could you please help me 请你帮助我好吗
I solved my problem with a help from a friend by adding the following line in LoadQuickLauchDesign 通过在LoadQuickLauchDesign中添加以下行,我在朋友的帮助下解决了我的问题
if(node.Children.Count>0) img.ImageUrl="/_layouts/images/MDNCollapsed.png"
else img.ImageUrl = "/_layouts/images/MDNExpanded.png";
instead of 代替
img.ImageUrl = "/_layouts/images/MDNExpanded.png";
and in ChildTableRow function add the following innerTrLinks.Style.Add("display", "none"); 并在ChildTableRow函数中添加以下innerTrLinks.Style.Add(“ display”,“ none”); innerTrLinks.Style.Add("visibility", "hidden");
innerTrLinks.Style.Add(“ visibility”,“ hidden”); instead of innerTrLinks.Visible = true;
而不是innerTrLinks.Visible = true; and it will work perfectly
它会完美地工作
