我正在尝试在我的报告中为Cell写一个字段表达式，我必须根据单元格中的字符串值更改单元格的背景颜色。例如：如果列中包含值“已批准”，则单元格应显示绿色背景颜色。我尝试了以下方法：
= IIF(fields!column.value = "Approved", "Green")
和
= IIF(Fields!column.Value, "Approved", "Green")
两者都没有...我知道我在语法中缺少一些东西..可能我并没有将绿色指向语法中的背景颜色。请帮忙！
IIF（Fields！column.Value =“Approved”，“Green”）的问题在于您缺少第三个参数。正确的语法是IIF（[某个布尔表达式]，[结果如果布尔表达式为真]，[结果如果布尔值为假]）
试试这个
=IIF(Fields!Column.Value = "Approved", "Green", "No Color")
以下是Expression Examples in Reporting Services的表达式示例列表
使用Color和Backcolor属性为查询编写表达式。将以下内容添加到要为其提供的颜色属性的表达式选项中
例
=iif(fields!column.value = "Approved", "Green","<other color>")
iif需要3个值，首先是相关的Column，然后第二个是处理True，第三个是处理iif语句的False
= IIF（字段！column.value =条件，“红色”，“黑色”）
= IIF（领域！ADPAction.Value.ToString（）。ToUpper的（）。包含（ “失败”）， “红”， “白”）
还需要转换为大写进行比较才是二进制测试。
您可以使用SWITCH（）函数来评估多个条件以为单元格着色。节点<BackgroundColor>是单元格填充，<Color>是字体颜色。
表达：
=SWITCH(
(
Fields!Usage_Date.Value.Contains("TOTAL")
AND (Fields!User_Name.Value.Contains("TOTAL"))
), "Black"
,(
Fields!Usage_Date.Value.Contains("TOTAL")
AND NOT(Fields!User_Name.Value.Contains("TOTAL"))
), "#595959"
,(
NOT(Fields!Usage_Date.Value.Contains("TOTAL"))
AND Fields!User_Name.Value.Contains("TOTAL")
AND Fields!OLAP_Cube.Value.Contains("TOTAL")

NOT(Fields!Usage_Date.Value.Contains("TOTAL"))
