# Client-side Programming Overview

**Gantt** provides a flexible client-side API. You can easily interact with RadComboBox in the browser using its client-side object.In addition to a variety of [client-side events](https://www.telerik.com/products/aspnet-ajax/documentation/controls/gantt/client-side-programming/events/overview), the client-side object model lets you achieve complicated tasks whileavoiding unnecessary postbacks.

## Getting the Gantt Client-side Object

**Gantt** creates a client-side object with its **ClientID**. You can obtain the reference using the following JavaScript code:

```JavaScript
var gantt = $find("<%= RadGantt1.ClientID %>");
```

## Getting the Instance of a Particular Gantt Task

Getting instance of a particular task using the **Gantt's** client API:

```JavaScript
var gantt = $find("<%= RadGantt1.ClientID %>");
var tasks = gantt.get_tasks();
var task = tasks.getTask(0);
```

## Getting the Instance of a Particular Gantt Dependency

Getting instance of a particular dependency using the **Gantt's** client API:

```JavaScript
var gantt = $find("<%= RadGantt1.ClientID %>");
var dependencies = gantt.get_dependencies();
var dependency  = get_dependencies().getDependency(0);
```

## Cancelling an Event

Several client-side events occur immediately before **Gantt** performs some action. Most of these events all have names that end with "-ing".You can use these events to cancel the **Gantt**'s action by using the **set_cancel** method of the **eventArgs** passed tothe handler:

```JavaScript
function OnClientTaskResizing(sender, eventArgs) {
    eventArgs.set_cancel(true);
}
```
