我想刷新我的数据网格,但刷新后,我在组内的排序不再正确......
<XmlDataProvider x:Key="SmsData" XPath="/response/conv/">
</XmlDataProvider>
<local:RowColorConverter x:Key="RowColorConverter" />
<CollectionViewSource x:Key="SmsView" Source="{StaticResource SmsData}" >
<CollectionViewSource.SortDescriptions>
<scm:SortDescription PropertyName="date" Direction="Descending" />
<scm:SortDescription PropertyName="time" Direction="Descending" />
</CollectionViewSource.SortDescriptions>
<CollectionViewSource.GroupDescriptions>
<dat:PropertyGroupDescription PropertyName="recipient" />
</CollectionViewSource.GroupDescriptions>
</CollectionViewSource>
我调用了一个按钮,该按钮引用了一种执行刷新的方法:
...
CollectionViewSource cvs = FindResource("SmsView") as CollectionViewSource;
cvs.View.Refresh();
dataGrid1.Items.Refresh();
xdp = FindResource("SmsData") as XmlDataProvider;
xdp.Document = doc;
