Client-Side Events

Trace Events:







This sample demonstrates the capabilities of our client-side event technology. All client-side events exposed by the DevExpress MVC Navigation Bar are traced in this demo. Click any item or expand/collapse a group within the NavBar to initiate client-side events.

Client-side events are triggered in response to specific actions or events on the client side (in particular, to expanding/collapsing a group). Client-side event handlers represent code written in JavaScript. In order to handle a client-side event, the sender web control provides a property that accepts either handling code directly or the name of a handling function. This function should be defined directly in the page's HTML code or in a separate js file. For each client-side event, there is a specific object, which has both server-side and client-side representations. This object will automatically render the necessary JavaScript code to the page and assign it as a handler to the web control on the client side.
