Best way to make WPF ListView GridView sort on column-header clicking

Question

There are lots of solutions on the internet attempting to fill this seemingly very-basic omission from WPF  I m really confused as to what would be the  best  way  For example    I want there to be little up down arrows in the column header to indicate sort direction  There are apparently like 3 different ways to do this  some using code  some using markup  some using markup-plus-code  and all seeming rather like a hack   Has anyone run into this problem before  and found a solution they are completely happy with  It seems bizarre that such a basic WinForms piece of functionality is missing from WPF and needs to be hacked in

Just wanted to add another simple way someone can sort the the WPF ListView void SortListView ListView listView        IEnumerable listView items   listView Items SourceCollection      List lt MY ITEM CLASS gt  listView items to list   listView items Cast lt MY ITEM CLASS gt    ToList         Comparer lt MY ITEM CLASS gt  scoreComparer   Comparer lt MY ITEM CLASS gt  Create  first  second    gt  first COLUMN NAME CompareTo second COLUMN NAME         listView items to list Sort scoreComparer       listView ItemsSource   null      listView Items Clear        listView ItemsSource   listView items to list

If you have a listview and turn it into a gridview you can easily make your gridview columns headers clickable by doing this            lt Style TargetType  GridViewColumnHeader  gt               lt Setter Property  Command  Value   Binding CommandOrderBy    gt               lt Setter Property  CommandParameter  Value   Binding RelativeSource  RelativeSource Self  Path Content    gt           lt  Style gt    Then just set a delegate command in your code       public DelegateCommand CommandOrderBy   get   return new DelegateCommand Delegated CommandOrderBy            private void Delegated CommandOrderBy object obj                throw new NotImplementedException            Im going to assume you all know how to make the ICommand DelegateCommand here  this allowed me to keep all my View clicking in the ViewModel   I only added this so that there is multiple ways to accomplish the same thing  I did not write code for adding arrow buttons in the header  but that would be done in XAML style  you would need to redesign the entire header which JanDotNet has in their code

It all depends really  if you re using the DataGrid from the WPF Toolkit then there is a built in sort  even a multi-column sort which is very useful  Check more out here   Vincent Sibals Blog  Alternatively  if you re using a different control that doesn t support sorting  i d recommend the following methods   Li Gao s Custom Sorting  Followed by   Li Gao s Faster Sorting

I use MVVM  so I created some attached properties of my own  using Thomas s as a reference   It does sorting on one column at a time when you click on the header  toggling between Ascending and Descending   It sorts from the very beginning using the first column   And it shows Win7 8 style glyphs   Normally  all you have to do is set the main property to true  but you have to explicitly declare the GridViewColumnHeaders     lt Window xmlns local  clr-namespace MyProjectNamespace  gt     lt Grid gt       lt ListView local App EnableGridViewSort  True  ItemsSource   Binding LVItems   gt         lt ListView View gt           lt GridView gt             lt GridViewColumn DisplayMemberBinding   Binding Property1   gt               lt GridViewColumnHeader Content  Prop 1    gt             lt  GridViewColumn gt             lt GridViewColumn DisplayMemberBinding   Binding Property2   gt               lt GridViewColumnHeader Content  Prop 2    gt             lt  GridViewColumn gt           lt  GridView gt         lt  ListView View gt       lt  ListView gt     lt  Grid gt   lt Window gt    If you want to sort on a different property than the display  than you have to declare that

I wrote a set of attached properties to automatically sort a GridView  you can check it out here  It doesn t handle the up down arrow  but it could easily be added    lt ListView ItemsSource   Binding Persons             IsSynchronizedWithCurrentItem  True            util GridViewSort AutoSort  True  gt       lt ListView View gt           lt GridView gt               lt GridView Columns gt                   lt GridViewColumn Header  Name                                  DisplayMemberBinding   Binding Name                                   util GridViewSort PropertyName  Name   gt                   lt GridViewColumn Header  First name                                  DisplayMemberBinding   Binding FirstName                                   util GridViewSort PropertyName  FirstName   gt                   lt GridViewColumn Header  Date of birth                                  DisplayMemberBinding   Binding DateOfBirth                                   util GridViewSort PropertyName  DateOfBirth   gt               lt  GridView Columns gt           lt  GridView gt       lt  ListView View gt   lt  ListView gt

