View products that this article applies to.

Symptoms

Consider the following scenario:
  • In Microsoft ASP.NET 2.0, you try to use a style object of the System.Web.UI.WebControls.WebParts.WebPartZoneBase class.
  • You try to assign the style object by using the CssClass property.
  • You try to use the style object in the WebPartZone server control.
In this scenario, the style does not change as expected. Specifically, the CssClass property does not affect the following style objects:
  • The MenuLabelHoverStyle property
  • The MenuPopupStyle property
  • The MenuVerbHoverStyle property
  • The MenuVerbStyle property
  • The MenuCheckImageStyle property

Workaround

To work around this problem, use inline style attributes for these style objects instead of using the external CssClass property. For example, do not use the following line of code. 
<MenuPopupStyle CssClass="wp_menupopup" />
Note In this example, wp_menupopup is the class name of a style rule that defines the background color for elements.

Instead, use the following line of code. 
<MenuPopupStyle backcolor="red" />
