以下代码是我做的一个按钮
Dim dt As DataTable
Dim b As New SQLGroupTableBuilder("统计表1","隐患排查表")
b.Groups.AddDef("发现时间",DateGroupEnum.Year,"年")
b.Groups.AddDef("发现时间",DateGroupEnum.Quarter,"季度")
b.Groups.AddDef("发现时间",DateGroupEnum.Month,"月")
b.Groups.AddDef("区域")
b.Groups.AddDef("班组")
b.Totals.AddDef("班组",AggregateEnum.Count,"隐患数") '根据客户列来统计记录数,也就是订单数
dt = b.Build(True) '参数设置为True,生成一个临时表,不在主界面显示
'然后根据统计表生成目录树
Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree(dt, "年|季度|月")
trv.StopRedraw
For Each nd As WinForm.TreeNode In trv.AllNodes
Dim Year As Integer = nd.DataRow("年")
Dim Quarter As Integer = nd.DataRow("季度")
Dim Month As Integer = nd.DataRow("月")
Select Case nd.Level
Case 0
nd.Text = nd.text & "年(" & dt.Compute("Sum(隐患数)","年 = " & Year) & "条)"
Case 1
nd.Text = nd.text & "季度(" & dt.Compute("Sum(隐患数)","年 = " & Year & "And 季度='" & Quarter & "'") & "条)"
Case 2
nd.Text = nd.text & "月(" & dt.Compute("Sum(隐患数)","年 = " & Year & "And 季度='" & Quarter & "'And 月='" & Month & "'") & "条)"
End Select
Next
trv.Nodes.Insert("加载所有行","加载所有行(" & dt.Compute("Sum(隐患数)") & "条)",0)
trv.ResumeRedraw
点击后会有 如下报错
