删除Flex Spark数据网格中的多行

Question

I want to delete all selected rows in a Spark datagrid.

This code below accounts for the Vector indices but I cannot get it to work. It does not throw out any errors.

What am I doing wrong?

public function deleteItem(event:MouseEvent):void{     
    var sIndices:Vector.<int> = arrayGrid.selectedIndices;
    sIndices.sort(Array.NUMERIC); 

    for(var index:int = sIndices.length-1; index>=0; index--) {
        arrayColl.removeItemAt(sIndices[index]);
    }       
    arrayColl.refresh();
} 

private function convertDateFormat(item:Object,column:GridColumn):String {
    return simpleDate.format(item.itemStartDate);simpleDate.format(item.itemEndDate);
}

                <s:GridColumn dataField="tag" headerText="Priority Code" />
                <s:GridColumn width="180" dataField="itemStartDate" 
                      labelFunction="convertDateFormat" headerText="Start Date"/>
                <s:GridColumn width="180" dataField="itemEndDate"  
                      labelFunction="convertDateFormat" headerText="End Date"/>

您好像忘记了调用deleteItem方法。

<s:Button label="Remove Selected Items" click="deleteItem(event)"/>
