Remarks

This property is not supported in the .NET 4.0 rendering mode. If this property is required, you can set the menu to the .NET 3.5 rendering mode by adding the following in the page's code:

menuInstance.RenderingCompatibility = new Version(3, 5);

Use the ScrollDownImageUrl property to specify a custom image to display at the bottom of each dynamic menu to indicate that the user can scroll down for additional menu items.

Note

If this property is not set, the internal, default image is used.

You can specify alternate text for the image by setting the ScrollDownText property.
