如何使用复选框配置 ASP .Net 树视图的垂直间距

Question

显示很糟糕；行与行之间有一些空格。

我在网页中使用 asp:treeview 。外观是用皮肤配置的。TreeViewSkin 被写入 App_Themes 下可用的 SkinFile.skin 中：

<asp:TreeView SkinID="TreeViewSkin" runat="server" ShowLines="true" ShowCheckBoxes="All" Style="margin-top:10px;">
  <HoverNodeStyle Font-Underline="True" ForeColor="#5555DD" />
  <NodeStyle Font-Names="Verdana" Font-Size="8pt" HorizontalPadding="5px" NodeSpacing="0px" VerticalPadding="0px" />
  <ParentNodeStyle Font-Bold="False" />
  <SelectedNodeStyle Font-Underline="True" ForeColor="#5555DD" HorizontalPadding="0px" VerticalPadding="0px" />
</asp:TreeView>

有关信息，数据绑定由 完成>BuildTreeview 方法：

public static void BuildTreeView<T>(this IEnumerable<HierarchyNode<T>> hierarchy, TreeView treeView, string idName, string libName) where T : class
{
    TreeNode treeNode = null;
    var treeview = typeof(T);
    foreach (var obj in hierarchy)
    {
        var nameProperty = obj.GetType().GetProperty("Entity");
        if (nameProperty == null) continue;
        var value = (T)nameProperty.GetValue(obj, null);
        var property = treeview.GetProperty(idName, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance);
        var curElementIdValue = Convert.ToInt32(property.GetValue(value, null));

        var labelProperty = treeview.GetProperty(libName, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance);
        var labelValue = (string)labelProperty.GetValue(value, null);

        if (value != null)  treeNode = new TreeNode() {Text = labelValue, Value = curElementIdValue.ToString()};

        var childNodes = obj.GetType().GetProperty("ChildNodes");
        if (childNodes != null) {
            var propValue = childNodes.GetValue(obj, null);
            BuildTreeNode<T>(propValue as IEnumerable, treeNode, idName, libName);
        }
        if (treeNode != null) treeView.Nodes.Add(treeNode);
    }
}

我不是代码的所有者；我承认该方法的代码有些晦涩...... 显示复选框是否错误？我可以使用 Chrome 使用此 示例 进行部分复制但在 IE7 中不行。我很失望;)

我在 blogs.msdn.com

The {DIV} tag generated height is only 1px instead of 20px.
