RDLC报表-分组序号

1.RowNumber("group_name")是按行每个分组重新1,2,3这样来显示的，如果需要按每个分组来显示1，并且递增，则需要通过自定义代码来控制，在报表-属性-代码里插入

Dim count As Integer
Dim GroupName As String
Public Function GroupCount(name As String) As String

If (GroupName = "") Then
count = 1
GroupName = name
GroupCount = count
Exit Function
End If

If (GroupName = name) Then
count = count
GroupCount = count
Else
GroupName = name
count = count + 1
GroupCount = count

End If


End Function

然后再报表单元格-表达式里通过来调用

=Code.GroupCount(Fields!FieldName.Value)
