函数

Dim nd As WinForm.TreeNode = args(0)

Dim dt As DataTable = args(1)

Dim drs As List(of DataRow)

drs = dt.Select("[父零件编号] = '" & nd.name & "'")

For Each dr As DataRow In drs

Dim cd As Winform.TreeNode = nd.Nodes.Add(dr("子零件编号"),dr("物料名称"))

Functions.Execute("AddChildren",cd,dt)

窗口上由于这个结构的根是在另外一个表里的，所以就不知道如何添加进这个递归了，请帮忙看看

Dim r1 As Row = Tables("BOM管理_Table1").Current

Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")

Dim nd As WinForm.TreeNode

tr.StopRedraw()

tr.Nodes.Clear

tr.Nodes.Add(r1("物料编号"),r1("物料名称"))

For Each dr As DataRow In t.DataTable.datarows

nd = tr.Nodes.Add(dr("子零件编号"),dr("物料名称"))

Functions.Execute("AddChildren",nd,t.DataTable)

不明白说什么，是不是这样？

Dim r1 As Row = Tables("BOM管理_Table1").Current
Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nd As WinForm.TreeNode
tr.StopRedraw()
tr.Nodes.Clear
For Each dr As DataRow In t.DataTable.Select("[父零件编号] = '" & r1("物料编号") & "'")
nd = tr.Nodes.Add(dr("子零件编号"),dr("物料名称"))
Functions.Execute("AddChildren",nd,t.DataTable)
Next

不是的，窗口中的代码按帮助中应该是这样的

Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nd As WinForm.TreeNode
tr.StopRedraw()
tr.Nodes.Clear
'tr.Nodes.Add("全部")
For Each dr As DataRow In dt.datarows
    If dr.IsNull("父零件编号") Then
        nd = tr.Nodes.Add(dr("子零件编号"),dr("物料名称"))
        Functions.Execute("AddChildren",nd,dt)
    End If
Next

但是这个BOM结构的根物料不在这个BOM结构的表中，而是在另外一张表中

所以我不知道该如何去调用

不明白你的意思，请上传例子。

Dim r1 As Row = Tables("BOM管理_Table1").Current
Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nd As WinForm.TreeNode
tr.StopRedraw()
tr.Nodes.Clear

Dim fdr As DataRow = DataTables("另一个表").Find("xxxxx")

For Each dr As DataRow In t.DataTable.Select("[父零件编号] = '" & fdr("物料编号") & "'")
nd = tr.Nodes.Add(dr("子零件编号"),dr("物料名称"))
Functions.Execute("AddChildren",nd,t.DataTable)
Next

这样？

Dim t As Table = Tables("表B")
Dim r1 As Row = Tables("表A").Current
Dim tr As WinForm.TreeView = e.Form.Controls("TreeView1")
Dim nd As WinForm.TreeNode
tr.StopRedraw()
tr.Nodes.Clear
Dim d As WinForm.TreeNode = tr.Nodes.Add(r1("物料编号"),r1("物料名称"))
For Each dr As DataRow In t.DataTable.Select("[父零件编号] = '" & r1("物料编号") & "'")
nd = d.Nodes.Add(dr("子零件编号"),dr("物料名称"))
Functions.Execute("AddChildren",nd,t.DataTable)
Next

good
