The CE Web Form Renderer is an ASP.NET Web Custom Control which, when dropped on an ASP.NET page, provides capabilities for customizing the rendering of Ispecs in the browser. The CE Web Form Renderer acts as a container for displaying so-called ASP.NET Web User Controls. The ASP.NET Generator generates the Ispec forms as ASP.NET Web User Controls which are then displayed on the web page by the CE Web Form Renderer. The CE Web Form Renderer acts as a container for the Ispecs. The web page on which the CE Web Form Renderer is dropped is designed and developed by the user. Compared with the ASP Generator, which generates a complete web page for each Ispec form, the CE Web Form Renderer control provides a much higher level of customization as users are in control of the design and behavior of the web page on which the Ispecs are displayed.
The web page delivered with the ASP.NET Generator is a default page which provides a standard basic interface to the Ispecs. Users who want to customize the page can modify the default page or develop their own and drop the CE Web Form Renderer on that.
The CE Web Form Renderer Control provides an interface that allows the hosting web page to control the rendering of the Ispec Web User Controls.
This interface allows:
Automatic connection to the runtime using properties set on the control at runtime or design time.
Rendering of the Generated Ispec Web User Control Forms.
Interception of events during the rendering process. These events include:
StatusLine event
PreTransaction event
PostTransaction event
ViewRestored event
SessionClosed event
WebSessionTimeOut event
HostConnect event
Using events, data entered by the user can be validated, a transaction can be cancelled, rendering Ispecs can be stopped/ resumed and display attributes of fields can be modified.
Handling of user clicking on the browser back or forward buttons.
