DataGrid也可以分组 但是用的地方不多 就没写

筛选还是可以的 比如Datagrid数据量比较大 要做数据筛选

贴码

  "datagrid"  AutoGenerateColumns="False" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch">




            




                "{Binding Name}" Header="Name">




                "{Binding Address}" Header="Address">




                "{Binding Age}" Header="Age">




            



        



        "sort" Content="排序" HorizontalAlignment="Left" Margin="466,300,0,0" VerticalAlignment="Top" Checked="CheckBox_Checked"/>




        "TxT" HorizontalAlignment="Left" Height="25" Margin="402,5,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Width="115" TextChanged="TextBox_TextChanged"/>




        "Left" Height="20" Margin="336,8,0,0" TextWrapping="Wrap" Text="筛选内容" VerticalAlignment="Top" Width="61"/>




 



 



    

        public MainWindow()




        {



            InitializeComponent();



            



                Preson = new ObservableCollection() { 




                new Preson() { Name = "慧哥1", Address = "大连1", Age = 31 },



                new Preson() { Name = "慧哥2", Address = "大连2", Age = 32 },



                new Preson() { Name = "慧哥3", Address = "大连3", Age = 33 },

                datagrid.ItemsSource = Preson;



          



        }

        }

        private void CheckBox_Checked(object sender, RoutedEventArgs e)




        {



            var cvs = CollectionViewSource.GetDefaultView(datagrid.ItemsSource);



            if(cvs!=null&&cvs.CanSort)



            {



                cvs.SortDescriptions.Clear();



                if (sort.IsChecked == true)



                {



                    cvs.SortDescriptions.Add(new System.ComponentModel.SortDescription("Age", System.ComponentModel.ListSortDirection.Descending));



                }



              



            }

            {



                cvs.Filter = OnFilterApplied;



            }



        }



 



        private bool OnFilterApplied(object obj)




        {



            if (obj is Preson) 



            {



                var text = TxT.Text.ToLower();



                return (obj as Preson).Name.ToLower().Contains(text)



                    || (obj as Preson).Address.ToLower().Contains(text);



            }



            return false;



        }



 



        



 



 



 



        



    }
