Remarks
If System.Web.UI.WebControls.MenuRenderingMode is set to List, or if System.Web.UI.WebControls.MenuRenderingMode is set to Default and PagesSection.ControlRenderingCompatibilityVersion is set to 4.0 or later, this property has no effect. Use the Menu.DynamicEnableDefaultPopOutImage property or the Menu.StaticEnableDefaultPopOutImage property instead of this property.
If System.Web.UI.WebControls.MenuRenderingMode is set to Table, or if System.Web.UI.WebControls.MenuRenderingMode is set to Default and PagesSection.ControlRenderingCompatibilityVersion is set to 3.5, use this property to specify a custom image that is displayed in a menu item to indicate that the menu item has a dynamic submenu. This image can be in any file format (.jpg, .gif, .bmp, and so on), as long as the client's browser supports that format.
Note
Setting this property overrides the image specified by the Menu.DynamicPopOutImageUrl and Menu.StaticPopOutImageUrl properties.
You can also disable this image in a static menu by setting this property to an empty string and setting the StaticEnableDefaultPopOutImage property to false. Similarly, you can disable this image in a dynamic menu by setting this property to an empty string and setting the DynamicEnableDefaultPopOutImage property to false.
