Datagrid在特定列as3中选择行 [英] Datagrid selected row at a certain column as3

问题描述

我需要通过AS3获取所选行中某列的值，该怎么做？

I need to get the value of a certain column in the selected row via AS3, how can I do this?

当我尝试 grid.SelectedItem.text ...

感谢您的帮助！我需要能够通过名称引用列，在这种情况下为ID。

Thanks for the help! I need to be able to reference the column by name, in this case "ID".

编辑：这是否需要事件或某事？不应该有这种内置的方法？你会这样想的...

Does this require an event or something? Shouldn't there be a method for this built in? You'd think so...

推荐答案

你能更具体吗？

您可以使用selectedItem.yourProperty从DataGrid获取所需的所有数据。
你可以发布一个可能使事情清晰的片段吗？

You can get get all the data you need from the DataGrid using the selectedItem.yourProperty. Can you post a snippet that might make thing clear ?

以名称引用列很简单：

myDataGrid.getColumnAt(myDataGrid.getColumnIndex('ID'))

数据位于DataGrid的dataProvider中，该列位于其他目的。

The data is in the DataGrid's dataProvider, the column is there for other purposes.

说你有一个ID属性添加到DataGrid：

Say you have an ID property added to the DataGrid:

var dp:DataProvider = new DataProvider();
for(var i:int = 0 ; i < 7; i++)
    dp.addItem({label:'label '+(i+1), ID:Math.random()});
myDataGrid.dataProvider = dp;

如果您为更改事件，您应该可以通过以下方式获取所需的数据
selectedItem ：

If you have setup a handler for the CHANGE event, you should be able to get the data you need through the selectedItem:

myDataGrid.addEventListener(Event.CHANGE, changed);

function changed(event:Event):void {
    trace('item at index ' + myDataGrid.selectedIndex + ' has ID: ' + myDataGrid.selectedItem.ID);
}
