If the scope is "context", you could set the key's value as the following:
InfoJetContext jetContext = new InfoJetContext();
jetContext.Variables["SomeKey"] = "Value";
InfoJetForm form = null;
form = InfoJetService.BuildFormByTemplate(Context,jetContext,PublishUrl);
or:
form = InfoJetService.BuildFormByXML(Context,jetContext,PublishUrl,xml);

If the refresh attribute is "template", the cached data will be updated while the form template is registered, and if it is "form", the data will be refreshed while one form is opened or the data connection is queried in the form rules or form codes.
If two form templates use the same data connection, the key attributes should be the same also.

   InfoJet_UpdateFormFieldByDOMNode( field1 );
   return false;
]]>
</ClientScriptButton>

The input textbox binding my:field1 will be converted to a password field.
