我有一个自定义的高级 DataGrid, 我们使用交替项目颜色属性, 该属性显示高级 DataGrid 行的两种不同颜色。 现在数据格有 15 行, 但只有 5 行有数据, 我们只想要前 5 行显示交替颜色, 其余的只显示一个颜色 。 过去有没有人这样做过, 如果有人能解释如何这样做, 将会非常感激 。
提前感谢。

如果行 Ind 超过行数, 您必须覆盖数据格, 并覆盖绘图RowBackflor 方法。 然后设置默认颜色。 请参看下面提到的代码片断 :
public class CustomDataGrid extends AdvancedDataGrid {
protected override function drawRowBackground(s:Sprite, rowIndex:int, y:Number, height:Number, color:uint, dataIndex:int):void{
var XMLdata:XML=rowNumberToData(dataIndex) as XML;
if(XMLdata!=null){
if(XMLdata.attribute(Constants.col) != undefined && XMLdata.attribute(Constants.col) != ""){
color=XMLdata.attribute(Constants.col);
}else{
color=0xFFFFFF;
}
}
super.drawRowBackground(s,rowIndex,y,height,color,dataIndex);
}
}
当行数少于允许的高度时, 将行数设为实际行数, 或者覆盖 drawRowBackform 。
