How do i create a display template so i can display a bool as Yes or No not a checkbox? Using mvc3
<%: Html.DisplayFor(model => model.SomeBoolean)%>
I had to create something similar so it would display "Sim" and "Não" (portuguese Yes/No). I created the following file:
Views\Shared\DisplayTemplates\Boolean.ascx
And added the following code:
<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<dynamic>" %>
<%= (bool) ViewData.Model ? "Sim" : "Não" %>
Hope this helps!
EDIT Forgot, in your view, simply call it like so:
<%= Html.DisplayFor(i => item.Ativo) %>
EDIT 2 For a nullable (bool?), try this:
<%= (ViewData.Model == null) ? "NA" : (ViewData.Model == true) ? "Y" : "N"%>
EDIT 3 Using Razor syntax (Views\Shared\DisplayTemplates\Boolean.cshtml):
@{ Layout = null; }
@(ViewData.Model ? "Sim" : "Não")
How about just this simple thing:
@((bool)item.Ativo ? "Yes" : "No")
you can extend HtmlHelper for bool.
and remember you must use direction YesNoExtensions namespace on razor page . rem:we can overload DisplayFor for boolean with change function sign.
public namespace SampleExtensions
{
public static class YesNoExtensions
{
public static MvcHtmlString DisplayFor<TModel, TValue>(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression, bool flag = true)
{
object o = expression.Compile().Invoke(html.ViewData.Model);
if (o.GetType() == typeof(bool))
{
if ((bool)o)
return new MvcHtmlString("Yes");
else
return new MvcHtmlString("No");
}
return DisplayFor(html, expression);
}
}
}
and razor page.
<%@ import namespace='SampleExtensions' %>
<%: Html.DisplayFor(model => model.SomeBoolean, true)%>
last parameter true is dummy for select right DisplayFor which has been overload by us. I hope usefull.
This is an old post, but I was having trouble finding a current answer.
There's actually an @HTML method in MVC 5, @Html.Display**Text**For(model => model.SomeBoolean)
.
