Public Function GenerateSelect (viewContext As ViewContext, modelExplorer As ModelExplorer, optionLabel As String, expression As String, selectList As IEnumerable(Of SelectListItem), allowMultiple As Boolean, htmlAttributes As Object) As TagBuilder

Parameters

viewContext
ViewContext

A ViewContext instance for the current scope.

modelExplorer
ModelExplorer

ModelExplorer for the expression. If null, determines validation attributes using viewContext and the expression.

optionLabel
String

Optional text for a default empty <option> element.

expression
String

Expression name, relative to the current model.

selectList
IEnumerable<SelectListItem>

A collection of SelectListItem objects used to populate the <select> element with <optgroup> and <option> elements. If null, finds this collection at ViewContext.ViewData[expression].

allowMultiple
Boolean

If true, includes a multiple attribute in the generated HTML. Otherwise generates a single-selection <select> element.

htmlAttributes
Object

An Object that contains the HTML attributes for the <select> element. Alternatively, an IDictionary<TKey,TValue> instance containing the HTML attributes.

Returns

TagBuilder

A new TagBuilder describing the <select> element.

Remarks

Combines HtmlFieldPrefix and expression to set <select> element's "name" attribute. Sanitizes expression to set element's "id" attribute.

See GetCurrentValues(ViewContext, ModelExplorer, String, Boolean) for information about how current values are determined.