MSDN has an easy way to perform sorting on columns with up down glyphs  The example isn t complete  though - they don t explain how to use the data templates for the glyphs  Below is what I got to work with my ListView  This works on  Net 4   In your ListView  you have to specify an event handler to fire for a click on the GridViewColumnHeader  My ListView looks like this    lt ListView Name  results  GridViewColumnHeader Click  results Click  gt       lt ListView View gt           lt GridView gt               lt GridViewColumn DisplayMemberBinding   Binding Path ContactName   gt                   lt GridViewColumn Header gt                       lt GridViewColumnHeader Content  Contact Name  Padding  5 0 0 0  HorizontalContentAlignment  Left  MinWidth  150  Name  ContactName    gt                   lt  GridViewColumn Header gt               lt  GridViewColumn gt               lt GridViewColumn DisplayMemberBinding   Binding Path PrimaryPhone   gt                   lt GridViewColumn Header gt                       lt GridViewColumnHeader Content  Contact Number  Padding  5 0 0 0  HorizontalContentAlignment  Left  MinWidth  150  Name  PrimaryPhone   gt                   lt  GridViewColumn Header gt               lt  GridViewColumn gt           lt  GridView gt       lt  ListView View gt   lt  ListView gt    In your code behind  set up the code to handle the sorting      Global objects BindingListCollectionView blcv  GridViewColumnHeader  lastHeaderClicked   null  ListSortDirection  lastDirection   ListSortDirection Ascending      Header click event void results Click object sender  RoutedEventArgs e        GridViewColumnHeader headerClicked       e OriginalSource as GridViewColumnHeader      ListSortDirection direction       if  headerClicked    null            if  headerClicked Role    GridViewColumnHeaderRole Padding                if  headerClicked     lastHeaderClicked                        direction   ListSortDirection Ascending                    else                       if   lastDirection    ListSortDirection Ascending                                direction   ListSortDirection Descending                            else                               direction   ListSortDirection Ascending                                   string header   headerClicked Column Header as string          Sort header  direction            if  direction    ListSortDirection Ascending                        headerClicked Column HeaderTemplate                 Resources  HeaderTemplateArrowUp   as DataTemplate                    else                       headerClicked Column HeaderTemplate                 Resources  HeaderTemplateArrowDown   as DataTemplate                        Remove arrow from previously sorted header         if   lastHeaderClicked    null  amp  amp   lastHeaderClicked    headerClicked                         lastHeaderClicked Column HeaderTemplate   null                      lastHeaderClicked   headerClicked           lastDirection   direction              Sort code private void Sort string sortBy  ListSortDirection direction        blcv SortDescriptions Clear        SortDescription sd   new SortDescription sortBy  direction       blcv SortDescriptions Add sd       blcv Refresh        And then in your XAML  you need to add two DataTemplates that you specified in the sorting method    lt DataTemplate x Key  HeaderTemplateArrowUp  gt       lt DockPanel LastChildFill  True  Width   Binding ActualWidth  RelativeSource  RelativeSource FindAncestor  AncestorType  x Type GridViewColumnHeader     gt           lt Path x Name  arrowUp  StrokeThickness  1  Fill  Gray  Data  M 5 10 L 15 10 L 10 5 L 5 10  DockPanel Dock  Right  Width  20  HorizontalAlignment  Right  Margin  5 0 5 0  SnapsToDevicePixels  True   gt           lt TextBlock Text   Binding      gt       lt  DockPanel gt   lt  DataTemplate gt    lt DataTemplate x Key  HeaderTemplateArrowDown  gt       lt DockPanel LastChildFill  True  Width   Binding ActualWidth  RelativeSource  RelativeSource FindAncestor  AncestorType  x Type GridViewColumnHeader     gt           lt Path x Name  arrowDown  StrokeThickness  1  Fill  Gray   Data  M 5 5 L 10 10 L 15 5 L 5 5  DockPanel Dock  Right  Width  20  HorizontalAlignment  Right  Margin  5 0 5 0  SnapsToDevicePixels  True   gt           lt TextBlock Text   Binding      gt       lt  DockPanel gt   lt  DataTemplate gt    Using the DockPanel with LastChildFill set to true will keep the glyph on the right of the header and let the label fill the rest of the space  I bound the DockPanel width to the ActualWidth of the GridViewColumnHeader because my columns have no width  which lets them autofit to the content  I did set MinWidths on the columns  though  so that the glyph doesn t cover up the column title  The TextBlock Text is set to an empty binding which displays the column name specified in the header

I made an adaptation of the Microsoft way  where I override the ListView control to make a SortableListView   public partial class SortableListView   ListView                       private GridViewColumnHeader lastHeaderClicked   null          private ListSortDirection lastDirection   ListSortDirection Ascending                  public void GridViewColumnHeaderClicked GridViewColumnHeader clickedHeader                        ListSortDirection direction               if  clickedHeader    null                                if  clickedHeader Role    GridViewColumnHeaderRole Padding                                        if  clickedHeader    lastHeaderClicked                                                direction   ListSortDirection Ascending                                            else                                               if  lastDirection    ListSortDirection Ascending                                                        direction   ListSortDirection Descending                                                    else                                                       direction   ListSortDirection Ascending                                                                       string sortString     Binding clickedHeader Column DisplayMemberBinding  Path Path                       Sort sortString  direction                        lastHeaderClicked   clickedHeader                      lastDirection   direction                                                     private void Sort string sortBy  ListSortDirection direction                        ICollectionView dataView   CollectionViewSource GetDefaultView this ItemsSource    null   this ItemsSource   this Items                dataView SortDescriptions Clear                SortDescription sD   new SortDescription sortBy  direction               dataView SortDescriptions Add sD               dataView Refresh                      The line   Binding clickedHeader Column DisplayMemberBinding  Path Path bit handles the cases where your column names are not the same as their binding paths  which the Microsoft method does not do   I wanted to intercept the GridViewColumnHeader Click event so that I wouldn t have to think about it anymore  but I couldn t find a way to to do  As a result I add the following in XAML for every SortableListView   GridViewColumnHeader Click  SortableListViewColumnHeaderClicked    And then on any Window that contains any number of SortableListViews  just add the following code   private void SortableListViewColumnHeaderClicked object sender  RoutedEventArgs e                          Controls SortableListView sender  GridViewColumnHeaderClicked e OriginalSource as GridViewColumnHeader               Where Controls is just the XAML ID for the namespace in which you made the SortableListView control   So  this does prevent code duplication on the sorting side  you just need to remember to handle the event as above
