Development using InfoPath: Part II

Layouts:

This panel will have few layout templates

Controls:

This section consist of the InfoPath supported controls

Data source:

Primary and secondary data source will be shown here so you can drag them in to design

Design Checker:

Design checker help to check the design compatibility and data source error its simply like compiling the form

Publish form template:

This help in publishing the form to SharePoint, E-mail, Network Location or installable Form template (output will be MSI package and can be installed in server and client machine).

Business Logic

 

Development using Visual studio:

Before starting development using Visual studio we need some pre-requisition to be installed.

Setting the default coding language

InfoPath supports using either JScript or VBScript in a form, but you cannot mix the two programming languages in a single form. To set the default scripting language used in a form, click Form Options on the Tools menu in design mode. In the Programming category of the Forms Options dialog box, select the programming language in the Programming language list.

Creating an event handler

When writing scripting code in an InfoPath form, you will usually be writing code in one of the InfoPath form or data validation event handlers. How you create the event handlers depends on the type of event that you want to use. It is important that you initially create the event handlers in design modeâ€"InfoPath creates the declarations of the event handlers in the script file and makes entries in the form definition (.xsf) file that enable a form to use the event handlers.

The following table lists each of the InfoPath event handlers and the steps for creating them.
