BaseCollection<T>
Provides a state-managed generic collection base for RadMultiSelect related item collections.
Handles view state tracking for contained items that implement IMarkableStateManager.
Use this as a foundation for strongly-typed collections (e.g. MultiSelectItemCollection) that need:
- ASP.NET ViewState persistence
- Dirty-state propagation (so only changed items re-serialize)
- Familiar IList-like operations (Add / Insert / Remove / Contains / IndexOf)

Namespace:Telerik.Web.UI.MultiSelect

Append a single item to the end of the collection. Example:
items.Add(new MultiSelectItem("Text","Value"));public virtual void Add(T entity)Item to add (must not be null).
Append a sequence of items efficiently (avoids repeated caller loops).
Example: collection.AddRange(sourceList);
public virtual void AddRange(IEnumerable<T> entities)Enumerable of items to add.
protected virtual void Remove(T item)
