Question

I am looking for detailed ASP.NET MVC examples which make extensive use of grouped checkboxes (where multiple checkboxes can be selected, use case: choose the magazines you want to subscribe to with options such as “SI”, “Forbes”, “Money” etc) as well as grouped radio buttons (use case: at a bank choose either “savings” or “checking” account).

I have searched and found only scattered UI snipped but no complete MVC example which makes heavy use of these two UI elements and goes into detail on how the values from these elements are processed in the controller, captured in the model and persisted in the database.

Thanks,

The example here is for HTMLHelper for Checkbox Grouping

 public static class HtmlHelperGroup
{
static string container = @"<div id=""{0}"">{1}</div>";
static string checkboxhtml = @"<input type=""checkbox"" name=""{0}"" value=""{1}"" {3} />{2}</br>";


public static string CheckBoxGroup(this HtmlHelper obj, string name, List<SelectListItem> data)
    {
        StringBuilder sb = new StringBuilder();
        foreach (var content in data)
        {
            sb.Append(string.Format(checkboxhtml, name, content.Value,content.Text, content.Selected ? "checked" : string.Empty ));
        }
        return string.Format(container, "container_" + name, sb.ToString());
    }

}


<%=Html.CheckBoxGroup("account", new List<SelectListItem>() 
{
 new SelectListItem() { Text="Checking", Value = "1"  },
new SelectListItem() { Text="Saving", Value = "2"  }}) %>

Hope this helps
