Sorting A ListView By Column

Question

Currently I use a custom sorter on the listview  and i can sort the listview each time i click on the FIRST column  but it won t sort by other columns   SortStyle  Variable to determine whether it is Ascending Sort  or Descending   if  e Column    0        if  SortStyle    0                List ListViewItemSorter   customSortDsc          SortStyle   1            else               List ListViewItemSorter   customSortAsc          SortStyle   0            This works fine when sorting for the first column  but if you were to do it on any other column  it would just sort by the first column  Is there a way to sort by the column clicked

I can see that this question was originally posted 5 yrs ago when programmers had to work harder to get their desired results  With Visual Studio 2012 and beyond  a lazy programmer can go the Design View for the Listview properties settings  and click on Properties- Sorting  choose Ascending  There are plenty of other properties features to obtain the various results a lazy  aka smart  programmer can leverage

Based on the example pointed by RedEye  here s a class that needs less code   it assumes that columns are always sorted in the same way  so it handles the ColumnClick event sink internally      public

Since this is still a top viewed thread  I thought I might note that I came up with a dynamic solution to sort the listview by column  Here s the code just in case someone else wants to use it as well  It pretty much just involves sending the listview items to a datatable  sorting the default view of the datatable by the column name  using the index of the clicked column   and then overwriting that table with the defaultview totable   method  Then pretty much just add them back to the listview  And wa la  its a sorted listview by column   public void SortListView int Index                DataTable TempTable   new DataTable              Add column names to datatable from listview         foreach  ColumnHeader iCol in MyListView Columns                        TempTable Columns Add iCol Text                       Create a datarow from each listviewitem and add it to the table         foreach  ListViewItem Item in MyListView Items                         DataRow iRow   TempTable NewRow                    the for loop dynamically copies the data one by one instead of doing irow i    MyListView Subitems 1     so on             for  int i   0  i  lt  MyListView Columns Count  i                                  if  i    0                                        iRow i    Item Text                                    else                                       iRow i    Item SubItems i  Text                                              TempTable Rows Add iRow                     string SortType   string Empty            LastCol is a public int variable on the form  and LastSort is public string variable         if  LastCol    Index                        if  LastSort     ASC     LastSort    string Empty    LastSort    null                                SortType    DESC                   LastSort    DESC                             else                               SortType    ASC                   LastSort    ASC                                   else                       SortType    DESC               LastSort    DESC                     LastCol   Index          MyListView Items Clear              Sort it based on the column text clicked and the sort type  asc or desc          TempTable DefaultView Sort   MyListView Columns Index  Text         SortType          TempTable   TempTable DefaultView ToTable              Create a listview item from the data in each row         foreach  DataRow iRow in TempTable Rows                        ListViewItem Item   new ListViewItem                List lt string gt  SubItems   new List lt string gt                 for  int i   0  i  lt  TempTable Columns Count  i                                  if  i    0                                        Item Text   iRow i  ToString                                      else                                       SubItems Add iRow i  ToString                                                 Item SubItems AddRange SubItems ToArray                 MyListView Items Add Item                     This method is dynamic as it uses the existing column name and doesn t require you to know the index or name of each column or even how many columns are in the listview datatable  You can call it by doing creating an event for the listview columnclick and then SortListView e column

My solution is a class to sort listView items when you click on column header   You can specify the type of each column   listView ListViewItemSorter   new ListViewColumnSorter    listView

You can use a manual sorting algorithm like this  public void ListItemSorter object sender  ColumnClickEventArgs e                ListView list    ListView sender          int total   list Items Count          list BeginUpdate            ListViewItem   items   new ListViewItem total           for  int i   0  i  lt  total  i                          int count   list Items Count              int minIdx   0              for  int j   1  j  lt  count  j                    if  list Items j  SubItems e Column  Text CompareTo list Items minIdx  SubItems e Column  Text   lt  0                      minIdx   j              items i    list Items minIdx               list Items RemoveAt minIdx                     list Items AddRange items           list EndUpdate            this method uses selection sort in O 2 order and as Ascending  You can change the     with   lt   for a descending or add an argument for this method  It sorts any column that is clicked and works perfect for small amount of data

Use the ListView SortExpression      When multiple columns are sorted  this   property contains a comma-separated   list of the fields to sort by

I slightly modified the example from Microsoft  https   support microsoft com en-us kb 319401  This method will only sort once to sort ascending   My modifications make it sort both ways   public class ListViewItemComparer   IComparer       private int col      bool bAsc   false      public ListViewItemComparer                 col   0            public ListViewItemComparer int column  bool b                col   column          bAsc   b            public int Compare object x  object y                if  bAsc                        return String Compare   ListViewItem x  SubItems col  Text    ListViewItem y  SubItems col  Text               bAsc   false                    else                       return String Compare   ListViewItem y  SubItems col  Text    ListViewItem x  SubItems col  Text               bAsc   true                       Then I create an object of this class whenever a column header is clicked          bool sortAscending   false          private void inventoryList ColumnClick object sender  ColumnClickEventArgs e                         if   sortAscending                                sortAscending   true                            else                               sortAscending   false                            this inventoryList ListViewItemSorter   new ListViewItemComparer e Column  sortAscending

