TreeView的SelectedNodeStyle和HoverNodeStyle不能共存吗

Question

我想做TreeView选中的时候，背景是红色，鼠标移上去的时候，背景是绿色，

可我发现TreeView的SelectedNodeStyle和HoverNodeStyle不能共存

要实现这两种效果，该怎么办呢

Answer 1

<asp:TreeView ID="TreeView1" runat="server" HoverNodeStyle-BackColor="Green" 
        SelectedNodeStyle-BackColor=Red EnableViewState="False">
<HoverNodeStyle BackColor="Green"></HoverNodeStyle>

<SelectedNodeStyle BackColor="Red"></SelectedNodeStyle>
        <Nodes>
          <asp:TreeNode Text="中国" Value="中国">
            <asp:TreeNode Text="河南" Value="河南" ></asp:TreeNode>
            <asp:TreeNode Text="河北" Value="河北"></asp:TreeNode>
          </asp:TreeNode>
        </Nodes>
      </asp:TreeView>

努力+方法=成功

Answer 2

如果节点是动态生成的，就失效了

Answer 3

<asp:TreeView ID="TreeView2" runat="server" HoverNodeStyle-BackColor="Green" 
    SelectedNodeStyle-BackColor=Red >
  </asp:TreeView>

 protected void Page_Load(object sender, EventArgs e)
  {
  
    if (!IsPostBack)
    {
      TreeNode tn = new TreeNode();
      tn.Text = "中国";
      tn.Value = "中国";
      TreeNode tn1 = new TreeNode();
      tn1.Value = "河南";
      tn1.Text = "河南";
      tn.ChildNodes.Add(tn1);
      TreeNode tn2 = new TreeNode();
      tn2.Value = "河北";
      tn2.Text = "河北";
      tn.ChildNodes.Add(tn2);

      TreeView2.Nodes.Add(tn);
     
    }
   
   
  }
