InfoPath Dev

I have an optional section in my form which is hide by default!

How can I Show it by C# code???

Go to the Optional section properties and select "Include this section in the form by default" checkbox. This will show the Optional section by default in the view.

You didnt understand my question.
I dont want the section to be shown! I want it to be shown only aftrer any change in me form. I want to display the section from the code on event in my form.

If a node is an optional in the xml and in the Infopath UI then then that node will not be present in the XML by default. You can add this node in the code, when you add this node in the code that optional field will be seen in the UI.

Here is the sample to add a Node
string sXml = "<my:group1 xmlns:my='http://schemas.microsoft.com/office/infopath/2003/myXSD/2005-04-13T11:32:39'><my:field1/></my:group1>";
IXMLDOMDocument oXml = thisXDocument.CreateDOM();
oXml.async = false;
oXml.loadXML(sXml);
getNode("//my:myFields").appendChild(oXml.documentElement);

I want to present all section and not only specific node in the section. My section contan table with fileds and text.

In the above example that i have give note that "<my:group1>" is a section which contains a node within it. Similarly you can have your fields inside that xml.
