datagrid as3 - 如何将编辑后的单元格保存到变量

Question

我正在处理一个正在从过程中获取的变量中提取信息的数据网格。我需要能够编辑overpaidAmount列。我已经锁定了除了需要用户输入的列以外的所有列，但是一旦他们添加了信息，我该如何将它分配给变量？在网上随处看，无法找到这个具体问题的任何东西。

import fl.controls.DataGrid; 
import fl.controls.ScrollPolicy; 
import fl.data.DataProvider; 
import fl.controls.dataGridClasses.DataGridColumn; 

var col1:DataGridColumn = new DataGridColumn("Line"); 
var col2:DataGridColumn = new DataGridColumn("ServiceCode"); 
var col3:DataGridColumn = new DataGridColumn("BilledCharge"); 
var col4:DataGridColumn = new DataGridColumn("Paid"); 
var col5:DataGridColumn = new DataGridColumn("OverpaidAmount"); 

datagrid.addColumn(col1); 
datagrid.addColumn(col2); 
datagrid.addColumn(col3); 
datagrid.addColumn(col4); 
datagrid.addColumn(col5); 

col1.editable = false; 
col2.editable = false; 
col3.editable = false; 
col4.editable = false; 

col1.minWidth = 40; 
col2.minWidth = 80; 
col3.minWidth = 80; 
col4.minWidth = 80; 
col5.minWidth = 130; 

var myData:Array; 

if ((majorPercentage1 == "---") || (majorPercentage1 == "000") || (majorPercentage1 == " ")) 
{ 
    myData = 
    [ 
     {Line:"1", ServiceCode: cpt1, BilledCharge: charge1, Paid: basicPaid1, OverpaidAmount: overpaidAmount1}, 
     {Line:"2", ServiceCode: cpt2, BilledCharge: charge2, Paid: basicPaid2, OverpaidAmount: overpaidAmount2}, 
     {Line:"3", ServiceCode: cpt3, BilledCharge: charge3, Paid: basicPaid3, OverpaidAmount: overpaidAmount3}, 
     {Line:"4", ServiceCode: cpt4, BilledCharge: charge4, Paid: basicPaid4, OverpaidAmount: overpaidAmount4}, 
     {Line:"5", ServiceCode: cpt5, BilledCharge: charge5, Paid: basicPaid5, OverpaidAmount: overpaidAmount5} 
    ]; 
} 
else 
{ 
    myData = 
    [ 
     {Line:"1", ServiceCode: cpt1, BilledCharge: charge1, Paid: majorPaid1, OverpaidAmount: overpaidAmount1}, 
     {Line:"2", ServiceCode: cpt2, BilledCharge: charge2, Paid: majorPaid2, OverpaidAmount: overpaidAmount2}, 
     {Line:"3", ServiceCode: cpt3, BilledCharge: charge3, Paid: majorPaid3, OverpaidAmount: overpaidAmount3}, 
     {Line:"4", ServiceCode: cpt4, BilledCharge: charge4, Paid: majorPaid4, OverpaidAmount: overpaidAmount4}, 
     {Line:"5", ServiceCode: cpt5, BilledCharge: charge5, Paid: majorPaid5, OverpaidAmount: overpaidAmount5} 
    ]; 
} 
datagrid.dataProvider = new DataProvider(myData); 

任何帮助表示赞赏。

好了，所以我想出了一个解决方案，无论是做到这一点的最好办法 - 也许不是:(

我不得不创建其持有从小区信息连续连用数动态文本字段然后我创建了一个输入文本字段来显示我想要更新的变量，添加了一个更新按钮，其中包含下面的监听器，并且这样做了，只需要添加一些代码来刷新数据网格，已更新。

function griditemselected (event:Event):void{ 
overPaid_txt.text = event.target.selectedItem.OverpaidAmount; 
} 

//Find the row number of the selected item so that we can update the correct overpaid amount 
datagrid.addEventListener(ListEvent.ITEM_CLICK , gridItemSelected); 
function gridItemSelected(e:ListEvent):void { 
rowID = Number(e.rowIndex)+1; 
}  

updated_btn.addEventListener(MouseEvent.CLICK, updateOverpaid); 

function updateOverpaid(e:MouseEvent):void 
{ 
//Update the selected line overpaidAmount  
switch (rowID) 
{ 
    case 1: 
    overpaidAmount1 = overPaid_txt.text; 
    break; 

    case 2: 
    overpaidAmount2 = overPaid_txt.text; 
    break; 

    case 3: 
    overpaidAmount3 = overPaid_txt.text; 
    break; 

    case 4: 
    overpaidAmount4 = overPaid_txt.text; 
    break; 

    case 5: 
    overpaidAmount5 = overPaid_txt.text; 
    break; 
}   
//Remove all the rows and refresh with new variable for overpaid amount 
datagrid.removeAll(); 
datagrid.addItem(event1); 
datagrid.addItem(event2); 
datagrid.addItem(event3); 
datagrid.addItem(event4); 
datagrid.addItem(event5); 
}
