In my navigation bar there is a WebResource.axd file embedded as an image in dll file.
The path of WebResource.axd is:
src=”/WebResource.axd?d=9M-49D3Ji5lBmHrEjR6rfTaqFb3jthECoNLnrcsU7mH8Lyg1lbLMdX-IKhDVenhWhqwKA1hi4HeD25BX0MuFZhHzfKwVNnl7K1VrsirLiJU1&t=634394609458919508″>
Perhaps a better question to ask is “How do you disable the default menu arrow image with the System.Web.Ui.WebControls.Menu control?”
The answer to that is to set the properties: DynamicEnableDefaultPopOutImage and StaticEnableDefaultPopOutImage properties.
For example:
That will remove the rendering of the default image.
