您好网站成员， 我需要一些帮助，我已经使用此代码从三个表填充树视图使用现有的表链接：
Private Sub FillTREEVIEWTEXT()
Dim connGlobe As New SqlConnection("Data Source=ACCOUNTING\ACCOUNTING;Initial Catalog=DELLY;Integrated Security=SSPI;")
Dim pkp(0), pke(0) As DataColumn
Dim dtgroup, dtkol, dtmoin As New DataTable
Dim da As SqlDataAdapter
Dim i As Integer
Dim j As Integer
Dim k As Integer
'filling the datatables
Try
da = New SqlDataAdapter("SELECT stgrcode ,cast(stgrcode as varchar) +' / '+ cast(STGRNAME as varchar) as STGRNAME FROM tfw_accgrfixcode ORDER BY STGRCODE", connGlobe)
dtgroup.Clear()
da.Fill(dtgroup)
pke(0) = dtgroup.Columns("STGRCODE")
da = New SqlDataAdapter("SELECT stgrcode,stkolcode ,cast(stkolcode as varchar) +' / '+ cast(STKOLNAME as varchar) as STKOLNAME FROM tfw_acckolfixcode", connGlobe)
dtkol.Clear()
da.Fill(dtkol)
pke(0) = dtkol.Columns("STGRCODE")
da = New SqlDataAdapter("Select stgrcode,ukolcode ,cast(acckind as varchar) +' / '+ cast(UMOINNAME as varchar) as UMOINNAME from TFW_ACCMOFIXCODE", connGlobe)
dtmoin.Clear()
da.Fill(dtmoin)
pke(0) = dtmoin.Columns("STGRCODE")
connGlobe.Open()
'Creating the treeview
Dim tempNode As TreeNode
For i = 0 To dtgroup.Rows.Count - 1
TREEVIEW1.Nodes.Add(dtgroup.Rows(i).Item("STGRNAME"))
For j = 0 To dtkol.Rows.Count - 1
If dtgroup.Rows(i).Item("STGRCODE") = dtkol.Rows(j).Item("STGRCODE") Then
tempNode = TREEVIEW1.Nodes(i).Nodes.Add(dtkol.Rows(j).Item("STKOLNAME"))
For k = 0 To dtmoin.Rows.Count - 1
If dtkol.Rows(j).Item("STkolCODE") = dtmoin.Rows(k).Item("ukolCODE") Then
tempNode.Nodes.Add(dtmoin.Rows(k).Item("UMOINNAME"))
End If
Next
End If
Next
Next
connGlobe.Close()
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
到目前为止该应用程序运行良好，但现在我需要选择Node来通过Tree View更新表，我不知道为什么通过在文本框中选择任何父，子或孙的第一行值显示表格，换句话说，不显示文本框中所选节点的值。
这是我将win控件绑定到树视图的代码：
Private Sub TreeView1_AfterSelect(sender As Object, e As TreeViewEventArgs) Handles TREEVIEW1.AfterSelect
Dim connGlobe As New SqlConnection("Data Source=ACCOUNTING\ACCOUNTING;Initial Catalog=DELLY;Integrated Security=SSPI;")
Dim dtContinent As New DataTable
Dim da As SqlDataAdapter
Try
da = New SqlDataAdapter("SELECT g.STGRCODE ,g.STGRNAME,G.ISFIX,K.ISFIX,K.MAHIAT,k.STkolCODE,k.STGRCODE,k.STKOLNAME,m.STMOINCODE,m.UMOINNAME,m.TAFKINDNAME01,m.TAFKINDNAME02,m.TAFKINDNAME03,m.TAFKINDNAME04,m.TAFKINDNAME05,m.TAFKINDNAME06,m.TAFKINDNAME07,TAFKINDNO,TAFKINDNO1,TAFKINDNO2,TAFKINDNO3,TAFKINDNO4,TAFKINDNO5,TAFKINDNO6,ISMNDTAF01,ISMNDTAF02,ISMNDTAF03,ISMNDTAF04,ISMNDTAF05,ISMNDTAF06,ISMNDTAF07 FROM tfw_accgrfixcode as g INNER JOIN tfw_acckolfixcode AS k
ON g.stgrcode = k.stgrcode
