Writing a component for parsing XML files with XMLSerializer I had to provide DTD validation (DTD file was already created long time ago so there was no sense for creating XSD schema). The component must have been able to work in console application and web app (as a SharePoint timer job) so there was no chance to guarantee the same paths for DTD file (which was always specified in doctype directive in processed files). In such situation I’ve decided to deliver the DTD file as embedded resource in component assembly.
For the years I have developed .Net projects I’ve found many useful solutions on CodePlex repository. Some of them are only drafts of ideas but there are also many products that are ready to use on production environments. SharePoint 2010 Batch Edit which worked with recently is one of this from the second category.
As the name suggests, SharePoint 2010 Batch Edit fills the gap in mass updates functionality in SharePoint 2010. In OOB SP2010 you can select one or more items on list view and perform such operations as check-in, check-out, delete an so on, but there is no tool that would allow to update items data for more than one item at once. Of course you can always write your own application page and display it in dialog box but why you should do this if someone already has done it :-)
Looking for some solution for batch items update I’ve run into the following problem: when I clicked a checkbox in top right corner of the list (actually a document library) “All Items” view, the browser displayed an error: You cannot select more than 100 items at once.
