Angular ui-grid dynamically calculate height of the grid

Question

I am using   https   github com angular-ui ui-grid info tree gh-pages release 3 0 0-RC 18    lt div ui-grid  gridOptions  style  height 765px  gt  lt  div gt    When I hard code the value  as shown above  the grid spreads out and everything works as expected   However  if I do the following      scope gridStyle    height   numRows rowHeight  px     765px    lt div ui-grid  gridOptions  style    gridStyle    gt  lt  div gt    The height is printed in the div and div widens but the content itself widens to only around 340px  The space that is left is blank  so instead of 25 rows I see only 8  I have to scroll down  while there is a whole 400px free in the grid  The ui-grid-viewport and ui-grid-canvas are both not using this space     Why can t the ui-grid-viewport use that space

A simpler approach is set use css combined with setting the minRowsToShow and virtualizationThreshold value dynamically    In stylesheet    ui-grid   ui-grid-viewport       height  auto  important      In code  call the below function every time you change your data in gridOptions  maxRowToShow is the value you pre-defined  for my use case  I set it to 25    ES5   setMinRowsToShow          if data length is smaller  we shrink  otherwise we can do pagination       scope gridOptions minRowsToShow   Math min  scope gridOptions data length   scope maxRowToShow        scope gridOptions virtualizationThreshold    scope gridOptions minRowsToShow

I like Tony approach  It works  but I decided to implement in different way  Here my comments   1  I did some tests and when using ng-style  Angular evaluates ng-style content  I mean getTableHeight   function more than once  I put a breakpoint into getTableHeight   function to analyze this    By the way  ui-if was removed  Now you have ng-if build-in   2  I prefer to write a service like this   angular module  angularStart services   factory  uiGridService   function   http   rootScope     var factory        factory getGridHeight   function gridOptions         var length   gridOptions data length      var rowHeight   30     your row height     var headerHeight   40     your header height     var filterHeight   40     your filter height      return length   rowHeight   headerHeight   filterHeight    px     factory removeUnit   function value  unit         return value replace unit         return factory         And then in the controller write the following     angular module  app    ui grid    controller  AppController     uiGridConstants   function uiGridConstants                 Execute this when you have  scope gridData loaded       scope gridHeight   uiGridService getGridHeight  scope gridData     And at the HTML file      lt div id  grid1  ui-grid  gridData  class  grid  ui-grid-auto-resize style  height    gridHeight    gt  lt  div gt    When angular applies the style  it only has to look in the  scope gridHeight variable and not to evaluate a complete function   3  If you want to calculate dynamically the height of an expandable grid  it is more complicated  In this case  you can set expandableRowHeight property  This fixes the reserved height for each subgrid         scope gridData             enableSorting  true          multiSelect  false            enableRowSelection  true          showFooter  false          enableFiltering  true              enableSelectAll  false          enableRowHeaderSelection  false           enableGridMenu  true          noUnselect  true          expandableRowTemplate   subGrid html           expandableRowHeight  380       10 rows   30px   40px  header    40px  filters          onRegisterApi  function gridApi                 gridApi expandable on rowExpandedStateChanged  scope  function row                   var height   parseInt uiGridService removeUnit  scope jdeNewUserConflictsGridHeight  px                     var changedRowHeight   parseInt uiGridService getGridHeight row entity subGridNewUserConflictsGrid  true                     if  row isExpanded                                        height    changedRowHeight                                                        else                                       height -  changedRowHeight                                                          scope jdeNewUserConflictsGridHeight   height    px                                      columnDefs                        field   GridField1   name   GridField1   enableFiltering  true

UPDATE   The HTML was requested so I ve pasted it below    lt div ui-grid  gridOptions  class  my-grid  gt  lt  div gt    ORIGINAL   We were able to adequately solve this problem by using responsive CSS   media  that sets the height and width based on screen real estate   Something like  and clearly you can add more based on your needs     media  min-width  1024px       my-grid       width  772px          media  min-width  1280px       my-grid       width  972px          media  min-height  768px       my-grid       height  480px          media  min-height  900px       my-grid       height  615px          The best part about this solution is that we need no resize event handling to monitor for grid size changes   It just works

