Client-Side API

DevExpress ASP.NET MVC extensions provide an advanced client-side API that enables you to combine server-side and client-side functionality.

The DevExpress MVC extensions provide client-side APIs that are implemented using JavaScript. Extension-relative assemblies (DLLs) include JavaScript files that implement an extension's client-side APIs as embedded resources.

Expanded Attach Scripts

You should attach script files that implement extensions’ client-side APIs to an application.

The DevExpress ASP.NET Project Wizard automatically attaches the JavaScript files to the application's Site.Master page if you use a DevExpress Project Template to create an MVC application. If you do not use a DevExpress project template, you need to manually attach necessary DevExpress client script files using the ExtensionsFactory.RenderScripts extension method within a view page's HEAD or BODY tag.

View (or Master Page) Code (ASPX):

View (or layout View) Code (Razor):

Expanded Extension's Available Client API

Set an extension's EnableClientSideAPI (or Properties.EnableClientSideAPI) property to true to make the extension's client-side API available for developers. If a DevExpress MVC Extension does not provide the EnableClientSideAPI property, its client-side API is always available for this extension on the client side.

Note that an extension's client-side API is automatically available if you handle any of its client-side events.

Expanded Access an Extension on the Client Side

Use the SettingsBase.Name property to specify an extension's name to access its client object.

View code (ASPX):

View code (Razor):


Refer to the KA18687 KB article for information on how to access an extension's client object if the SettingsBase.Name property contains special characters (for example, the "." dot).

Expanded Client-Side Events

Each DevExpress ASP.NET MVC Extension provides a set of client-side events. Use the ClientSideEvents property at the level of the extension's settings (Settings.ClientSideEvents) or properties (Properties.ClientSideEvents) to access the available client-side events.


Register JavaScript functions at the top of the page. In this case, the browser executes these scripts before it renders the DevExpress ASP.NET MVC extensions.

The following code demonstrates how to handle an extension's client-side events:
