  • 0

I have 2 list boxes which exchange items between them. I am doing this using javascript.
Im adding the items of the first listbox from the view. If I want to bind it from the model, what should I do? I have these properties in my model

    public List<ICode> UnAssignedStates { get; set; }
    public List<ICode> AssignedStates { get; set; }

where ICode is as below

    public interface ICode
{
    int Id { get; set; }
    ICodeGroup CodeGroup { get; set; }
    string ShortDescription { get; set; }
    string LongDescription { get; set; }
}

My view is as below

<table style="width:90%;  text-align:center">
        <thead>
            <tr>
                <th>Unassigned State:</th>
                <th></th>
                <th>Assigned State:</th>
            </tr>
        </thead>

    Assuming you are using Razor for your view engine replace the following

    <select id="box1View" multiple="multiple" style="height:100px;width:250px;">
                        <option value="501649">Item1</option>
                        <option value="501497">Item2</option>
                        <option value="501053">Item3</option>
                        <option value="500001">Item4</option>
                        <option value="501227">Item5</option>
                        <option value="501610">Item6</option>
</select>

    with:

    @Html.ListBox("box1View", new SelectList(Model.UnAssignedStates, "Id", "ShortDescription"), new {style = "height:100px;width:250px;"})

    and replace

    <select id="box2View" multiple="multiple" style="height:100px;width:250px;"></select>

    with:

    @Html.ListBox("box2View", new SelectList(Model.AssignedStates, "Id", "ShortDescription"), new {style = "height:100px;width:250px;"})
