How to show a pop-up in SharePoint

This ages old trick deserves to be published – since it makes it easy to quickly show info from pretty much any another page on pretty much any classic SharePoint page (in a SharePoint-compatible pop-up). So, here goes: Using SharePoint’s JavaScript library to open an arbitrary pop-up Yes – SharePoint contains all the functionality out-of-the-box, and you almost don’t have to do anything yourself!

Using PowerShell to set ULS logging level to “extra verbose” to catch all the events in the logs

This blog post describes how set the SharePoint’s ULS level to “Extra Verbose” (VerboseEx) using PowerShell. This is not possible using the browser UI, so some POSH magic is required! Luckily, it’s quite straightforward, but to avoid filling your hard drive(s) with huge log files, you should reset the level when you’re done debugging! Description of the solution By default, ULS logging is somewhat non-detailed. This means that a lot of data that could be used to debug issues is omitted. The UI cannot be […]

Using PowerShell to modify anonymous access permissions on SharePoint On-Premises

Operation fails with the following (or similar) error: Error: Cannot uninstall the LanguagePack 0 because it […]

Malformed web.config causing a Parser Error

“Server Error in ‘/’ Application” or “Parser Error” – it’s actually a malformed web.config killing your ASP.NET-application or SharePoint

This post describes how to resolve a kind of cryptic and oddly misdescriptive error message about Parser Error on your ASP.NET application or (an On-Premises) SharePoint site. I ran into this after deploying wsp-packages to a SharePoint farm, but you can apparently get this on ASP.NET MVC sites, too. The error doesn’t actually tell you what’s wrong, so figuring it out took a while. Hopefully it’ll help you, though! Symptoms: Parser Error from a random-looking location Once you navigate to your web- or SharePoint site, you only […]

Visual Studio 2010 fails to show the design view of an aspx-page

Solution To download all deployed farm solutions (wsp-packages) from a SharePoint farm is pretty simple using PowerShell. No need to download individual packages through cumbersome interfaces! You don’t even have to open […]
