Crystal Reports 2008 - 更改背景颜色

Question

我有一个子报表，在组页脚中，我有字符串，我正在尝试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。

如果如果 WorkID 不等于 Technical.workId 或 Development.WorkId 或 null，则我的报告为空白。

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

Answer 1

我认为你需要你的语句的一个 else 部分才能工作，如果你不想为空白记录着色.. 只需在你的 else 语句中包含 crNone 或 crWhite

希望这可以帮助，

Answer 2

您必须使用isnull明确检查 null 否则公式放弃。
