Menu.DynamicPopOutImageUrl Property

Gets or sets the URL to a custom image that is displayed in a dynamic menu item when the dynamic menu item has a submenu.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public string DynamicPopOutImageUrl { get; set; }
<asp:Menu DynamicPopOutImageUrl="String" />

Property Value

Type: System.String
The URL to an image used to indicate that a dynamic menu item has a submenu. The default value is an empty string (""), which indicates that this property is not set.

When a dynamic menu item contains a submenu, an image can be displayed to indicate that the user can expand the menu by positioning the mouse pointer over the menu item. There are two ways to display this image:

  • Set the DynamicEnableDefaultPopOutImage property to true to use the built-in image (default).

  • Set the DynamicPopOutImageUrl property to specify a custom image.

If the DynamicPopOutImageUrl property is set, that image overrides the built-in image.

If the DynamicPopOutImageUrl property is not set and the DynamicEnableDefaultPopOutImage property is set to false, no image is displayed.

NoteNote

When you set this property, use a slash mark (/) instead of a backslash (\). If you use backslashes in the path, the specified image will not be displayed.

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

The following code example demonstrates how to use the DynamicPopOutImageUrl property to specify a custom image to display in a dynamic menu item to indicate that the menu item has a submenu.
