Refer : Microsoft.Web.UI.WebControls Treeview not rendering on some machines

Microsoft.Web.UI.WebControls.Treeview is an obsolete control.

The most likely reason why your tree control breaks is that it does not work on Windows 8/IE10.

Best option is to convert to System.Web.UI.WebControl.TreeView

Quick fix: add the following code to your Global.asax.vb.Application_EndRequest. This will force IE to load your application in compatibility mode.

Try

   Response.AddHeader("X-UA-Compatible", "IE=5")

Catch ex As Exception

End Try
