现在，我想在动态树视图中显示它
这是我的动态树.

Now I want to show it in dynamic tree view
this is my dynamic tree.

TreeView myTreeView = new TreeView();
myTreeView.Location = new Point(100, 100);
myTreeView.CheckBoxes = true;
myTreeView.Size = new Size(200, 200);
this.Controls.Add(myTreeView);

void BuildingTree()
       {

           DataSet PrSet = "Select * from ParentTable";

           myTreeView.Nodes.Clear();

           foreach (DataRow dr in PrSet.Tables[0].Rows)
           {

               TreeNode tnParent = new TreeNode();

               tnParent.Text = dr["ParentName"].ToString();

               tnParent.Tag= dr["ParentID"].ToString();

               tnParent.Expand();

               myTreeView.Nodes.Add(tnParent);

               FillChild(tnParent,convert.toIn32(tnParent.Tag));

           }



       }
       public void FillChild(TreeNode parent, int ParentId)
       {

           DataSet ds = PDataset("Select * from ChildTable where ParentId =" + ParentId");

            foreach (DataRow dr in ds.Tables[0].Rows)
           {

               TreeNode child = new TreeNode();

               child.Text = dr["ChildName"].ToString().Trim();

               child.Tag= dr["ChildID"].ToString().Trim();

               parent.Add(child);

           }

       }

推荐答案

TreeNode具有Checked属性.当dr["active"]为"1"时，将Checked设置为true.

TreeNodes have a Checked Property. When dr["active"] is "1" set Checked to true.
