我對Flex有些新鮮感，遇到了itemRenderer的問題，我無法找到解決方案。我問過一位有着豐富經驗的同事，我試過在沒有運氣的情況下搜索互聯網。
我的問題是，我有一個dataGrid，其中每列使用itemRenderer來顯示信息，出於某種原因，這導致用戶無法選擇任何dataGrid行。我認爲它必須與itemRenderer有關，因爲當我添加一個沒有itemRenderer的虛擬列時，我可以通過點擊該虛擬列來突出顯示並選擇一行，但其他列表仍然無法工作。我已經嘗試將我的代碼與其他dataGrids的代碼進行比較，並使用itemRenderer進行工作，但是我一直未能找到任何會導致我的問題的差異。有誰知道爲什麼會發生？
謝謝！flex itemrenderer防止datagrid項目選擇

好像你沒在的itemRenderer實現一些狀態。試試從DataGridItemRenderer類擴展你的itemRenderer類 – Anton 2014-12-05 18:37:30
