ASPxClientSpinEdit.NumberChanged Event

Occurs on the client when a user changes the editor’s value.

Declaration

NumberChanged: ASPxClientEvent<ASPxClientProcessingModeEventHandler<ASPxClientSpinEdit>>

Event Data

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

Property Description
processOnServer Specifies whether or not to process the event on the server.

Remarks

The NumberChanged event occurs when the editor’s value is changed by an end user typing in a new value, or by clicking any spin button.

Note

When an end user types in the editor’s text box, the editor value is not changed (and the NumberChanged event is not raised) until the value is confirmed by pressing the ENTER key, or by moving focus out of the editor.

Example

The following example calculates a summary in the CategoryID column based on the value in the ASPxSpinEdit below it.

When an end user changes a spin editor value, the editor sends a custom callback to the server in the client-side NumberChanged event handler. In the server-side SummaryDisplayText event handler, the grid calculates the summary value and sets it to the e.Text parameter.
