#### Using the Form Designer

If you’re using the Form Designer, enable AJAX mode by opening the **Form configuration** panel and checking **Enable AJAX mode** on the **General** tab.

> **Note:** AJAX mode is available in the Form Designer as of WorkflowGen version 6.0.

#### Using Visual Studio

If you’re using Visual Studio to develop a custom ASPX form in AJAX mode, follow the instructions below.

1. In the `<form runat="server">` element, add a `ScriptManager` at the beginning of the form and wrap all the form content in the `contenttemplate` of an `UpdatePanel`.

2. Since standard `FileUpload` controls are not supported inside the `UpdatePanel`, use our custom `WorkflowFileUpload` user control for your attachment needs.

3. Add the following line in the page constructor to prevent an issue caused by WorkflowGen with the GridView when updating a row:

4. Register the postback triggers either in the `Page_Load` event or directly in the ASPX page.
