As you probably would notice, the RadTreeView for ASP.NET AJAX has a much more flexible HTML structure, allowing advanced styling.

The line images in RadTreeView for ASP.NET AJAX are rendered as background images of different elements; it is recommended to copy the declarations and the images from an existing skin that resembles the skin you are migrating. If you wish to to create the images on your own, you could use the following CSS rules:

CopyCSS
.RadTreeView_{SkinName} .rtLines .rtLI,
.RadTreeView_{SkinName} .rtLines .rtFirst .rtUL
{
   background:url(NodeSpan.gif) repeat-y 0 0;
}
.RadTreeView_{SkinName} .rtLines .rtFirst
{
   background:url(FirstNodeSpan.gif) no-repeat 0 15px;
}
.RadTreeView_{SkinName} .rtLines .rtFirst .rtUL
{
   background:url(FirstNodeSpan.gif) repeat-y 0 15px;
}
.RadTreeView_{SkinName} .rtLines .rtLast,
.RadTreeView_{SkinName} .rtLines .rtLast .rtUL
{
   background:none;
}
.RadTreeView_{SkinName} .rtLines .rtTop
{
   background:url(TopLine.gif) 0 0 no-repeat;
}
.RadTreeView_{SkinName} .rtLines .rtLast .rtTop
{
   background:url(SingleLine.gif) 0 0 no-repeat;
}
.RadTreeView_{SkinName} .rtLines .rtMid
{
   background:url(MiddleLine.gif) 0 0 no-repeat;
}
.RadTreeView_{SkinName} .rtLines .rtBot
{
   background:url(BottomLine.gif) 0 0 no-repeat;
}
