利用的是狐爸的通用设计代码.
'------build复选筛选树
e.Form.Controls("TreeView1").BuildTree("任务追踪表", "是否逾期|责任部门|执行人")
'-----使筛选树的第一级node显示中文逾期
Dim trv1 As WinForm.TreeView = Forms("任务追踪").Controls("TreeView1")'使筛选树的第一级node显示中文逾期
For Each node As WinForm.TreeNode In trv1.Nodes
If node.text = False Then
node.text = "未逾期"
Else
'node.text = "逾期"

---通用代码
