custom editor template are not setting correctly checkbox values

Question

I created an editor template for Boolean types, my problem it's when model attribute it's not nullable, the default behaviour of the checkbox are modified, for example if themodel value is true then the checkbox in the view appears without checked. What am I doing wrong??? this is the code.

@model Nullable<bool>

@{
    var listItems = new[]
    {   
        new SelectListItem { Value = "null", Text = "Sin Valor" },
        new SelectListItem { Value = "true", Text = "Si" },
        new SelectListItem { Value = "false", Text = "No" }
    };  

}

@if (ViewData.ModelMetadata.IsNullableValueType)
{

    @Html.DropDownListFor(model => model.Value, listItems)
}
else
{
    @Html.CheckBox("", ViewData.TemplateInfo.FormattedModelValue)
}

Not sure what ViewData.ModelMetadata.v that you are using in your checkbox means. Have you tried:

@model Nullable<bool>

@{
    var listItems = new[]
    {   
        new SelectListItem { Value = "null", Text = "Sin Valor" },
        new SelectListItem { Value = "true", Text = "Si" },
        new SelectListItem { Value = "false", Text = "No" }
    };  
}

@if (ViewData.ModelMetadata.IsNullableValueType)
{
    @Html.DropDownList("", new SelectList(listItems, "Value", "Text", Model))
}
else
{
    @Html.CheckBox("", Model.Value)
}

This example shows in detail the implementation of boolean templates for a dropdownlist that contains Yes, No and Not Set values and also handles null bool values. Inspired from Darin Dimitrov and Jorge above - Thank you.

Model Student.cs

    [Display(Name = "Present:")]
    [UIHint("YesNo")]
    public bool? IsPresent { get; set; }

DisplayTemplates: YesNo.cshtml

@model Nullable<bool>

@if (Model.HasValue)
{
    if (Model.Value)
        { <text>Yes</text> }
    else
        { <text>No</text> }
}
else
    { <text>Not Set</text> }

EditorTemplates: YesNo.cshtml

@model Nullable<bool>

@{
    var listItems = new[]
    {   
        new SelectListItem { Value = "null", Text = "Not Set" },
        new SelectListItem { Value = "true", Text = "Yes" },
        new SelectListItem { Value = "false", Text = "No" }
    };  
}

@if (ViewData.ModelMetadata.IsNullableValueType)
{
    @Html.DropDownList("", new SelectList(listItems, "Value", "Text", Model))
}
else
{
    @Html.CheckBox("", Model.Value)
}

View:

    <div class="editor-label">
        @Html.LabelFor(model => model.IsPresent )
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.IsPresent )
        @Html.ValidationMessageFor(model => model.IsPresent )
    </div>