tony s approach does work for me but when do a console log  the function getTableHeight get called too many time sort  menu click      I modify it so the height is recalculated only when i add remove rows  Note  tableData is the array of rows   scope getTableHeight   function        var rowHeight   30     your row height    var headerHeight   30     your header height    return         height    scope gridData data length   rowHeight   headerHeight     px             scope  watchCollection  tableData   function  newValue  oldValue        angular element element 0  querySelector   grid    css  scope getTableHeight           Html   lt div id  grid1  ui-grid  gridData  class  grid  ui-grid-auto-resize  gt  lt  div gt

following  tony s approach  changed the getTableHeight   function to    lt div id  grid1  ui-grid   ctrl gridOptions  class  grid  ui-grid-auto-resize style     ctrl getTableHeight      gt  lt  div gt   getTableHeight         var offsetValue   365      return  height      parseInt window innerHeight - offsetValue      px important       the grid would have a dynamic height with regards to window height as well

I am late to the game but I found a nice solution  I created a custom attribute directive all you need to do is pass in the gridApi and it will automatically calculate the height  It also subscribes to the pagination change event so if the user changes page size it will resize   class UIGridAutoResize implements ng IDirective       link   scope  ng IScope  element  ng IAugmentedJQuery  attrs  ng IAttributes    gt  void      scope    gridApi             restrict    A        private previousValue  string      private isValid  boolean   true      private watch  any       constructor  timeout  ng ITimeoutService            UIGridAutoResize prototype link    scope  ng IScope  element  ng IAugmentedJQuery  attrs  ng IAttributes    gt                const gridOptions   scope  eval attrs uiGrid  as any              const gridApi   scope  eval attrs gridResize  as any               gridApi core on rowsRendered scope       gt                     timeout      gt                        this autoSizeGrid element  attrs  gridOptions  gridApi  false                      100                                gridApi core on filterChanged scope       gt                    this autoSizeGrid element  attrs  gridOptions  gridApi  false                                if  attrs uiGridPagination                           gridApi pagination on paginationChanged null       gt                        this autoSizeGrid element  attrs  gridOptions  gridApi  true                                                  angular element window  resize      gt                     timeout      gt                        this autoSizeGrid element  attrs  gridOptions  gridApi  false                      100                                         static Factory    ng IDirectiveFactory           const directive     timeout  ng ITimeoutService    gt                return new UIGridAutoResize  timeout                       directive   inject        timeout             return directive             private autoSizeGrid element  ng IAugmentedJQuery  attrs  ng IAttributes  gridOptions  any  gridApi  any  isPaginationChanged  boolean            gridApi core handleWindowResize                Clear empty grid message          angular element element parent    find   emptyGridMessage   remove            element find   ui-grid-viewport   css  display                 if  attrs hidePageSize                       element find   ui-grid-pager-row-count-picker   css  display    none                       let rowCount   gridApi core getVisibleRows   length           const headerElements   element find   ui-grid-header            let headerHeight   2           if  headerElements length  gt  1       If we have more than one header element the grid is using grouping             const headerElement   angular element headerElements 1                headerHeight    headerElement height              else               headerHeight    headerElements height                       if  attrs uiGridPagination                       if  rowCount  lt  1                    gridOptions enablePagination   false                  gridOptions enablePaginationControls   false                  element css  height    rowCount   30    headerHeight -

I use ui-grid - v3 0 0-rc 20 because a scrolling issue is fixed when you go full height of container  Use the ui grid autoResize module will dynamically auto resize the grid to fit your data  To calculate the height of your grid use the function below  The ui-if is optional to wait until your data is set before rendering    x000D   x000D  angular module  app    ui grid   ui grid autoResize    controller  AppController     uiGridConstants   function uiGridConstants    x000D          x000D       x000D       scope gridData     x000D        rowHeight  30     set row height  this is default size x000D            x000D         x000D     x000D          x000D   x000D       scope getTableHeight   function     x000D         var rowHeight   30     your row height x000D         var headerHeight   30     your header height x000D         return   x000D            height    scope gridData data length   rowHeight   headerHeight     px  x000D            x000D         x000D         x000D          x000D   lt div ui-if  gridData data length gt 0  id  grid1  ui-grid  gridData  class  grid  ui-grid-auto-resize ng-style  getTableHeight    gt  lt  div gt  x000D   x000D   x000D
