Adding Images to Items

Each RadMenuItem has a set of properties you can use to add images to your menu items. You can simply add a single image to each menu item, or you can add separate images that reflect the state of the menu item.

The image appears to the left of the menu item text (unless you are using a right-to-left orientation, in which case it appear to the right of the menu item text). By setting the Text property to an empty string, you can create menu items that consist solely of images.

The following properties let you add images to menu items:

  • ImageUrl specifies an image that is added to the menu item. This image is always used, unless you set one of the other properties to specify an alternate image to use in a specific state.

  • HoveredImageUrl specifies an image that is used when the mouse is over the menu item.

  • ImageClickedUrl specifies an image that is used when the user clicks the menu item.

  • ExpandedImageUrl specifies an image that is used when the list of child items is showing.

  • DisabledImageUrl specifies an image that is used when the item is disabled.

To set the image properties at design time, use the RadMenu Item Builder.

The following example uses the ImageUrl and HoveredImageUrl properties to create a RadMenu that uses only images for items:

RadMenu Images Only

For a live example, see Image Only.

Since Q3 2010 RadMenu provides support for sprites - two new properties have been added:EnableImageSprites for the whole menu and EnableImageSprite for every menu item. Their purpose is to replace the menu item image element with a sized span for easier use of sprites. CssClass property of the buttons should be set in order to apply the sprite background image:

<style type="text/css">
    .icon1 .rmLeftImage, .icon2 .rmLeftImage
    {
        background: transparent url('sprite.png') 0 0;
    }
    .icon2 .rmLeftImage
    {
        background-position: -16px 0;
    }
</style>

<telerik:RadMenu RenderMode="Lightweight" id="RadMenu1" runat="server" enableimagesprites="true">
   <Items>
       <telerik:RadMenuItem Text="Item1" CssClass="icon1" />
       <telerik:RadMenuItem Text="Item2" CssClass="icon2" />
       <telerik:RadMenuItem Text="Item3" EnableImageSprite="false" />
   </Items>
</telerik:RadMenu>

will be rendered like this:

<ul class="rmRootGroup rmHorizontal">
    <li class="rmItem rmFirst">
        <a href="#" class="rmLink rmRootLink icon1">
            <span title="" class="rmLeftImage"></span>
            <span class="rmText">Item1</span> 
        </a>
    </li>
    <li class="rmItem ">
        <a href="#" class="rmLink rmRootLink icon2">
            <span title="" class="rmLeftImage"></span>
            <span class="rmText">Item2</span> 
        </a>
    </li>
    <li class="rmItem rmLast">
        <a href="#" class="rmLink rmRootLink">
            <span class="rmText">Item3</span> 
        </a>
   </li>
</ul>
caution

Setting ImageUrl overrides this behavior, so it should be removed for EnableImageSprite/s to work.
