Prerequisite Knowledge
Views: Multi-surface Views Overview

The Cardflow™ 3D view, which is represented by the CardflowView3D class, provides a 3-dimensional card-view layout for the data items in a grid and allows various card "surfaces" to display data using customized, theme-defined surface configurations.

Surfaces

The Cardflow 3D view exposes different surfaces that can be configured to display data. These include the Left and Right surfaces, which are displayed on all cards located to the left and right of the center card, respectively, the Center surface, which is displayed on the front of the center card, and the Back surface, which is displayed on the back of the center card (see Figure 1 in Multi-surface Views Overview). 

The back surface of the center card can only be displayed if the IsCardFlippingEnabled property, which allows the center card to be flipped, is set to true.

Surface configurations can be provided by adding them to a multi-surface theme's SurfaceConfigurations collection (see Surface Configurations). The surfaces to which these configurations will be applied can then be specified by setting the CardflowView3D.Surfaces attached property on the configurations to the desired surfaces (see Example 1).

The following table provides a list of the surfaces configurations that are supported by the various multi-surface themes that support the Cardflow 3D view:

Card Positioning

In the Cardflow 3D view, cards are laid out in a 3-dimensional viewport, meaning that they can be positioned along the X, Y, and Z axes. The card groups located to either side of the center card can be offset from the middle of the center card through the SideCardsXOffset and SideCardsZOffset properties. Changing the X or Z side-card offsets results in the side cards being moved along the corresponding X or Z axis. Offsets are measured in card widths, meaning that an offset of +1 on the Z axis will cause the side-cards to move 1 card width forward (see Figure 2).



Figure 2: Side-card X and Z axes

Figure 3: X- and Y-angle rotations

The SideCardsXSpacing and SideCardsZSpacing properties indicate, in card widths, the X- and Z-axis spacing between the side cards; however, the spacing between the center card and the immediate left and right side cards will not be affected (see the SideCardsXOffset and SideCardsZOffset properties). The X- and Y-angle of the side cards can also be changed through the SideCardsXAngle and SideCardsYAngle properties, which will rotate the cards around the corresponding X or Y axis (see Figure 3). The same angle modifications can also be made to the center card by changing the values of the CenterCardXAngle and CenterCardYAngle properties.

The 3D Views sample application and Designer (Configuration Window) offer a variety of predefined card and camera settings that can be exported and used as implicit CardflowView3D styles in a resource dictionary.

The maximum number of cards that are displayed to both the left and right of the center card is determined by the SideCardsCount property. Cards that are in the viewport but outside the side-card range will not display a surface but rather the brush specified through the EmptySurfaceBrush property will be applied (see Example 2). When the "empty" cards are brought within range, the appropriate surface will be applied. When cards exit the specified range, their surfaces will be "removed" and the empty-surface brush will be used.

Cards have reflections that can be removed by setting the ShowReflections property to false (see also Tips for 3D Performance).

The physical card size in relation to the height of the viewport can be modified through the CardHeightToViewportRatio property, which, by default, specifies that the cards are 75% of the viewport's height. For example setting this property to 1 will result in the cards occupying the full height of the viewport, while a value of 2 will result in the cards being twice the height of the viewport.

Examples

All examples in this topic assume that the grid is bound to the Employees table of the Northwind database, unless stated otherwise.

Example 1: Providing surface configurations

The following example demonstrates how to provide an image and title surface configuration that will be applied to the center surface and a title surface configuration that will be applied to the left and right side cards.

Copy Code 
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">

                        If a data item contains more than one image you can set the FieldNames

                        property of the ImageRegionConfiguration to the name of the field that

                        contains the desired image. -->
