需要在有条件的情况下使字段强制执 [英] Need to make field conditionally mandatory

问题描述

大家好，



我要求在SharePoint列表中有条件地强制要求字段。有一个提交下拉列表。如果我在下拉列表中选择一个特定值，则另一个字段必须是强制性的，对于下拉列表中的其他值，它不一定是强制性的。



任何指针都是非常有帮助！



提前致谢。

Hi all,

I''ve a requirement to make a field in SharePoint list conditionally mandatory. There is a filed which is a dropdown. If I select one particular value in the dropdown, the other filed has to be mandatory and for other values in dropdown it need not be mandatory.

Any pointers would be of great help!

Thanks in advance.

推荐答案

解决方法是在ItemAdding上使用事件接收器（ ）事件并基于下拉列表中的值，强制用户在保存之前在字段中输入值。根据我的知识，没有OOB方式可用。

Workaround would be to use event receiver on ItemAdding() event and based on the value within the dropdown, forcing the user to enter value in the field before it can be saved. No OOB way is available as per my knowledge.
