Default Item in Dropdown for Custom List

[Emily]

I have a Target field in my PopupEditor that's using custom List to display a dropdown in the View. I want the first item in the custom list (Self) to show as the default value in the dropdown.

View:

@Html.LabelFor(model => model.Target, new { @class = "col-sm-5 control-label" })
<div>
    @Html.EditorFor(model => model.Target)
</div>

Controller:

public ActionResult Index()
{
    ViewData["Targets"] = ixList.Targets();

    return View();
}

Custom List (ixList):

public static List<TargetsModel> Targets()
{
    List<TargetsModel> targets = new List<TargetsModel>();

    targets.Add(new TargetsModel { Description = "Self", Target = "_self" });
    targets.Add(new TargetsModel { Description = "Blank", Target = "_blank" });

    return targets;
}

Model:

[UIHint("GridForeignKey")]
public string Target { get; set; }  // target = _blank, _self

 

How would I go about setting the first item Self to the default value? Right now the default value appears to be null.

Hi Emily,

You achieve the desired behavior by setting the default value directly in the Grid DataSource by passing the first item from the ViewData array of "Targets":

.DataSource(dataSource => dataSource
    .Ajax()
    .ServerOperation(false)
    .Model(model => {
        model.Id(p => p.ID);
        model.Field(p => p.ID).Editable(false);
        model.Field(p => p.Target).DefaultValue(((List<TargetsModel>)ViewData["Targets"])[0].Target);
