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.

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

In Visual Studio 2005 create new ASP.NET AJAX-Enabled Web Site (menu File -> New Web Site...)
Add BitmapViewer 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.
Open the necessary page (for example, Default.aspx) in the Design mode, then drag and drop the BitmapViewer control into the desired position.

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:

Visual Basic

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

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        BitmapViewer1.Bitmap.Load(Server.MapPath("cat.jpg"));
    }
}

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.
