Is it possible to detect if a host page is in edit mode? This solution works very fine if the app part is selected, but not if something else is edited on page.</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3573304" width="1" height="1">http://blogs.technet.com/b/sharepointdevelopersupport/archive/2013/02/04/how-to-detect-an-app-part-in-edit-mode-in-sharepoint-2013.aspx#3565182Wed, 10 Apr 2013 23:31:27 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3565182aaron<p>Thank you for pointing out. wpId is indeed redundant. It&#39;s built-in. The following part is not necessary in code.</p> <p> &nbsp; &nbsp;&lt;Property Name=&quot;wpId&quot;</p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Type=&quot;string&quot;</p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; RequiresDesignerPermission=&quot;true&quot;</p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; WebCategory=&quot;Basic app part category&quot;</p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; WebDisplayName=&quot;WebpartID&quot;</p> <p> &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DefaultValue=&quot;webpart ID&quot;&gt;</p> <p> &nbsp; &nbsp; &lt;/Property&gt;</p> <p>Checked your blog.

Your post have inspired me to do some research and find a few additional tokens (parameters) available for App Parts. Please check my blog post:</p> <p><a rel="nofollow" target="_new" href="http://blog.sharepointalist.com/2013/02/sharepoint-2013-app-part-tokens.html">blog.sharepointalist.com/.../sharepoint-2013-app-part-tokens.html</a></p> <p>PS. Also one correction. wpId custom property is completely redundant in this sample.</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3551381" width="1" height="1">http://blogs.technet.com/b/sharepointdevelopersupport/archive/2013/02/04/how-to-detect-an-app-part-in-edit-mode-in-sharepoint-2013.aspx#3550440Tue, 05 Feb 2013 13:12:52 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3550440Arun Kumar Arora<p>Very Informative.</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3550440" width="1" height="1">http://blogs.technet.com/b/sharepointdevelopersupport/archive/2013/02/04/how-to-detect-an-app-part-in-edit-mode-in-sharepoint-2013.aspx#3550209Mon, 04 Feb 2013 13:29:25 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3550209Waqas M<p>Thanks for sharing</p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3550209" width="1" height="1">
