主题：treeview控件和临时表的使用

大家好，我想建一个窗体，窗体左边用treeview控件,右边用一个临时表，通过选择或单击左边的节点，右边临时表中显示筛选的结果（根据节点名称筛选）,出现了一个问题，就是要先选择左边的节点，再打开该窗体，右边临时表才会显示筛选的内容，怎样先单击左边的节点后，右边的临时表的内容就变化啊，不需要重负的打开窗口，谢谢了

NodeMouseClick的事件代码如下：

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree("充电柜信息","编号")
Dim dtb As New DataTableBuilder("初始化表")
dtb.AddDef("充电位号", Gettype(Integer), 150)
dtb.AddDef("姓名", Gettype(String), 150)
dtb.AddDef("部门", Gettype(String),150)
dtb.AddDef("IC卡号", Gettype(String),150)
dtb.Build()
Tables("初始化窗口_Table1").datasource= Tables("初始化表")
Dim str As String =""
Dim k As Integer=Val(e.node.name)
Vars("Num")=k
Dim tb As Table
tb=Tables("人员信息")
tb.applyfilter=False
tb.Filter="[充电位]>=" & k * 100+1 & " And [充电位]<= " & k * 100+96 & " "
If tb.Rows.count>0 Then
    tb.sort="充电位"
    For i As Integer=0 To tb.rows.count-1
        tb.Position=i
        Dim dr1  As  Row =  Tables("初始化表").AddNew()
        dr1("充电位号")=tb.current("充电位")
        dr1("姓名")=tb.current("姓名")
        dr1("部门")=tb.current("部门")
        dr1("IC卡号")=tb.current("IC卡编号")
    Next
Else
    Dim t2 As Table
    t2 = Tables("初始化表")
    If t2.Rows.count>0 Then
        For i As Integer = 0 To t2.Rows.Count-1
            t2.position=i
            t2.Current.delete()
        Next
    End If
End If

窗口加载事件(AfterLoad事件)的代码如下:

Dim trv As WinForm.TreeView = e.Form.Controls("TreeView1")
trv.BuildTree("充电柜信息","编号")
Dim t1 As Table
t1=Tables("充电柜信息")
Dim t2 As Table
t2=Tables("人员信息")
Dim dtb As new DataTableBuilder("初始化表")
dtb.AddDef("充电位号",Gettype(Integer),150)
dtb.AddDef("姓名",Gettype(String),150)
dtb.AddDef("部门",Gettype(String),150)
dtb.AddDef("IC卡号",Gettype(String),150)
dtb.Build()
Tables("初始化窗口_Table1").datasource= Tables("初始化表")
Dim m As Integer=Vars("Num")
If m>0 Then
    t2.ApplyFilter=False
    t2.filter="[充电位] >= " & m * 100 +1 & " and [充电位] <= " & m * 100 +96
    If t2.Rows.count>0 Then
        t2.Sort="充电位"
        For j As Integer=0 To t2.Rows.count-1
            t2.position=j
            Dim dr As Row=Tables("初始化表").AddNew()
            dr("充电位号")=t2.current("充电位")
            dr("姓名")=t2.current("姓名")
            dr("部门")=t2.current("部门")
            dr("IC卡号")=t2.current("IC卡编号")
        Next
        Tables("初始化窗口_Table1").datasource= Tables("初始化表")
    End If
Else
    For i As Integer=0 To t1.Rows.count-1
        t1.position=i
        Dim str As String=t1.current("编号")
        Dim k As Integer=Val(str)
        t2.ApplyFilter=False
        t2.filter="[充电位] >= " & k * 100 +1 & " and [充电位] <= " & k * 100 +96
        If t2.Rows.count>0 Then
            t2.sort="充电位"
            For j As Integer=0 To t2.Rows.count-1
                t2.position=j
                Dim dr As Row=Tables("初始化表").AddNew()
                dr("充电位号")=t2.current("充电位")
                dr("姓名")=t2.current("姓名")
                dr("部门")=t2.current("部门")
                dr("IC卡号")=t2.current("IC卡编号")
            Next
            Tables("初始化窗口_Table1").datasource= Tables("初始化表")
            Exit For
        End If
    Next
End If

请上个例子,纸上谈兵很难帮上忙

没有数据源,啥也办不了.你做个内部数据源或者ACCESS数据源的例子吧.
