从高级数据网格复制和粘贴

Question

我需要能够使高级数据网格的一列可编辑，以便我的最终用户可以右键单击并通过剪贴板将数据从其复制到另一个源。

我期待在advanceDataGrid中实现下面的代码，而不仅仅是一个标准的Datagrid，但由于某种原因，它不起作用，我已经在另一个页面中实现了它作为dataGrid，并且工作正常。

import com.jpmc.ctrbs.dashboard.alarms.renderers.NonEditableTextInputEditor; 

if(dataFields[i] == 'EVENT_DESCRIPTION') { 
dataGridColumn.editable = true; 
dataGridColumn.itemEditor = new mx.core.ClassFactory(NonEditableTextInputEditor); 
dataGridColumn.editable = false; 
} 

Answer 1

我想通了，我有错，如果任何人有尝试同样的事情，这是我的代码中的错误是在if（数据域[I] ==“EVENT_DESCRIPTION”）{

import com.jpmc.ctrbs.dashboard.alarms.renderers.NonEditableTextInputEditor; 

if(dataGridColumn.dataField == "EVENT_DESCRIPTION") { 
dataGridColumn.editable = true; 
dataGridColumn.itemEditor = new mx.core.ClassFactory(NonEditableTextInputEditor); 
} 
else { 
dataGridColumn.editable = false; 
} 

这里是NonEditableTextInputRender.mxml，允许最终用户复制文本，但不能以任何其他方式改变它，并且只能为高级数据网格中的一列。
