  Not exists:

  UseEmbeddedVisualStyles="True"
   VisualStyle="Office2007Blue"
  VisualStylePath="~/C1WebControls/VisualStyles"

     <cc1:C1TreeView ID="C1TreeViewColumns" style="disabled:disabled" runat="server"
     AutoPostBack="false"
     OnClientNodeClicked ="C1TreeViewColumns_OnClientNodeClicked"
     ShowCheckBoxes="false" AutoCheckNodes="False"

  Hi,

  The legacy styling properties such as VisualStylePath, UseEmbeddedVisualStyles and VisualStyle are no longer present or used. Now, you can either use built-in themes, or CSS to style your control.

  Please refer to https://developer.mescius.com/componentone/docs/webforms/online-treeview/c1treeviewthemes.html for more information.

  Best Regards,
