Client-Side Events

Trace Events:

This example demonstrates the capabilities of our client-side event management technology. The DevExpress ASP.NET Timer (ASPxTimer) component has two client-side events - Init and Tick - which are traced and displayed in the Event monitor below the Download button.

In this demo, ASPxTimer is used to implement a countdown timer, and to temporarily disable the download button during the countdown. In the Init event's handler, the button is disabled, the value of the seconds counter is set, and specific descriptive text with a countdown is displayed. The Tick event is handled to decrease the seconds counter and to refresh the page's information when the specified time runs out.

To learn more about client-side events, refer to the Client-Side Events help topic.
