State Management in Infopath Forms

lavssun — Mon, 23 Jun 2008 16:15:00 GMT

I'm currently working on a project that involves the modernization of lotus notes application to SharePoint-InfoPath stack. We are facing a scenario where we need to pass data between the two InfoPath forms Form A and Form B.

I was wondering whether InfoPath supports any form of state management. After a bit of research. the following blog post says it's feasible

The idea is to pass data as the Query String Parameter from Form A to Form B like the followinghttp://www.testsite.com/formb.xsn?param1a=1&param2a=2 In the code-beside of the Form B, we need to receive the parameters like the following. string bazValue = e.InputParameters["param1a"];string bizValue = e.InputParameters["param2a"];

Note:-

This works for browser InfoPath enabled 2007 forms too. VSTA (Visual Studio Tools for Application) needs to be used to wire the above logic inside the Form_Loaded event. I'm not sure whether this is the optimal way. If anyone has found a better way for InfoPath State management, please update me

Scenario

XMLFormView web part is used to render the Infopath browser forms. The XmlFormView web part cannot add to the web part page. It throws error message "The form has been closed"

Cause

This problem can be due to several reasons. They are listed below

The location ".xsn" might be hard-coded with an incorrect location
The XML FormView web part might be deployed to bin without sufficient code-access permissions

Solution

This can be solved by the following steps

Not to hard-code the .xsn location in the code-behind of XmlFormView web part
Provide the proper code-access permissions to the web part

Imports System.Security

<Assembly: AllowPartiallyTrustedCallers()>

After adding the web part to the web part page, provide the correct location of ".xsn" to the web part property
