主题：窗口控從副本表字段拉入產生錯誤??

测试没有问题。你删除bin文件夹，或重装foxtable看看

可能是bug，在afterLoad事件用代码绑定

e.Form.Controls("TextBox3").BindingField = "查詢作業_MAINTB.區域"

改一下代码

Case "顯示所有資料"
        If e.node.checked = False Then
            t.DataTable.LoadFilter=""
            t.DataTable.Load
           
            For Each nd As WinForm.TreeNode In tr1.allNodes '同步子节点选中状态
                nd.Checked = True
            Next
            e.node.checked = True
            flt =""

 内部函数代码，其余照着改 treeview_cnt

Dim tv As WinForm.TreeView = Forms("訊息主檔").Controls("Tvw_Left")
Dim str As String = Forms("訊息主檔").Controls("Cmb_FilterCol").text
If str > "" Then
    tv.BuildTree(Forms("訊息主檔").Controls("ComboBox_TB").Text,str.Replace(",","|"))
    For Each nd As WinForm.TreeNode In tv.AllNodes
        If IsDate(nd.Name) AndAlso nd.Name.Split(" ").Length > 1 AndAlso nd.Name.Split(" ")(1) = "00:00:00" Then
            nd.Text = nd.Text.Split(" ")(0)
        End If
        If nd.Nodes.Count > 0 Then   '  顯示統計
            nd.Text = nd.Text & " " & nd.Nodes.Count & " 筆"
        End If
    Next
    tv.Nodes.Insert("顯示所有資料",0)
    Dim ary As String() = str.Split(",")
    tv.nodes(0).text = tv.nodes(0).text & " " &  DataTables(Forms("訊息主檔").Controls("ComboBox_TB").Text).GetValues(ary(ary.Length-1)).Count & " 筆"
    msgbox(tv.nodes(0).text)
End If
