# Server-side Programming Overview

Overview of the Server-side APIs you can use to create and configure the Telerik WebForms AIPrompt Control.

## Creating the AIPrompt in the Markup

To create an AIPrompt in the markup, add the `RadAIPrompt` element to the page and set its properties accordingly. You can find the properties in the following article:

* [Properties](https://www.telerik.com/products/aspnet-ajax/documentation/controls/aiprompt/server-side-programming/properties)

> caption Example: Create an AIPrompt in the markup

```ASP.NET
<telerik:RadAIPrompt runat="server" ID="RadAIPrompt1" Width="300px" />
```

## Creating the AIPrompt dynamically

To create the AIPrompt on the server, create a new instance of the `RadAIPrompt` object, set its properties and add it to the Controls collection of another control (e.g. `PlaceHolder1`).

> caption Example: Create an AIPrompt dynamically during PreInit

```C#
protected void Page_PreInit(object sender, EventArgs e)
{
    // Create dynamic controls during PreInit so they are restored on postback.
    RadAIPrompt aiPrompt = new RadAIPrompt()
    {
        Width = Unit.Pixel(400)
    };

    PlaceHolder1.Controls.Add(aiPrompt);
}
```

```VB
Protected Sub Page_PreInit(ByVal sender As Object, ByVal e As EventArgs) Handles Me.PreInit
    ' Create dynamic controls during PreInit so they are restored on postback.
    Dim aiPrompt As RadAIPrompt = New RadAIPrompt() With {
        .Width = Unit.Pixel(400)
    }

    PlaceHolder1.Controls.Add(aiPrompt)
End Sub
```

The `PlaceHolder1`

```ASP.NET
<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
```

> important Creating controls programmatically must be done in an early event such as **PreInit** (preferably), **Init**. For more details you can check out the [ASP.NET Page Life-Cycle Events](https://learn.microsoft.com/en-us/previous-versions/aspnet/ms178472\(v=vs.100\)#life-cycle-events)
