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)];
??????? 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]);
??}
