Hi, 
i cant figure out how i can do it with a button. I can change almost everything but the backplanestyle seems to change on all shapes.

here's the code i got

foreach (NShape shape in nDrawingView1.Selection.Nodes)
    {  
      if (shape.Style == null && shape.Style.StrokeStyle == null)
      {       
      }
      else
      {
       shape.Text = "A";
       shape.Style.EndArrowheadStyle = new NArrowheadStyle(ArrowheadShape.Arrow, "", new NSizeL(5, 5), new NColorFillStyle(Color.Gray), new NStrokeStyle(1, Color.Black));
       shape.Style.StartArrowheadStyle = new NArrowheadStyle(ArrowheadShape.Arrow, "", new NSizeL(5, 5), new NColorFillStyle(Color.Gray), new NStrokeStyle(1, Color.Black));
       shape.Style.FillStyle = new NColorFillStyle(Color.Transparent);
       NTextStyle textStyle = new NTextStyle();
 
       if (shape.Style != null && shape.Style.TextStyle != null)
       {
        textStyle = shape.Style.TextStyle;
       }
       else
       {
        textStyle = shape.ComposeTextStyle();
        NStyle.SetTextStyle(shape, textStyle);
       }
       textStyle.FontStyle = new NFontStyle("Verdana", 10, FontStyle.Regular | FontStyle.Regular);
       textStyle.FillStyle = new NColorFillStyle(Color.Black);
       textStyle.BackplaneStyle.Visible = true;
       textStyle.BackplaneStyle.StandardFrameStyle.Visible = false;
      }
    }

i tried with this  but it's not working
shape.Style.TextStyle.BackplaneStyle.Visible = true;
shape.Style.TextStyle.BackplaneStyle.StandardFrameStyle.Visible = false;

Can someone give me a hint on this please ?
