Get access to edit sealed, read only columns in SP2010
When using SharePoint content migration software this is really useful because if the column is read-only and sealed you can't write to it! (Unless you do a few tricks... )
Using SharePoint Management Shell (2010):
#Get the web, list and column objects<br /> $web = Get-SPWeb $list = $web.Lists[""] $column = $list.Fields[""] #Change the readonly and sealed properties and update objects $column.ReadOnlyField = $false $column.Sealed = $false $column.Update() $list.Update() #Give us the new column settings for our reference $column $web.Dispose()
