在CaseStudy目录下的文件：会计科目.Table的示例中,假如我要增加一个会计科目:"101200,新增科目",展示结果如下:

我想实现新增科目自动按编码顺序进行排序列印,应放到第一位,即101201前面,而不是每次增加都放在在末位,需要改哪里?

Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nd As WinForm.TreeNode
Dim dt As DataTable = DataTables("会计科目")
tr.StopRedraw()
tr.Nodes.Clear
tr.Nodes.Add("全部")
For Each dr As DataRow In dt.datarows
    If dr.IsNull("科目代码") = False AndAlso dr("科目代码").Length = 4 Then
        nd = tr.Nodes.Add(dr("科目代码"),dr("科目代码") & " " & dr("科目名称"))
        Functions.Execute("AddChildren",nd,dt)
    End If
Next
tr.ResumeRedraw()

就这一段码,没有Tables控件.

我是新学的,没能看明白.

这个是使用了内部函数,不是用树型产生的.

不用排序也行，我给你完整的答案，AddChidren这个函数的代码改为：

Dim nd As WinForm.TreeNode = args(0)
Dim dt As DataTable = args(1)
For Each dr As DataRow In dt.Select("","科目代码")
    Dim km As String = dr("科目代码")
    If km.StartsWith(nd.name) AndAlso km.Length = nd.Name.Length + 2 Then
         Dim cd As Winform.TreeNode = nd.Nodes.Add(km,km & " " & dr("科目名称"))
        Functions.Execute("AddChildren",cd,dt)
    End If
Next

窗口1的AfterLoad事件代码改为：

Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nd As WinForm.TreeNode
Dim dt As DataTable = DataTables("会计科目")
tr.StopRedraw()
tr.Nodes.Clear
tr.Nodes.Add("全部")
For Each dr As DataRow In dt.Select("","科目代码")
    If dr.IsNull("科目代码") = False AndAlso dr("科目代码").Length = 4 Then
        nd = tr.Nodes.Add(dr("科目代码"),dr("科目代码") & " " & dr("科目名称"))
        Functions.Execute("AddChildren",nd,dt)
    End If
Next
tr.ResumeRedraw()
