Sitecore Multi list Code Data Source




Recently, in my project, I had a requirement where, I had to show Items in a list dynamically based on its parent, and we are currently using Multi list with search,

and I found it's better to use a custom data source as the query and fast query doesn't work for my case,

so, I used the "code" Data source as it's the best solution for my case

Below is an example of how I implemented this approach:

    Case:

    My case was to map the department with it's company,
    so I put the path of the company on the parent of the department

    Code:

    firstly, you have to add reference for Sitecore.Bucket.dll as we will implement IDatasource interface 
        
    public class DepartmentCustomDataSource : IDataSource
    {
        public Item[] ListQuery(Item item)
        {
            // department company
            Item parent = item.Parent;
            string departmentLink = parent[Templates.CompanyDepartment.Fields.DepartmentMapping];
            var database = Sitecore.Context.ContentDatabase;
            var erpCompany=database.GetItem(departmentLink);
            var erpDepartments = erpCompany.Children.ToArray();
            return erpDepartments;
        }
    }

    CMS:

    in the source of your Multi list field put it the below format

    code:"your class namespace with method", "dll name"

    C# Numeric types Overflow

    will this code be compiled? int x= int.MaxValue; x=x+1; The answer is, yes it will be compiled  I will tell you how, at runtime arithmetic operations on Integral types can overflow, and this happens silently no exceptions will be thrown, and the results exhibits wraparound behavior that means  int x= int.MaxValue; x= x+1; (x == int.MinValue) // True and if we do also the below expressions it will not give you the right result int a = 80000;  int b = 80000;  int c = a * b;  // 2105032704 while the right result is  6,400,000,000 So to avoid this issue we will use Checked Operator int a = 80000;  int b = 80000;  int c = checked(a * b);  // Run-time exception (line 9): Arithmetic operation resulted in an overflow Checked: The checked keyword is used to explicitly enable overflow checking for integral-type arithmetic ...
