Today I came across a dangerous pitfall when working with Linq for SharePoint 2010. For those of you who are not familiar with it; there is a tool called spmetal you can use to generate a Linq DataContext class for your SharePoint site.

Ok so we’re building sandboxed solutions for SharePoint Online, great! Now suppose you’ve got your solution deployed and your customer starts working with it. All is well and of course they’re superpleased with you and start sending you gifts and stuff. But then, one day, you get a call: “hey, could you also add this

I came across this error when trying to deploy a sandboxed solution. The first step in the process is to retract the solution currently in the store, it there is one. That’s fine, but this caused an error. It took me some time to figure out what was happening, so perhaps this post will help

We have several claims based site on which we use Forms based authentication alongside Windows based authentication. The forms based users were regularly complaining that the “Remember me” checkbox “wasn’t working”.

On our intra- /extranet, we have a seperate section in which we allow our customers to log in. Each customer gets a private portal site to collaborate with us. Of course, we wanted to add a help section to help users with the usage of this site. For our internal users, we have a wiki

I want to summarize a few steps you need to take to deploy custom list forms (like NewForm.aspx) and view forms (like AllItems.aspx). Not because these things are undocumented, they are, but because I couldn’t find a good article which sums it all up in a neat way. So I’ll give that a shot myself

For a project I’m working on, I needed to make a distinction between user types. Not the default read / write things, which are default of course, but my own set. So I went looking and found the customizable Role Definitions. Basically, a custom role definition adds an option to the ‘manage rights’ section of
