Question

任何人都知道如何获取Templatefield的文本框列，使用已经在gridview所在的gridview中使用的SqlDataSource和使用更新函数的按钮字段将数据输入的数据反馈回sql数据库？我只是想知道是否有人知道如何让这个工作，因为我还没有找到任何方法这样做。

如果你们中的任何人需要更多信息来帮助你解决这个难题，请告诉我。

如果我启用编辑并更改文本框中的信息以及同一行中另一列的字段，我能够获取反馈到SQL服务器的信息，但如果我只更改了它，它将不会更新文本框中的信息，无论是处于编辑模式还是仅单击更新按钮。

因此，将SQLAatabase的属性从CompareAllValues更改为OverwriteChanges可修复此问题。它现在允许通过更改需要更新的行/列中的文本框而不必更改任何其他内容来将更改写回到sql数据库。

使用gridview / templatefield更新SQL数据库
