LinkedSelectList

Implements IEnumerable<LinkedSelectListItem>, evaluating a source object collection through DataBinder.Eval-driven value/text/linked-value field expressions to produce the items LinkedDropdownHelper renders.

Purpose

• Implements IEnumerable<LinkedSelectListItem>, evaluating a source object collection through DataBinder.Eval-driven value/text/linked-value field expressions to produce the items LinkedDropdownHelper renders.

Context

• Namespace: SAIF.Web.Mvc.UI.Extensions
• Assembly/package: SAIF.Framework.Web.Mvc (source-shipping NuGet package)
• Kind: class

Member	Signature	Purpose
LinkedSelectList(IEnumerable, string, string, string, IEnumerable)	public LinkedSelectList(IEnumerable items, string dataValueField, string dataTextField, string dataLinkedValueField, IEnumerable selectedValues)	Captures the source collection, the field-name expressions used to evaluate each item's value/text/linked-value, and the collection of currently-selected values; throws if items is null.
DataLinkedValueField	public string DataLinkedValueField { get; private set; }	Name of the field/property evaluated via DataBinder.Eval to produce each item's LinkValue.
DataTextField	public string DataTextField { get; private set; }	Name of the field/property evaluated via DataBinder.Eval to produce each item's Text.
DataValueField	public string DataValueField { get; private set; }	Name of the field/property evaluated via DataBinder.Eval to produce each item's Value.
Items	public IEnumerable Items { get; private set; }	The source collection whose items are projected into LinkedSelectListItems.
SelectedValues	public IEnumerable SelectedValues { get; private set; }	The collection of values compared (case-insensitively) against each item's evaluated value to determine selection; see BR-51.
GetEnumerator()	public virtual IEnumerator<LinkedSelectListItem> GetEnumerator()	Returns an enumerator over the internally computed LinkedSelectListItem list, delegating to the internal GetListItems() evaluation.

Behavioral notes

• The item-projection logic (DataBinder.Eval-driven evaluation and case-insensitive selection matching) lives in the internal GetListItems() method, which is not part of the public surface; it is reached only through GetEnumerator().
