Crystal reports Crystal Reports 2008-更改背景颜色

我有一个子报告，在组页脚中有一个字符串，我正试图使用以下代码更改背景颜色

如果WorkID等于Technical.WorkID或Development.WorkID，则颜色代码有效，但其他项目为纯黑色

如果WorkID不等于Technical.WorkID或Development.WorkID或null，则“我的报告”为空

if 
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}<>{Technical.workId}
and {Work.WorkID}<>{Development.WorkId} Then crNoColor
else if
(
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}={Development.WorkId} 
and {Development.PlanName}={Project.ProjectName}
and {Development.devStatus} = "R" )
then crRed
else if (
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}={Development.WorkId} 
and {Development.PlanName}={Project.ProjectName}
and {Development.devStatus} = "A" )
then crYellow
else if (
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}={Tech.workId}
and ({Resource.Team Name}like "Tech*") 
and {Technical.TechStatus} = "R" )
then crRed
else if (
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}={Tech.workId}
and ({Resource.Team Name}like "Tech*") 
and {Technical.TechStatus} = "A" )
then crYellow
else if (
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}={Tech.workId}
and ({Resource.Team Name}like "QA*") 
and {Technical.TechStatus} = "R" )
then crRed
else if (
{?Pm-DB.ID}={Work.Num} 
and {Work.WorkID}={Tech.workId}
and ({Resource.Team Name}like "QA*") 
and {Technical.TechStatus} = "A" )
then crYellow

你必须用ISnull来显式地检查NULL，否则公式会放弃。

< P>我想你需要你的另一部分语句来工作，如果你不想给空白记录加颜色的话。只需在您的else语句中包含crNone或crWhite即可

希望这有帮助

我确实在开头添加了以下代码，子报表仍然没有显示任何结果：如果isnull{Development.WorkId}，那么crNoColor，否则如果isnull{Technology.WorkId}，那么crNoColorMy向Work、Development和Technology表发出我使用的是内部联接，而不是左外部联接。
