想要创建多选查找列，该列将从“外部列表"获取数据. [英] Want to create Multi-select Look up column which will fetch data from "External List"

问题描述

实际上，我创建了一个外部列表，并试图创建一个查找列，该列将从该外部列表中获取数据.但是，一旦我选择了我创建的外部列表"，允许多项选择"的选项就消失了.

最后，我通过在VS 2010中进行编码成功创建了一个Lookup列，并为我的Lookup字段设置了属性myLookUpField.AllowMultipleSelection= true.它创建成功，没有任何错误.我什至可以通过查找列"进行多项选择.

但是令人惊讶的是，在我的查阅列中做出多项选择之后，我试图保存它，这会引发错误.我尝试了很多方法，但是徒劳！

所以我只想知道:
Sharepoint 2010是否支持从外部列表"中获取数据的查找列"的多选"选项?如果是，怎么办?

Actually I created one External Lists and tried to create a Lookup Column which will fetch data from this external list. But as soon as I select my External List [which I created], the option for "Allow Multiple Selection" got disappear.

Finally, I successfully created one Lookup column by coding in VS 2010 and sets the properties myLookUpField.AllowMultipleSelection= true for my Lookup field. It got created without any errors. I even got the option for making multiple selection through my Lookup Column.

BUT AMAZINGLY, after making the multiple selection in my look up column, I tried to save it which is throwing errors. I tried it in many ways, but in vain!

So I just wanted to know :
Does Sharepoint 2010 supports Multi-Select option for the Lookup-Column which is fetching data from the "External Lists"? If yes, how?

推荐答案

否！
不幸的是，对外部列表的查找不允许有多个值.

NO !
Lookups to External Lists don''t allow for multiple values unfortunately.
