help with sectionStack...

[Stem]

Hi, I have this sectionStack as below. I want to get to the TreeGrid declared in 4th section , how do I do that.. ( don't want to use ID's )

see line 5 below. tried (this.getSections())[3].getItems[0] and does getSections return list of the objects?

isc.SectionStack.create({
  visibilityMode: "multiple",
  /* Sections  3: TreeGrid */
 localFetchData: function() {
 	var localAlertGrid = (this.getSections())[3].getItems[0];
  	localAlertGrid.fetchData(null, function() {
		   localAlertGrid.getData().openAll();
	});
  },
  
  sections: [
    {
      canCollapse: false,
      showHeader: false,
	  hidden:  false,
      expanded: true,
      resizeable: false,                
      items: [  // Some items ]
    },
	{
      canCollapse: false,
      showHeader: false,
	  hidden: false,
      expanded: true,
      resizeable: false,                
      items: [   isc.DynamicForm.create({
			 // .... 
       	})
	 ]
    },
	{
      canCollapse: false,
      showHeader: false,
      expanded: true,
      resizeable: false,
	  hidden: true,                
      items: [   isc.DynamicForm.create({
				 // .... 
		})       
	 ]
    },   
    { 
      canCollapse: false,
      showHeader: false,
      resizeable: true,
      expanded: true,
      hidden: false,
      canHide: false,
     
       items: [
         isc.TreeGrid.create({
           editEvent: "none",
           editByCell: false,
           canEdit: false,
           autoSaveEdits: true,
           editOnFocus: true,
           selectOnEdit: false,
           fixedRecordHeights: false,
           wrapCells: true,
			  autoFetchData:false, 
			  dataSource: someDS,
			  loadDataOnDemand: false,
       			  headerHeight:30, 
			  cellHeight:25,		
			  openerImage: null,
			//  nodeIcon: "../images/user_16.png",  
			//  folderIcon: "../images/wksp_gp_16.png",
			  openIconSuffix: "",
			  closedIconSuffix: "",
			  alternateRecordStyles: true, 
			  selectionType: "none",
			
			  showSortArrow: "none", 
			  leaveScrollbarGap: false,   

			  height: "100%",
			//  customIconProperty: "alertCustomIcon",
			  checkboxCount: 0, 

			  fields: [
			  	 // somefield... 
			   
			  ]  
			})

  ] 
  } 
  ]            
});

Thankyou

The items are available directly on the sectionHeader returned by getSectionHeader() - so you should be able to achieve this via this.getSectionHeader(3).items[0].

Another option would be to hold onto a separate pointer to the treeGrid when you create it - for example

var treeGrid = isc.TreeGrid.create(...)

// having got the pointer you can store it wherever you like
// One option would be to hang it as a direct property on the SectionStack

isc.SectionStack.create(
   // pointer to the treeGrid
   treeGrid:treeGrid,

   ... // various properties

   sections:[
     ...
     // actually render the treeGrid in the section
     { items:[treeGrid] }
   ]
});
