# Quick Start in ASP.NET AJAX
 
This topic demonstrates how to get started with ASP.NET AJAX Controls of Aurigma Graphics Mill 5.5 for .NET. It provides step-by-step instructions how to create a simple web application which loads and displays an image.
 
## Prerequisites
  
In addition to system requirements applied to Graphics Mill for .NET, ASP.NET AJAX Controls require to have **ASP.NET 2.0 AJAX Extensions 1.0** to be installed. You can download it from [http://go.microsoft.com/fwlink/?LinkID=77296↗](http://go.microsoft.com/fwlink/?LinkID=77296).
 
**Note** 
ASP.NET AJAX Controls can work only with ASP.NET 2.0. You cannot use it with earlier versions of ASP.NET.
 
## Getting Started
  
1. In Visual Studio 2005 create new ASP.NET AJAX-Enabled Web Site (menu File -> New Web Site...)
 
    ![Visual Studio Create New Web Site Dialog](https://www.graphicsmill.com/docs/gm5/AjaxControlsQuickStart1.png)
2. Add [BitmapViewer](https://www.graphicsmill.com/docs/gm5/T_Aurigma_GraphicsMill_AjaxControls_BitmapViewer.htm.md) AJAX control to the toolbox:

    - Right-click on the tab of toolbox where you want to add this control and select Choose Items....
    - Find the BitmapViewer in the .NET Framework Components tab.
    - If you cannot find this component, click Browse... and find the Aurigma.GraphicsMill.AjaxControls.dll assembly. Then click OK on both Open and Choose Toolbox Items dialogs.
 
        ![Visual Studio Choose Toolbox Items Dialog](https://www.graphicsmill.com/docs/gm5/AjaxControlsQuickStart2.png)
3. Open the necessary page (for example, Default.aspx) in the Design mode, then drag and drop the BitmapViewer control into the desired position.

4. Open the file which contains the code behind of this page (for example, Default.aspx.cs), and add the code which will load the sample image to the **Page\_Load** event handler:
 
```
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not Page.IsPostBack Then
            BitmapViewer1.Bitmap.Load(Server.MapPath("cat.jpg"))
        End If
    End Sub
    ```
 
```csharp
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            BitmapViewer1.Bitmap.Load(Server.MapPath("cat.jpg"));
        }
    }
    ```
5. Run the application (menu Debug -> Start Without Debugging or Ctrl+F5 shortcut). The page with the BitmapViewer control containing the image you specified on the last step will appear.
