Crystal Reports 2008 - 更改背景顏色

Question

我有一個子報表，在組頁腳中，我有字符串，我正在嘗試使用以下代碼更改背景顏色。

如果 WorkID 等於 Technical.workId 或 Development.WorkId，則顏色代碼有效，但其他項目為純黑色。

如果如果 WorkID 不等於 Technical.workId 或 Development.WorkId 或 null，則我的報告為空白。

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

我認為你需要你的語句的一個 else 部分才能工作，如果你不想為空白記錄着色.. 只需在你的 else 語句中包含 crNone 或 crWhite

希望這可以幫助，
