应用脚本

为了对来自数据源的数据进行进一步处理，或者根据字段数据对报表元素的格式进行特殊的设置，可以在设计区域的上方，点击【脚本】选项卡，进入脚本编辑窗口，编写自定义的脚本函数。

脚本函数使用Visual Basic .NET编程语言，下面是一个自定义脚本函数的例子：

1.在脚本选项卡中输入正确的函数

该函数用于实现将数字转换为中文大写功能，供参考。

Function ConvertToRMB(ByVal inputString As String) As String
        Dim numList As String = "零壹贰叁肆伍陆柒捌玖"
        Dim rmbList As String = "分角元拾佰仟万拾佰仟亿拾佰仟万"
        Dim number As Double = 0
        Dim tempOutString As String = ""
        number = Double.Parse(inputString)


        Dim tempNumberString As String = Convert.ToInt64(number * 100).ToString()
        Dim tempNmberLength As Integer = tempNumberString.Length
        Dim i As Integer = 0

        While i < tempNmberLength  
                Dim oneNumber As Integer = Int32.Parse(tempNumberString.Substring(i, 1))
                Dim oneNumberChar As String = numList.Substring(oneNumber, 1)
                Dim oneNumberUnit As String = rmbList.Substring(tempNmberLength - i - 1, 1)
                If Not (oneNumberChar = "零") Then
                        tempOutString += oneNumberChar + oneNumberUnit
                Else
                        If oneNumberUnit = "亿" OrElse oneNumberUnit = "万" OrElse oneNumberUnit = "元" OrElse oneNumberUnit = "零" Then
                                While tempOutString.EndsWith("零")
                                        tempOutString = tempOutString.Substring(0, tempOutString.Length - 1)
                                End While
                        End If
                        If oneNumberUnit = "亿" OrElse (oneNumberUnit = "万" AndAlso Not tempOutString.EndsWith("亿")) OrElse oneNumberUnit = "元" Then
                                tempOutString += oneNumberUnit
                        Else
                                If Not tempOutString Is Nothing Then
                                        Dim tempEnd As Boolean = tempOutString.EndsWith("亿")
                                        Dim zeroEnd As Boolean = tempOutString.EndsWith("零")
                                        If tempOutString.Length > 1 Then
                                                Dim zeroStart As Boolean = tempOutString.Substring(tempOutString.Length - 2, 2).StartsWith("零")
                                                If Not zeroEnd AndAlso (zeroStart OrElse Not tempEnd) Then
                                                        tempOutString += oneNumberChar
                                                End If
                                        Else
                                                If Not zeroEnd AndAlso Not tempEnd Then
                                                        tempOutString += oneNumberChar
                                                End If
                                        End If
                                End If

                        End If
                End If
                i += 1

        End While
        If Not tempOutString Is Nothing Then
                While tempOutString.EndsWith("零")
                        tempOutString = tempOutString.Substring(0, tempOutString.Length - 1)
                End While
                While tempOutString.EndsWith("元")
                        tempOutString = tempOutString + "整"
                End While
                Return tempOutString
        Else
                Return ""
        End If
End Function

2.在单元格（文本框）中引用函数，设置单元格 Value 属性（注意：凡是支持【表达式】的属性均可调用脚本函数）

调用形式是：Code.函数名(参数列表) ，

= Code.ConvertToRMB(Fields!Bonus.Value)
