Public MustInherit Class Tool 
   Inherits System.ComponentModel.Component

public abstract class Tool : System.ComponentModel.Component

The ButtonStyle property is now on the Button class only. If you need to iterate through tools and change the ButtonStyle, you must cast the tool to Button and check for null before attempting to change the ButtonStyle

C#

Private void arv_Load(object sender, System.EventArgs e)
{
    DataDynamics.ActiveReports.Toolbar.Separator sep = new DataDynamics.ActiveReports.Toolbar.Separator();
    System.Drawing.Size s = new Size(20,10);
    sep.Enabled = true;
    sep.Id = 777;
    sep.Size = s;
    sep.ToolTip = "Do not click here.";
    sep.Visible = true;
    //insert the tool between the single & multipage icons
    arv.Toolbar.Tools.Insert(9, sep);

    rptDD rpt = new rptDD();
    rpt.Run();
    arv.Document = rpt.Document;
}
