DetailsView Update / Insert适用于localhost而非Web服务器

标签： asp.net vb.net detailsview

我发现的所有研究都在讨论那些无法使用它的人（在DetailsView中插入/更新）。我的代码在通过VS2012运行时有效，但在我将网站复制到我的网络服务器时没有。

DetailsView链接按钮及其工作地点：

  • 编辑：开发和Web服务器
  • 更新：仅限开发
  • 取消：开发和Web服务器
  • 删除：开发和Web服务器
  • 新：开发和Web服务器
  • 插入：仅限开发

当我将文件复制到我的网络服务器并通过我的电脑上的IE运行时，更新和插入链接按钮在我点击它们时什么也不做，就好像它们一样没有任何关系。通过点击修改链接按钮，然后点击取消链接按钮， DetailsView 将进入和退出修改模式 。通过点击新建链接按钮，然后点击取消链接按钮， DetailsView 将进入和退出插入模式

如果我在VS 2012中运行调试模式，并且只是使用托管在我本地IIS上的localhost运行站点，则上述所有工作都能很好地工作。

我检查了本地IIS和服务器的IIS之间的设置，它们看起来是一样的。

  • 的web.config
  • 默认应用
  • 网站设置，如身份验证，应用程序设置等。

在下面的代码中，您会注意到我有两组链接按钮。在DetailsView标签中设置的那些，如AutoGenerateDeleteButton =“true”等。我还在DetalsView的末尾附近定义了按钮，因为我想要更多地控制它们，如确认删除。如果我使用任何一种方式（一组注释掉）或两者都被定义，我得到相同的结果。

这是我的代码：

1 个答案:

答案 0 :(得分：0)

找到解决方案，我不知道为什么它可以在我的开发电脑上工作，而不是开始时的实际网络服务器，但现在就是。

我必须在“插入和更新”链接按钮上设置CausesValidation =“false”。如果在DetailsView定义中使用AutoGenerateEditButton =“true”*和其他内容，则无法设置此项。

作为测试我：

  • 删除了我在DetailsView底部附近定义的链接按钮
  • 将详细信息留在DetailsView标记
    • 中
  • 删除了所有验证器

将上述内容复制到Web服务器，一切正常。因此，在Update和Insert链接按钮上不将CausesValidation设置为false会阻止它们触发。既然我想要验证器，我就这样做了......

  • 从DetailsView
    • 中删除了自动生成链接按钮
  • 使用DetailsView底部附近的链接按钮
  • 在更新和插入链接按钮上将CausesValidation设置为false
  • 放回验证器

现在一切正常。
