The ASPxImageGallery control is available on the DX.22.1: Navigation & Layout toolbox tab in the Microsoft Visual Studio IDE.

Drag the control onto a form and customize the control’s settings, or paste the control’s markup in the page’s source code.

<dx:ASPxImageGallery ID="ASPxImageGallery" runat="server"
                     ThumbnailHeight="178px" ThumbnailWidth="178px" ClientInstanceName="ClientImageGallery" >
    <Paddings Padding="0" />
    <SettingsFolder ImageSourceFolder="~/Content/Images/photo_gallery/" ImageCacheFolder="~/Thumb/ImageGalleryThumb/" />
    <SettingsTableLayout ColumnCount="3" RowsPerPage="1" />
</dx:ASPxImageGallery>

Run Time

using DevExpress.Web;
...
protected void Page_Load(object sender, EventArgs e)
{
    ASPxImageGallery imageGallery = new ASPxImageGallery();
    imageGallery.ID = "imageGallery";
    Page.Form.Controls.Add(imageGallery);

    imageGallery.ClientInstanceName = "ClientImageGallery";
    imageGallery.Paddings.Padding = 0;
    imageGallery.SettingsTableLayout.ColumnCount = 3;
    imageGallery.SettingsTableLayout.RowsPerPage = 1;

    imageGallery.SettingsFolder.ImageSourceFolder = "~/Content/Images/photo_gallery/";
    imageGallery.SettingsFolder.ImageCacheFolder = "~/Thumb/ImageGalleryThumb/";
}

Note

DevExpress controls require that you register special modules, handlers, and options in the Web.config file. You can change this file or switch to the Design tab in the Microsoft Visual Studio IDE to automatically update the Web.config file. Note that this information is automatically registered if you use the DevExpress Template Gallery to create a project.

The ASPxImageGallery control can be populated with items in different ways:

An image gallery displays a pager that allows navigation between thumbnails. When a thumbnail is clicked, the fullscreen viewer opens.

The Image Gallery supports the virtual paging mode (ImageGalleryFullscreenViewerSettings.EnableVirtualPaging) that allows end-users to load images on demand when navigating using the pager.

Note

ASPxImageGallery control provides you with comprehensive client-side functionality implemented in JavaScript code.

The control’s client-side API is enabled if the ASPxDataViewBase.ClientInstanceName property is defined or any client event is handled.
