Save Web-based InfoPath form with the title as its file name

Question

How do I save a new web-based InfoPath form without having to manual-type the file name in the Save As dialog box as shown below:

The 'Name' column, which represent the File name can be derive from other column of the form. (Assuming all column of the forms need to be filled up).

Example:
In the form, there are 3 column named - Book_Title, Book_Author, Book_Price.
When a user create a new item in the form and provide the following information:
Book_Title: JQuery
Book_Author: Anderson
Book_Price: USD 10
After the user have typed finish, the user click save and SharePoint immediately name the File name as "JQuery_Anderson" and auto-close the form.

Answer 1

You can solve this by adding custom save/submit button to your form.

• Custom Save Button for Web Enabled Form
• Custom Save and Submit Buttons for InfoPath Browser Forms

Answer 2

Or use a workflow after the fact, build a dynamic string storing Book Title and underscore and the Book Author. Then update the title with that value.
