How can I do it?

Answer 1

The easiest way to eliminate the border around the right button element is to manipulate its Visibility property:

        RadButtonElement radButtonElement = new RadButtonElement();
        radButtonElement.Text = "";
        radButtonElement.DisplayStyle = Telerik.WinControls.DisplayStyle.Text;
        radButtonElement.TextElement.CustomFont = "TelerikWebUI";
        radButtonElement.TextElement.CustomFontSize = 10;

        radButtonElement.BorderElement.Visibility = ElementVisibility.Collapsed;

        this.radButtonTextBox1.RightButtonItems.Add(radButtonElement);

Answer 2

Property ShouldPaint is the answer:

RadButtonElement radButtonElement = new RadButtonElement();
radButtonElement.ImagePrimitive.Image = Resources.TV_search;
radButtonElement.BorderElement.ShouldPaint = false;
this.radtxtFilter.RightButtonItems.Add(radButtonElement);
