# ColumnCreated

The **RadGantt ColumnCreated** is fired after a [TreeList](https://www.telerik.com/products/aspnet-ajax/documentation/controls/gantt/layout) column was created.

**ColumnCreated** event handler receives two parameters:

* **sender** is the **RadGantt** control instance.

* **e** is an object of type **ColumnCreatedEventArgs**. It gives you access to the created [TreeList](https://www.telerik.com/products/aspnet-ajax/documentation/controls/gantt/layout) column.

## Example

```ASP.NET
<telerik:RadGantt RenderMode="Lightweight" ID="RadGantt1" runat="server" OnColumnCreated="RadGantt1_ColumnCreated"></telerik:RadGantt>
```

```C#
protected void RadGantt1_ColumnCreated(object sender, Telerik.Web.UI.Gantt.ColumnCreatedEventArgs e)
{
    //...
}
```

```VB.NET
Protected Sub RadGantt1_ColumnCreated(sender As Object, e As Gantt.ColumnCreatedEventArgs)
    '...
End Sub
```
