| -- 作者：blsu33 -- 发布时间：2015/4/28 11:43:00 -- 明白了，老师代码改为下面的 If Vars("Tree") = True Then Dim tr1 As WinForm.TreeView = e.Form.Controls("TreeView1") Dim tr2 As WinForm.TreeView = e.Form.Controls("TreeView2") Dim nd1 As WinForm.TreeNode = tr1.SelectedNode Dim nd2 As WinForm.TreeNode = tr2.SelectedNode Dim Vals() As String = ND2.FullPath.Split("\\") Dim Filter As String = "功能主模块 = \'" & Vals(0) & "\' AND 一级模块 = \'" & Vals(1) & "\' AND 二级模块 = \'" & Vals(2) & "\' AND 权限 = \'" & Vals(3) & "\'" Dim dr As DataRow = DataTables("权限管理").Find(Filter) If DR IsNot Nothing Then If nd2.Checked = True Then dr("角色") = nd1.Text + "/" + dr("角色") Else dr("角色") = dr("角色").Replace(nd1.Text,"") End If dr("角色") = dr("角色").Trim("/") End If For Each nd As WinForm.TreeNode In e.Node.AllNodes nd.Checked = e.Node.Checked Next End If |
