Gets or sets the name of the file that contains text for the body of the e-mail message.
Assembly: System.Web (in System.Web.dll)
The property specifies the location of the text file to use for the body of the e-mail message.
The CreateMailMessage(String, IDictionary, Control) method uses its owner parameter to map the property to a path on the server. If the owner parameter points to a control on an .aspx page or to the page itself, the property points to a text file in the same directory as the .aspx page. For example, if the .aspx page is located at C:\inetpub\wwwroot\default.aspx, the MailDefinition control looks for the text file in the directory C:\inetpub\wwwroot.
If the MailDefinition class is used in a user control contained in an .ascx file, the property points to a text file located in the same directory as the user control. For example, if the .aspx page is located at C:\inetpub\wwwroot\default.aspx and the user control is at C:\inetpub\wwwroot\controls\control.aspx, the MailDefinition object looks for the text file in the directory C:\inetpub\wwwroot\controls.
