An important note here is that this post will only work if the InfoPath forms are deployed into the same directory as the feature.xml file. The feature receiver class referenced in it's FeatureInstalled() implementation only looks for XSN files in the features root directory.
If you place your XSN files into a seperate directory, then you will need to:
1. Add a custom property to your feature.xml that hints where the InfoPath forms are
deployed to. For example:
<Properties>
<Property Key="InfoPathFormsFeatureRelativeDirectory" Value="InfoPath\*.xsn"/>
</Properties>
2. Write and register your own/custom feature receiver.
+ In your feature receiver FeatureInstalled() implementation:
- Use the custom property to generate a list of fully qualified file names of your
InfoPath forms (see function EnumerateInfoPathFormTemplates below).
- Once you have the list of InfoPath forms, call Micosoft.Office.InfoPath.Server.Administration.FormTemplateCollection.RegisterFormTemplate function (located in Microsoft.Office.InfoPath.Server.dll) for each of your InfoPath forms to make them available on your SharePoint instance.
+ In your feature receiver FeatureUninstalled() implementation:
- Use the custom property to generate a list of fully qualified file names of your
InfoPath forms (see function EnumerateInfoPathFormTemplates below).
- Once you have the list of InfoPath forms, call Micosoft.Office.InfoPath.Server.Administration.FormService.FormTemplates.UnregisterFormTemplate function (located in Microsoft.Office.InfoPath.Server.dll) for each of your InfoPath forms to remove them from your SharePoint instance. To get an instance of the FormsService, do the following:
FormsService formsService = SPFarm.Local.Services.GetValue<FormsService>("");
Doing all this will make all your InfoPath forms available.
private static List<String> EnumerateInfoPathFormTemplates(SPFeatureDefinition featureDefinition)
{
SPFeatureProperty property =
featureDefinition.Properties[PreRegistrationInfoPathFormsReceiver.InfoPathFormsFeatureRelativeDirectory];
if ((property == null) || (String.IsNullOrEmpty(property.Value)))
{
throw new ArgumentException("Invalid InfoPath forms location specified.");
}
FileInfo[] infoPathFileInfos =
new DirectoryInfo(featureDefinition.RootDirectory).GetFiles(property.Value);
List<String> infoPathFormFileSpecs = new List<String>();
foreach (FileInfo fi in infoPathFileInfos)
{
infoPathFormFileSpecs.Add(Path.Combine(fi.DirectoryName, fi.Name));
}
return infoPathFormFileSpecs;
}
