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)
