ASPxCardView.CardInserted Event

Fires after a new card has been added to the ASPxCardView.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v23.2.dll

NuGet Package: DevExpress.Web

Declaration

C#

public event ASPxDataInsertedEventHandler CardInserted

VB.NET

Public Event CardInserted As ASPxDataInsertedEventHandler

Event Data

The CardInserted event's data class is ASPxDataInsertedEventArgs. The following properties provide information specific to this event:

Property	Description
AffectedRecords	Gets the number of records affected by the update operation. Inherited from ASPxDataBaseUpdatedEventArgs.
Exception	Gets the exception (if any) that was raised during the update operation. Inherited from ASPxDataBaseUpdatedEventArgs.
ExceptionHandled	Gets or sets whether an exception raised during the update operation was handled in the event handler. Inherited from ASPxDataBaseUpdatedEventArgs.
NewValues	Gets a dictionary that contains the values of the non-key field name/value pairs in the row to be inserted.

Remarks

End-users can create new cards by clicking the New command. To create cards in code, use the ASPxCardView.AddNewCard method. To save the newly created card, end-users must click the Update command.

To cancel the insert operation, handle the ASPxCardView.CardInserting event.

Note

The CardInserted event fires even though an exception occurs during the data update operation. Use the ASPxDataBaseUpdatedEventArgs.Exception and ASPxDataBaseUpdatedEventArgs.ExceptionHandled argument properties to determine whether or not any exception occurs during the corresponding action, and handle it if you wish.

Example

The code sample below demonstrates how to focus a newly inserted card. Handle the CardInserted event to get a key value of the card. Call the FindVisibleIndexByKeyValue(Object) method to get the card’s visible index. Then set the FocusedCardIndex property.
