Examples

The following code example demonstrates the use of the HelpMode property to display Help for a control in the same browser window. The first part of this example assumes the use of a custom control, TextDisplayWebPart, which is found in the Example section of the WebPart class overview.

The code example also includes an HTML page that contains fictitious Help content for the TextDisplayWebPart control. For this example to work, you must save the following code in a file named Textwebparthelp.htm and place it in the same directory of your site as the .aspx page.

<html>  
<head runat="server">  
    <title>Text Content WebPart Help</title>  
</head>  
<body>  
  <div>  
  <h1>Text Content WebPart Help</h1>  
  To make the WebPart control work...  
  </div>  
</body>  
</html>  

The final part of the example is a Web page that shows how to reference the TextDisplayWebPart control. Note that in the declarative markup, the HelpMode property value is set to Navigate, and the code also sets the value of the HelpUrl property to the name of the HTML file that contains the Help content. Load the page into a browser, and click the help verb on the verbs menu of the WebPart control.
