onexpandOrCollapseAll ag网格回调事件未触发

Question

当前，我正在ag Grid中实现RowGroup功能。默认情况下，展开/折叠可通过generalMenu选项卡使用的所有功能。全部展开或折叠全部触发时需要回调事件。

expandOrCollapseAll或onGroupExpandedOrCollapsed在全部展开/折叠后未触发。

HTML模板：

    <ag-grid-angular #agGrid style='width: 100%; height: 400px;' id='myGrid' class="ag-theme-material" 
  [columnDefs]='prop.columnDefs'
  [defaultColDef]="defaultColDef"
    [rowData]='prop.rowData'
     [getNodeChildDetails]='prop.getNodeChildDetails' 
     (gridReady)='onGridReady($event)'
    (sortChanged)='sortChanged($event)' 
    [groupSuppressAutoColumn]='true' 
    [suppressRowClickSelection]='true'
    [suppressMovableColumns]="true"
    (rowGroupOpened)='onrowGroupOpened($event)'
    [groupDefaultExpanded]='prop.groupDefaultExpanded' [animateRows]='true' [rowData]='prop.rowData' [components]='components'
    [groupSelectsChildren]='true' 
    [postSort]="prop.postSort" [sortingOrder]="prop.sortingOrder" 
    [enableServerSideSorting]="true"
    [getMainMenuItems]="prop.getMainMenuItems"
    [getContextMenuItems]="prop.getContextMenuItems"
    [enableFilter]="false"
    (columnVisible)="columnVisible($event)"
    [groupMultiAutoColumn]="true"
    (onGroupExpandedOrCollapsed)='onGroupExpandedOrCollapsed($event)'
    (expandOrCollapseAll)='onexpandOrCollapseAll($event)'></ag-grid-angular>
</div>
