Call it &quot;IsNew&quot;, for example. It&#39;s default value is 1, but then you can switch it to 0 when the user submits. Based on that field, you can implement conditional formatting in your form, such as disabling the dropdown if IsNew = 0.</p><p>Good luck! <br /></p>https://www.infopathdev.com:443/forums/thread/75763.aspxMon, 27 Feb 2012 20:14:07 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:75763Glebron0https://www.infopathdev.com:443/forums/thread/75763.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=75763<p>I created&nbsp;Form with a drop-down picker that runs a Few rules and populates some fields. Creates the form upon submit but&nbsp;when the user reopens the form to update some&nbsp;data he or she is able to then choose&nbsp;another Number from the picker thus changing all the info.&nbsp; is there a way to lock the picker once the form has been submitted ? &nbsp;</p>
