如何在 ItemDeleting 事件接收器方法中添加错误消息的链接？

发布于 2024-09-13 12:30:28 字数 565 浏览 3 评论 0原文

我有一个 SPList 事件接收器方法，例如：

ItemDeleting(ByVal voHttpContex As HttpContext, ByVal voProperties As Microsoft.SharePoint.SPItemEventProperties)

为了阻止不需要的操作，我使用此代码：

voProperties.Cancel = True
voProperties.ErrorMessage="This is my error message."

执行上述代码后，将显示错误页面中的错误消息。

有没有办法在此错误消息中添加指向另一个页面的 html 链接？

我试图使用“a”html 标签，但它明确显示在页面上，并且未被识别为要转换和解析的 Html 代码。有人知道如何将此链接添加到消息中吗？链接当然应该有一些名称，例如“单击此处”，而不是“http://blablabla.bla”格式。

I have an SPList event receiver method like:

ItemDeleting(ByVal voHttpContex As HttpContext, ByVal voProperties As Microsoft.SharePoint.SPItemEventProperties)

To block unwanted operation i uset this code:

voProperties.Cancel = True
voProperties.ErrorMessage="This is my error message."

After executing above code error message within error page is shown.

Is there a way to add to this error message html link to another page?

I was tying to use "a" html tag but it was displayed explicitly on page and wasn't recognized as a Html code to be transformed and parsed.
Do anybody knows how to add this link to the message? Link should have of course some name like "click here" instead of "http://blablabla.bla" format.

使用 ErrorMessage 不太可能 - SharePoint 中输出此消息的任何代码都使用 HTMLEncode 而你将无法阻止它。

使用 SP2010 .Cancel 已被折旧，您可以使用 Status = 取消WithRedirectUrl

voProperties.Status = CancelWithRedirectUrl;
// Redirect to some page that shows your error and provides link.
voProperties.RedirectUrl = "someurl.htm";

Unlikely by using ErrorMessage - whatever code in SharePoint is outputing this message is useing HTMLEncode and you're not going to be able to stop that.

With SP2010 .Cancel is depreciated and you could use Status = CancelWithRedirectUrl

voProperties.Status = CancelWithRedirectUrl;
// Redirect to some page that shows your error and provides link.
voProperties.RedirectUrl = "someurl.htm";
