I'm using ASP.NET MVC5 and I'm trying to create an EnumDropDownListFor
where :
Here is what I tried so far :
@Html.ListBoxFor(m => m.SelectedHeatingTypes, new SelectList(Model.HeatingTypeItems, "Value", "Text"))
@Html.ListBoxFor(m => m.SelectedHeatingTypes, Model.HeatingTypeItems, new { @class = "form-control" })
@Html.ListBoxFor(m => m.SelectedHeatingTypes, new MultiSelectList(Model.HeatingTypeItems, "Value", "Text"))
@Html.EnumDropDownListFor(m => m.HeatingTypes, new { @class = "form-control selectpicker", @multiple = "multiple"})
@Html.ListBoxFor(m => m.HeatingTypes, Model.HeatingTypeItems, htmlAttributes: new { @class = "form-control", multiple = "multiple" })
@Html.ListBoxFor(m => m.HeatingTypes, new SelectList(Enum.GetValues(typeof(HeatingType))), new { @id = "ddlMyEnum", @multiple = "multiple" })
On my model, I have thiese two properties
public IEnumerable<int> SelectedHeatingTypes { get; set; }
public IEnumerable<SelectListItem> HeatingTypeItems { get; set; }
I tried to change the IEnumerable<int> SelectedHeatingTypes
to int[]
, no more success
How can I bind the multi selection on a model property ? I'm open to Arrays, Lists, IEnumerable<>, everything I can work with server side...
I would check out KnockoutJs as that may solve your issue. That is a client-side binding, though, so you'd need to get your model to the client and then use KO to bind the data to your UI.
