The DevExpress ASP.NET Card View (ASPxCardView) allows end-users to select cards with a simple mouse click. To enable this selection mode, set the SettingsBehavior.AllowSelectByCardClick property to true. Once set, clicking any cards clears the previous selection and selects this card.
To select multiple cards, click the desired cards while holding down the CTRL key, or click a card's check box. Clicking a card in this manner toggles its selected state and preserves the selection. To select contiguous cards, click the first card you wish to select, hold down the SHIFT key, and click the last card. You can continue to customize selection by clicking individual cards while holding down the CTRL key.
