Any news on this?

Seems like documentation is wrong as well: TreeView Documentation.

Hello,

It looks like the skin images and / or the skin stylesheet are not loaded.

I believe there is a bug in the TreeView.  When I explicitly set ShowLines(false), I see that showLines:false is included in the jQuery initialization script.  However if I explicitly set ShowLines(true), then showLines:true is not included in the initialization script.

I can see that WriteInitializationScript() method does the following:

      if (!this.ShowLines)
        objectWriter.Append("showLines", this.ShowLines);

Hi Ross,

Properties with default values are not serialized, because this is not necessary. Is there a problem with the component functionality?

Ah, I thought that the default behaviour was to not show lines, but it sounds like you are saying that the default is to show lines.  I can't get the lines to appear at all.  Furthermore the lines do not appear in any of the online demos:

Thanks,

Ross.

Hello Ross,

Some themes are designed to resemble other existing themes (e.g. Windows Vista operating system) and the TreeView does not have lines at all. However, you can use a skin that has them, for example:

http://demos.telerik.com/aspnet-mvc/treeview?theme=simple

All the best,
