TreeView checkbox选中后取不到值

Question

代码如下：
前台：
 <asp:TreeView ID="treeMenu" runat="server" ExpandDepth="0" Font-Names="宋体" Font-Size="12px" ShowCheckBoxes="All" ForeColor="Black">
          <LeafNodeStyle CssClass="treeRightCss table" />CS:
 if (node == null)
            {
                foreach (TreeNode treeNode in this.treeMenu.Nodes)
                {
                    if (treeNode.Checked && treeNode.ChildNodes.Count == 0)
                        this.Items += treeNode.Text.Trim() + ",";
                    if (treeNode.ChildNodes.Count > 0)
                        SaveItemsTreeNode(treeNode);
                }
            }
            else
            {
                foreach (TreeNode treeNode in node.ChildNodes)
                {
                    if (treeNode.Checked & treeNode.ChildNodes.Count == 0)
                        this.Items += treeNode.Text.Trim() + ",";                    if (treeNode.ChildNodes.Count > 0)
                        SaveItemsTreeNode(treeNode);
                }
            }但是情况是 我checkbox选中了 在CS里面也取不到值，他的checked属性依然是false 这是为什么。怎么解决啊
