To get the ASPxCardView‘s selection, use the ASPxCardView.Selection property. The object returned by this property provides methods that allow you to select and deselect individual cards or all cards, obtain the number of selected cards, etc.

ASPxCardView provides a comprehensive client-side API that enables you to manage a selection in the same manner as on the server side. These methods are listed in the following help topic: Member Table: Selections.

To respond to selection changes, handle the ASPxGridBase.SelectionChanged server event, or the ASPxClientCardView.SelectionChanged client event.

Example

In this example, the ASPxClientCardView.SelectionChanged client-side event is handled to display selected contacts within the list box. The ASPxClientCardView.GetSelectedFieldValues function is used to obtain contact names.

}
function GetSelectedFieldValuesCallback(values) {
    selectionList.BeginUpdate();
    try {
        selectionList.ClearItems();
        for (var i = 0; i < values.length; i++) {
            selectionList.AddItem(values[i].join(' '));
        }
    } finally {
        selectionList.EndUpdate();
    }
