "FirstName like 'R%'";
Listview.ItemsSource = dv1;
Listview1.ItemsSource = dv2;
}
请张贴代码并描述发生了什么。 – 2012-04-18 01:34:13
