Bug in Visual Studio 2010 and 2012 with implicit adding of elements into random feature in Sharepoint project templates

2013-06-01T00:12:00.001+04:00

If you used VS2010 for Sharepoint development you most probably encountered with the famous problem: when you add a new element (e.g. new module) to the project created using Sharepoint project template, VS implicitly adds this element to the randomly selected feature. Waldek Mastykarz even created extension for VS, which prevents this behavior: Mavention Cancel Adding SharePoint Project Items.

Provision list view web parts declaratively and modify their views in Sharepoint

2013-05-25T13:50:00.001+04:00

You may provision list views web parts as any other web part by adding it to Module > File > AllUsersWebPart in the feature’s element manifest. In this case you have to add xml declaration of the web part inside AllUsersWebPart (you may get it if e.g. will add list view web part on the page manually and then will export it to the file on disk). However there is more simple way to provision list

How to open Sharepoint sites running on development VMWare images on iPad, iPhone and other mobile devices

2013-04-18T02:24:00.001+04:00

In Sharepoint development we often use VMWare images for development environments. In most of the projects in my practice we used this model. It is useful when there are configured ready for use development images, so developers only need to get the image and start to work. But how we can test sites which are developed on the VMWare images on mobile devices? At the current moment role of mobile

Script for copying and archiving files to zip for making regular backups in cloud using built-in Windows features

2013-04-13T11:16:00.001+04:00

Often we need to backup some files on the servers on regular basis.

Managed metadata navigation and friendly URLs in Sharepoint 2013 – part 1

2013-03-30T12:17:00.001+04:00

Managed metadata navigation and friendly URLs is one of my favorite features in Sharepoint 2013. Finally we may get rid of /pages/default.aspx and live with SEO (remember that Google uses URLs in the ranking) and user-friendly URLs for pages and sub sites. This feature allows also to show content from different locations inside one site in Sharepoint, so end users even won’t actually know that it

Drawbacks of using search-driven approach in Sharepoint 2013

2013-03-28T01:15:00.001+04:00

On the SPC 2012 where Sharepoint 2013 was officially presented to the public (although it was release a few weeks before) one of the raised question was: why to not use search-driven approach? The idea of this approach is quite simple: there is authoring site where content owners create content. This site is not available for regular visitors. Content from authoring site is crawled by search

Custom Sharepoint jobs are not shown in the Sharepoint Central Administration

2013-02-17T11:41:00.001+04:00

Sharepoint jobs allows you to execute tasks by scheduler, similar to the way how standard Windows scheduler works. You may consider to move time consuming tasks to the job, so they will run asynchronously and won’t affect user experience (e.g. won’t cause Timeout exceptions because of long task processing during synchronous requests). Sharepoint jobs are executed in separate Windows process

Convert Visual Studio Sharepoint 2010 project to Sharepoint 2013 project

2013-02-17T01:00:00.001+04:00

Recently we performed migration of the several sites from Sharepoint 2010 to Sharepoint 2013. We have several standard Sharepoint 2010 Visual Studio projects (wsps) in solution which contain our customizations. As we didn’t find standard way of changing target platform in Visual Studio from Sharepoint 2010 to 2013, we created new empty Sharepoint 2013 project in Visual Studio 2012 and manually

ASP.Net Checkbox.Checked is set to default when use disabled attribute or difference between Enabled property and disabled attribute

2013-01-19T23:46:00.001+04:00

Update 2013-01-27: the problem described in this post is reproducible in IE9. In other browsers when you add disabled attribute to the Checkbox, user still may change the value and bug is not reproduced. Some time ago I faced with interesting behavior of ASP.Net Checkbox control, which confused me a bit. And I decided to dig into the problem in order to understand why it works like this.
