Redirecting after using InfoPath Form (web-enabled) in Sharepoint 2007

1. Use the Source query string: so the page will know where to navigate to after the form is closed or submitted (Watch Out: The URL must be in the same site collection or an error will be returned.)
2. Add the OnClose event to the XmlFormView, add code to redirect after closing:
   Response.Redirect(http://www.dolmen.be);
   In the Infopath Form, you must add the Action: "Close this form: No Prompt" in the rules of the InfoPath Button, otherwise the OnClose event won't fire.

Query DataConnection in Infopath Web-enabled Form when selecting value of dropdownlost (with Managed Code)

You don't always need to load your dataconnection before the form is loaded (performance reasons), sometimes you want to load a different dataconnection when a certain value is selected. I use the example of a dropdownlist, and every value of the dropdownlist will load an other dataconnection into another dropdownlist.



Add the 2 dropdownlists, the second dropdownlist must have a connection with a datasource (I use an embedded Xml file dc.xml). When creating this dataconnection, please deselect the setting "Automatically retrieve dat when form is opened".




What you will need after you created the controls in infopath, open VSTA (alt+shift+F12). Add following code fragment into the InternalStartup method:

this.EventManager.XmlEvents["/my:myFields/my:Type"].Changed += new XmlChangedEventHandler(TypeChanged);

You also need to add the TypeChanged methods:

void TypeChanged(object sender,XmlEventArgs e)
{
  string type = e.NewValue; //the selected value of the type dropdownlist
  
  //I just added one dataconnection called dc (value when you select POST)
  //You need to put here code (switch) for all the values in the type ddl    
  DataSource ds = this.DataSources[type];
  DataConnection dc = ds.QueryConnection;

  dc.Execute();
}

When you use the Execute method of a dataconnection, you must change following setting (it is like the ASP.NET AutoPostBack setting), otherwise your dataconnection will not be loaded!! (when you just changed a value of another field, you don't need to change this setting).




Change the standard option (postback settings): "Only when necessary for correct rendering of the form (recommended)" to "Always"


Remarks:
When you use Mananged Code in web-enabled form, uou must publish it as an administrator approved template (check out blogpost http://spsfactory.blogspot.com/2007/01/walkthrough-publishing-administrator.html )
