AdvancedDataGrid源码

从commitProperties()可以看出
         if (dataTips){
                    if (label.textWidth > label.width || column.dataTipFunction || column.dataTipField || grid.dataTipFunction || grid.dataTipField)  {
                        toolTip = column.itemToDataTip(_data);
                    } else {
                        toolTip = null;
                    }
                } else {
                    toolTip = null;
                }
             }
所以直接设置我们需要的toolTip就可以了

public class CustomHeaderRenderer extends AdvancedDataGridHeaderRenderer{          
            public function CustomHeaderRenderer(){
                  super();                 
            }
           override public function commitProperties():void {
              super.commitProperties();            
              if (this.listData){
　　　　　　//从render中找dataField   BaseListData(label:String, uid:String, owner:IUIComponent, rowIndex:int = 0, columnIndex:int = 0)

　　              var dg:AdvancedDataGrid = AdvancedDataGrid(this.listData.owner);  
              　　var column:AdvancedDataGridColumn =dg.columns[this.listData.columnIndex];
                      toolTip=column.dataField;
               }
           }
}
在column里加上headerRenderer="Renderer.CustomHeaderRenderer"就可以了
记得extends AdvancedDataGridHeaderRenderer,而不是AdvancedDataGridItemRenderer,不然默认的排序图标就没有了
我以前用了AdvancedDataGridItemRenderer，调了老半天，默认的排序图标就是不出来。

默认的排序图标
　　arr.sort = new Sort();
        arr.sort.fields = [new SortField("Total", false, false),new SortField("Call", false, false)];
        arr.refresh();

更改排序图标：　　　　　　　
　sortItemRenderer="VenomSortIconRenderer"　　
　　　　　　　　
override protected function createChildren():void{
   super.createChildren();
   var icon:DisplayObject = getChildByName("sortIcon");  
   if (icon == null)  {
     sortIcon = arrowDown ? _descendingIcon : _ascendingIcon;
    icon = DisplayObject(new sortIcon());
    icon.name = "sortIcon";
    addChild(icon);
   }
 }
override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void  {
   super.updateDisplayList(unscaledWidth,unscaledHeight);   
   if (unscaledWidth == 0)    return;   
   var icon:DisplayObject = getChildByName("sortIcon");    
   if (icon)   {
    icon.x = unscaledWidth - icon.width;
    icon.y = 0;
   }
  }

 

分组功能
　var gc:GroupingCollection = new GroupingCollection();
   var myGrouping:Grouping = new Grouping();
   myGrouping.fields = [new GroupingField("OrgName"),new GroupingField("Department")];
   gc.source = collegeAC;
   gc.grouping = myGrouping;
   gc.refresh();

　var adgGroup:AdvancedDataGridColumnGroup = new AdvancedDataGridColumnGroup();
   adgGroup.headerText = "Branch";
   adgGroup.children = [col2,col4];
   adg.groupedColumns = [col1,adgGroup,col3,col5];

 

更改背景　　　　　　　　　
this.background = true;  
this.backgroundColor = 0xCC0000;

showDataTips="true"
dataTipFunction="columnChart_dataTipFunc" 

  public function columnChart_dataTipFunc(item:HitData):String {         
          var cSI:ColumnSeriesItem = item.chartItem as ColumnSeriesItem;
           var el:ColumnSeries=item.element as ColumnSeries; 
           var cc:ColumnChart=el.owner as ColumnChart; 
            var ch:CategoryAxis=cc.horizontalAxis as CategoryAxis;                
           return StringUtil.substitute("<b>{0}</b><br>{1}",cSI.item[ch.categoryField],cSI.item[el.yField]);
  }
