Apply tooltips to the thumbnails of RadImageGallery

HOW-TO

Apply a tooltip to the thumbnails of RadImageGallery

DESCRIPTION

I would like to show the tooltip of the image title when the cursor is hovered over the thumbnail. Any way that can be done?

SOLUTION

You can access the HTML elements of the Thumbnails on the client-side using the get_items() method and set their title attributes as shown below:

<telerik:RadImageGallery RenderMode="Lightweight" runat="server" ID="RadImageGallery1" DisplayAreaMode="Thumbnails" Width="600px"
    Visible="true" ImagesFolderPath="~/images">
    <ImageAreaSettings Height="500px" />
    <ThumbnailsAreaSettings Height="200" ShowScrollButtons="false" />
</telerik:RadImageGallery>
<script>
    function pageLoad(sender, args) {
        var items = $find('<%= RadImageGallery1.ClientID %>').get_items();

        for (var i = 0; i <= items.get_count(); i++) {
            var item = items.getItem(i);
            item.get_thumbnailElement().title = "My ToolTip " + i;
        }
    }
</script>
