In this article, I will focus on a customization for Multi-list with Search. This scenario is not common. But sometimes you will need to customize a field in Sitecore. I will show you the steps that I followed to customize the Multi-List with Search.
Step 1: Prepare your component
I created a List View Component which contains multiple items.
This item will contains 2 fields:
- Title – Single-Line Text
- Description – Multi-Line Text
As we know, The Multi-List with Search by default shows the Item Name / Display Name, but as per client requirements we need to display and search using another field or even another item relation field.
Step 2: Create custom control
For this operation you can duplicate existing Multi-List with Search and name it “Custom Multilist with Search” or name that make sense to you.
Then, scroll down to Control Field and name something like “contentSpecificExtension:CustomMultilistWithSearch”
Step 3: Create custom Search.ashx Service and page load control class
Mutli-List with Search as you know it use Solr search to fetch the options. So in that case we will override search functionality to display the name as we required. Also we need to change the page load rendering to display the desired name.
Page Load Control Class
To create the class that will control the UI, we need to create a class named CustomMultilistWithSearch.cs
public class CustomMultilistWithSearch : BucketList
{
protected override string ScriptParameters => string.Format("'{0}'", (object)string.Join("', '", (object)this.ID, (object)this.ClientID, (object)this.PageNumber, (object)"/sitecore/shell/Applications/Buckets/Services/CustomSearchSearch.ashx", (object)this.Filter, (object)SearchHelper.GetDatabaseUrlParameter("&"), (object)this.TypeHereToSearch, (object)this.Of, (object)this.EnableSetNewStartLocation));
public override string OutputString(Item item)
{
Item bucketItemOrParent = item.GetParentBucketItemOrParent();
//string str = bucketItemOrParent != null ? " - " + bucketItemOrParent.DisplayName : string.Empty;
return item.Fields["Title"]?.Value;
}
}
In this script we are going to override ScriptParameters and noticed that is pointing to a CustomSearch.ashx file. And OuputString here we can add the code to display the desired name.
Then Website\sitecore\shell\Applications\Buckets\Services create a file which specified the class Handler that we are going to use to override the Search Behavior.
<%@ WebHandler="" Language="C#" CodeBehind="Search.ashx.cs" Class="Website.Areas.DemoSite.Infraestructure.CustomControls.Services.Buckets.Search" %>
Finally create a class Website.Areas.DemoSite.Infraestructure.CustomControls.Services.Buckets.Search.cs which contains the Search Logic
public class Search : IHttpHandler, IRequiresSessionState
