如何加入两个参数的值？（Visual Studio 2008 年报告）

Question

我在 Visual Studio Reports 2008 中有一份报告。我的报表包含数据源2，每个数据源都有参数。

如何连接两个参数的值？

示例：参数1的值，参数2的值

Group1,Class1

Group2, Class1

Group3, Class1

Group4, Class2

Group5, Class2

Group6, Class2

Group7, Class2

Group8, Class2

Group9, Class3

Group10, Class3

Group11, Class3

Group12, Class3

Group13, Class3

我创建了 3 个参数并添加了以下功能（在参数属性 - 可用值 - Select 指定值 - 添加功能）：

=IIf(Parameters!ReportParameter1.Value = " Group1"," Group2"," Group3" THEN Parameters!ReportParameter2.Value = " Class1")

或

IIf(Parameters!ReportParameter1.Value = " Group4"," Group5"," Group6"," Group7"," Group8" THEN Parameters!ReportParameter2.Value = " Class2")

或

IIf(Parameters!ReportParameter1.Value = " Group9"," Group10"," Group11"," Group12"," Group13" THEN Parameters!ReportParameter2.Value = " Class3")

Answer 1

您可以使用表达式根据参数 1 为参数 2 设置一个确定的值。

如果您的参数 1 允许多个值 select 离子，您可以使用 IndexOf 函数。在参数 2 属性的默认值选项卡中，select 指定值并添加新表达式，使用以下内容：

=Switch(
Array.IndexOf(Parameters!MyParam1.Value,"Group1")>-1,"Class1",
Array.IndexOf(Parameters!MyParam1.Value,"Group2")>-1,"Class1",
Array.IndexOf(Parameters!MyParam1.Value,"Group3")>-1,"Class1",
Array.IndexOf(Parameters!MyParam1.Value,"Group4")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group5")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group6")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group7")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group8")>-1,"Class2",
Array.IndexOf(Parameters!MyParam1.Value,"Group9")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group10")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group11")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group12")>-1,"Class3",
Array.IndexOf(Parameters!MyParam1.Value,"Group13")>-1,"Class3"
)

否则，如果您的参数不允许多个值，您可以简单地使用：

=Switch(
Parameters!MyParam1.Value = "Group1","Class1",
Parameters!MyParam1.Value = "Group2","Class1",
Parameters!MyParam1.Value = "Group3"1,"Class1",
Parameters!MyParam1.Value = "Group4","Class2",
Parameters!MyParam1.Value = "Group5","Class2",
Parameters!MyParam1.Value = "Group6","Class2",
Parameters!MyParam1.Value = "Group7","Class2",
Parameters!MyParam1.Value = "Group8","Class2",
Parameters!MyParam1.Value = "Group9","Class3",
Parameters!MyParam1.Value = "Group10","Class3",
Parameters!MyParam1.Value = "Group11","Class3",
Parameters!MyParam1.Value = "Group12","Class3",
Parameters!MyParam1.Value = "Group13","Class3"
)

I recommend you set the Parameter 2 to be hidden in order to avoid user change manually the value of the parameter.

如果有帮助请告诉我。

Answer 2

参数1和2允许多值选择

使用新的表达式和参数值的选择显示错误： "Error in the local report processing. parameter2"

=开关（

Array.IndexOf(参数!MyParam1.Value,"Group1")>-1,"Class1",

Array.IndexOf(参数!MyParam1.Value,"Group2")>-1,"Class1",

Array.IndexOf(参数!MyParam1.Value,"Group3")>-1,"Class1",

Array.IndexOf(参数!MyParam1.Value,"Group4")>-1,"Class2",

Array.IndexOf(参数!MyParam1.Value,"Group5")>-1,"Class2",

Array.IndexOf(参数!MyParam1.Value,"Group6")>-1,"Class2",

Array.IndexOf(参数!MyParam1.Value,"Group7")>-1,"Class2",

Array.IndexOf(参数!MyParam1.Value,"Group8")>-1,"Class2",

Array.IndexOf(参数!MyParam1.Value,"Group9")>-1,"Class3",

Array.IndexOf(参数!MyParam1.Value,"Group10")>-1,"Class3",

Array.IndexOf(参数!MyParam1.Value,"Group11")>-1,"Class3",

Array.IndexOf(参数!MyParam1.Value,"Group12")>-1,"Class3",

Array.IndexOf(参数!MyParam1.Value,"Group13")>-1,"Class3"

)
