Remarks
The card view raises the CardLayoutCreated event for each data card when the corresponding card layout is created. You can handle this event to change card styles or settings based on cell values.
In addition to the event argument properties, you can use the FindLayoutItemByColumn(String) and FindLayoutItemOrGroup(String) methods to access and modify layout items or groups.
The following example illustrates how to use the FindLayoutItemByColumn(String) method to find a card’s layout items that belong to the specified columns. It also allows you to change these items’ visibility and column-span if the card is in edit mode.
protected void ASPxCardView1_CardLayoutCreated(object sender, ASPxCardViewCardLayoutCreatedEventArgs e) {
// Applies the card layout to the Edit Form only
if(e.IsEditingCard) {
ASPxCardView cardView = sender as ASPxCardView;
if(cardView.IsNewCardEditing) {
LayoutItem itemOrderID = e.FindLayoutItemByColumn(cardView.KeyFieldName);
itemOrderID.ClientVisible = false;
LayoutItem itemProductName = e.FindLayoutItemByColumn("ProductName");
itemProductName.ColumnSpan = 2;
}
}
