所以我使用Modal Popup进行gridview编辑。 gridview是另一个gridview的子gridview。我已经将模式弹出窗口移出updatepanel，原因是它在将文本提交到数据库时在文本框的开头添加逗号。在我将模式弹出窗口移出更新面板之前，正在填充文本框，但是现在因为它不再位于具有gridview的更新面板中，所以它不会使用gridview数据填充文本框。有人有什么建议吗？

经过一段时间没有回应，我试图弄清楚这对我的环境有用。
parentoption = parentoption.Split(",").Last()
这将删除逗号和逗号前面的任何内容，以便提交的唯一文本是输入的新文本。