I used the same base class as that what the others seem to use only I altered it as to allow for string  date and numerical sorting   You can initialize it using a backing-field like so   private

If you are starting out with a ListView  do yourself a huge favour and use an ObjectListView instead  ObjectListView is an open source wrapper around  NET WinForms ListView  which makes the ListView much easier to use and solves lots of common problems for you  Sorting by column click is one of the many things it handles for you automatically   Seriously  you will never regret using an ObjectListView instead of a normal ListView    ObjectListView Home Page ObjectListView Nuget Package

Forget about your custom sorter  Start over using the code at the following page  It will show you how to define a class that inherits from the IComparer interface  Each line is commented out  so you can actually see what is happening  The only potential complication is how you are retrieving your Listview Items from your Listview control  Get those squared away and all you need to do is copy and paste the IComparer interface class and the columnClick method    http   support microsoft com kb 319401

I sort using column name to set any sorting specifics that may need to be handled based on data type stored in the column and or if the column has already been sorted on asc desc   Here s a snippet from my ColumnClick event handler     private void listView ColumnClick object sender  ColumnClickEventArgs e                ListViewItemComparer sorter   GetListViewSorter e Column            listView ListViewItemSorter   sorter          listView Sort               private ListViewItemComparer GetListViewSorter int columnIndex                ListViewItemComparer sorter    ListViewItemComparer listView ListViewItemSorter          if  sorter    null                        sorter   new ListViewItemComparer                       sorter ColumnIndex   columnIndex           string columnName   packagedEstimateListView Columns columnIndex  Name          switch  columnName                        case ApplicationModel DisplayColumns DateCreated              case ApplicationModel DisplayColumns DateUpdated                  sorter ColumnType   ColumnDataType DateTime                  break              case ApplicationModel DisplayColumns NetTotal              case ApplicationModel DisplayColumns GrossTotal                  sorter ColumnType   ColumnDataType Decimal                  break              default                  sorter ColumnType   ColumnDataType String                  break                     if  sorter SortDirection    SortOrder Ascending                        sorter SortDirection   SortOrder Descending                    else                       sorter SortDirection   SortOrder Ascending                     return sorter          Below is my ListViewItemComparer  public class ListViewItemComparer   IComparer       private int  columnIndex      public int ColumnIndex               get                       return  columnIndex                    set                        columnIndex   value                       private SortOrder  sortDirection      public SortOrder SortDirection               get                       return  sortDirection                    set                        sortDirection   value                       private ColumnDataType  columnType      public ColumnDataType ColumnType               get                       return  columnType                    set                        columnType   value                        public ListViewItemComparer                  sortDirection   SortOrder None             public int Compare object x  object y                ListViewItem lviX   x as ListViewItem          ListViewItem lviY   y as ListViewItem           int result           if  lviX    null  amp  amp  lviY    null                        result   0                    else if  lviX    null                        result   -1                     else if  lviY    null                        result   1                     switch  ColumnType                        case ColumnDataType DateTime                  DateTime xDt   DataParseUtility ParseDate lviX SubItems ColumnIndex  Text                   DateTime yDt   DataParseUtility ParseDate lviY SubItems ColumnIndex  Text                   result   DateTime Compare xDt  yDt                   break               case ColumnDataType Decimal                  Decimal xD   DataParseUtility ParseDecimal lviX SubItems ColumnIndex  Text Replace      string Empty  Replace      string Empty                    Decimal yD   DataParseUtility ParseDecimal lviY SubItems ColumnIndex  Text Replace      string Empty  Replace      string Empty                    result   Decimal Compare xD  yD                   break              case ColumnDataType Short                  short xShort   DataParseUtility ParseShort lviX SubItems ColumnIndex  Text                   short yShort   DataParseUtility ParseShort lviY SubItems ColumnIndex  Text                   result   xShort CompareTo yShort                   break              case ColumnDataType Int                  int xInt   DataParseUtility ParseInt lviX SubItems ColumnIndex  Text                   int yInt   DataParseUtility ParseInt lviY SubItems ColumnIndex  Text                   return xInt CompareTo yInt                   break              case ColumnDataType Long                  long xLong   DataParseUtility ParseLong lviX SubItems ColumnIndex  Text                   long yLong   DataParseUtility ParseLong lviY SubItems ColumnIndex  Text                   return xLong CompareTo yLong                   break              default                   result   string Compare                      lviX SubItems ColumnIndex  Text                      lviY SubItems ColumnIndex  Text                      false                    break                     if  SortDirection    SortOrder Descending                        return -result                    else                       return result
