Sitecore Module – Sitecore Child Item Count

Sitecore Child Item Count Module is for getting the child item of the selected item in Content Editor. It also provide an option to specify the template id of child item, if you want to fetch the items of any specific template. It works based on the index. It also check the current Language. If your current selected language is Japanese and if the child item doesn’t exist with Japanese language version than it won’t include in child count.

How to use Linq Lambda Expression IEqualityComparer For IEnumerable.Except

One of the thing that sometimes annoys is Lambda Expression with IEqualityComparer. I was trying to pick items with Except Comparer from the list. After doing quick search on google found the below extension method which can be used in such scenario. 

public static IEnumerable Except(this IEnumerable first, IEnumerable second, Func<TSource, TSource, bool> comparer)
{
return first.Where(x => second.Count(y => comparer(x, y)) == 0);
}

How to use:

List myItemsList = source.Except(myDeals, (x, y) => x.ID == y.ID).Take(requiredCount).ToList();

This will return the list of items except item(s) which match with an ID in myDeals.

Sitecore query with hypen or dashes

Challenge:

Sometimes your sitecore query might contains hypen or space and you get an error: “unterminated literal string in Query”. It is because the query contains an illegal character and the solution is to escape the “-“.So we need to add hash(#) around the word in the query.

Query: /sitecore/content/My Site/Event/ABC-Items

Earlier I referred the below article and implimented in one of the project:

Escaping dashes/“-” in Sitecore Queries. Datasource query Update

This is actually the nice example. But while working on another project, I applied below piece of code which I think is better and easy solution then the one given in above link.

Sitecore Experience Editor with different Site context

Challenge:

In Multi-Site Sitecore solution we allow user to load any site in Experience Editor with any Sitecore Site URL. We also provide an option to the user to create Sites on the fly. The problem we were facing was during Experience Editor. In Experience Editor you can make use of query string and get the Item based on sc_itemid. That was working absolutely fine. Now we provided an option to a user in Ribbon to change the color. Every Custom Site that user creates on the fly – each have their own fields to change the color.  We were not getting the correct site because Webutil was providing the below information.

Sitecore.Web.WebUtil.GetRawUrl(): “/-/speak/request/v1/expeditor/ExperienceEditor.GenerateFieldUrl”

Speak Request URL: http://sc8.com:80/-/speak/request/v1/expeditor/ExperienceEditor.GenerateFieldUrl

Now in this request you don’t get sc_itemid – we wanted to get the actual item id (sc_itemid) based on the current Site which user has loaded in Experience Editor, so that we can show/load the correct option to change the color.

Error: Could not load file or assembly Ninject

Challenge:

Error: Could not load file or assembly ‘Ninject, Version=3.2.0.0, Culture=neutral, PublicKeyToken=c7192dc5380945e7’ or one of its dependencies. The system cannot find the file specified.

Above error started appearing suddenly in our local Sitecore (Sitecore.NET 8.1 (rev. 151207)) project. We eyed lot of articles on-line but none helped, So that is why I thought it’s better to blog this out. We investigated for couple of hours to get this fixed, may be this post saves someone’s time.

Using AutoMapper

Challenge:

We defined the Web-Service and were using it in an application. Web-Service returns an object or list of an object.

 

There was already code written to do the processing once we get the response object from web-service.But when we get the object via web-service, it append the Web Service Reference Name because of which we were not able to utilize the already written code for processing that object. We believe in Re-usability as much as possible and wanted to re-utilize that code which was also used by other functions. Web-Service was returning lot of data which includes list and list of object inside the list etc.
