Select the multiple nodes without highlighting colors

Displaying only focus rectangle when selecting multiple nodes without displaying highlighting colors can be acheived by setting the SelectedNodeBackground property's value to Color.Transparent and drawing the focus rectangle in SelectedNodeBackground event.

C#

this.treeViewAdv1.SelectedNodeBackground = new Syncfusion.Drawing.BrushInfo(Color.Transparent);
void treeViewAdv1_NodeBackgroundPaint(object sender, TreeNodeAdvPaintBackgroundEventArgs e)
{
   if(this.treeViewAdv1.SelectedNodes.Count!=0)
   {
      foreach(TreeNodeAdv treenode in treeViewAdv1.SelectedNodes)
      {
         using (Pen focusPen = new Pen(Color.Black))
         {
             focusPen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot;
             Rectangle focusBounds = treenode.DragCueBounds;
             focusBounds.Size = new Size(focusBounds.Width - 1, focusBounds.Height-1);
             e.Graphics.DrawRectangle(focusPen, focusBounds);
         }
      }
   }
}

VB

Me.treeViewAdv1.SelectedNodeBackground = New Syncfusion.Drawing.BrushInfo(Color.Transparent)
Private Sub treeViewAdv1_NodeBackgroundPaint(ByVal sender As Object, ByVal e As TreeNodeAdvPaintBackgroundEventArgs)
   If Me.treeViewAdv1.SelectedNodes.Count<>0 Then
      For Each treenode As TreeNodeAdv In treeViewAdv1.SelectedNodes
          Using focusPen As Pen = New Pen(Color.Black)
              focusPen.DashStyle = System.Drawing.Drawing2D.DashStyle.Dot
              Dim focusBounds As Rectangle = treenode.DragCueBounds
              focusBounds.Size = New Size(focusBounds.Width - 1, focusBounds.Height-1)
              e.Graphics.DrawRectangle(focusPen, focusBounds)
          End Using
      Next treenode
   End If
End Sub
