RDLC报告隐藏空列

Question

我有一个带有列的Tablix，我添加了这个表达式以显示此列中的数据：

=Fields!PhoneNumber.Value & System.Environment.NewLine & Fields!Email.Value & System.Environment.NewLine & Fields!Address.Value

我想要的是当一个或多个字段（PhoneNumber，Email，Address）为空时，表达式仅显示非空字段并且不显示新行

怎么做？

Answer 1

why not throw-in IIF() to only add the new line IF a value is present

    =iif( string.IsNullOrWhiteSpace( Fields!PhoneNumber.Value ), '', Fields!PhoneNumber.Value & System.Environment.NewLine ) 
& iif( string.IsNullOrWhiteSpace( Fields!EMail.Value ), '', Fields!Email.Value & System.Environment.NewLine )  & Fields!Address.Value

Could get lengthy though.
