Which creates the CollectionViewSource...<DataGrid HorizontalAlignment="Left" Height="210" Margin="47,153,0,0" VerticalAlignment="Top" Width="410" ItemsSource="{Binding Source={StaticResource cvsCustomers}}" CanUserAddRows="False"结合源头上我的Datagrid Which binds the source to my Datagrid private void CollectionViewSource_Filter(object sender, FilterEventArgs e) { Customer t = e.Item as Customer; if (t != null) // If filter is turned on, filter completed items. { if (t.Name.Contains(txtSearch.Text)) { e.Accepted = true; } else { e.Accepted = false; } } } 在我看来，一个过滤器And a filter in my View, 一切似乎是工作（项目被一定到网格），但我怎么刷新视图或网格，以便我可以解雇上述功能再次使电网也得到过滤？ （通过点击一个按钮真的）Everything seems to be working (items are being bounded to the grid) but how do I refresh the view or grid so I can fire of the above function again so the grid does get filtered? (by a button click really)感谢推荐答案呼叫 刷新（） 查看 属性的 CollectionViewSource 以得到它刷新。Call Refresh() on View property of CollectionViewSource to get it refreshed.如果你想这样做就按一下按钮，你需要首先从窗口资源访问CollectionViewSource然后调用视图刷新。In case you want to do it on button click, you need to access CollectionViewSource from window resources first and then call refresh on its View.((CollectionViewSource)this.Resources["cvsCustomers"]).View.Refresh(); 这篇关于WPF DataGrid的过滤 - 刷新CollectionViewSource刷新的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
