Hi,

 I have an section control on my page & I need hide id based on some condition. I have implemented below code for hiding section control

 CurrentView.ExecuteAction(ActionType.XOptionalRemove, "EULA");

But while executing that I get the followign error. The fieldname of the section is "EULA"

System.NotImplementedException: The method or operation is not implemented.
at Microsoft.Office.InfoPath.Server.DocumentLifetime.ViewHost.ExecuteAction(ActionType action, String xmlToEdit)
at ExternalAccountForm.FormCode.FormEvents_Loading(Object sender, LoadingEventArgs e) in D:\Inetpub\WWWROOT\InfoPath\Forms\ExternalUser\FormCode.cs:line 199

An entry has been added to the Windows event log of the server.

What might be the issue?

What code are you using to hide it? What happens around line 199? Have you tried hiding it using conditional formatting and rules i.e. not through code? 

I use below code

XPathNavigator node = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:OptionalEULAGroup", NamespaceManager);
CurrentView.SelectNodes(node, node, "CTRL82");
CurrentView.ExecuteAction(ActionType.XOptionalRemove, "group1_154");

My requirement is to hide this section on Edit mode of the form & display it on insert mode. So in that case I do not use the rules & conditions

BTW Can I only use Optional Section control for such a requirement?

Can you tell us a little about the parameters you use in your code?

XPathNavigator node = MainDataSource.CreateNavigator().SelectSingleNode("/my:myFields/my:OptionalEULAGroup", NamespaceManager);
CurrentView.SelectNodes(node, node, "CTRL82");
CurrentView.ExecuteAction(ActionType.XOptionalRemove, "group1_154");

According to http://msdn.microsoft.com/en-us/library/aa945763.aspx
The first two parameters of your SelectNodes method should be a start and end node, yours are both the same. Is this correct? Also, what is CTRL82? Is it the same as OptionalEULAGroup?

On your last line what is the contents of group1_154?

This is the only way I know of.

CTRL82 is the ViewContext name (if you right click the Optional section control -> Advanced tab)

OptionalEULAGroup is the name of the field / group name

group1_154 is the value of XmlToEdit For XOptional field (if you right click the Optional section control -> Advanced tab)
