On intermittent occasions I get to work with PowerShell and in my last bout with the scripting language I ran across an amazing capability that really makes reading the output of PowerShell much easier – the Out-GridView cmdlet.  You can pipe the output of a command to Out-GridView and the results are displayed in an […]

SharePoint Apps: Blank Page Displayed when Navigating to App

I was trying to get a SharePoint app up and running in our environment but was running into a bit of an oddity.  After clicking on our App’s icon in Site Contents, I was taken to a blank page.  It wasn’t a SharePoint error page.  It wasn’t an IIS error page.  It was just a […]

IsObjectPropertyInstantiated vs. ServerObjectIsNull

0 comments

I was using the IsObjectPropertyInstantiated method off the Web class to determine if the AllProperties property on my Web instance was loaded.  I would expect that this would only return true if I have loaded AllProperties in some way, shape, or form using the ClientContext’s Load method.  However, that is apparently not the case. Let’s […]

Enabling Search Indexing on Property Bag Values in O365

0 comments

SharePoint allows you to store ad-hoc values in property bags values on SPWeb objects in server-side code.  You can even setup SharePoint search to crawl these properties using the server-side SPWeb.IndexedPropertyKeys property – just add the name of the property bag key to the list of IndexedPropertyKeys and the next time the crawler hits the […]
