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.
@Html.DisplayTextFor(model => model.SomeBoolean)
.
Use the in-built DisplayTextFor() instead on DisplayFor().
This is an old post, but I was having trouble finding a current answer.
For true/false use DisplayTextFor by Justin Grant
For yup/nope based on Nuri YILMAZ, this is .NetCore 2.2, to downgrade replace HtmlString with MvcHtmlString:
1) C# write new extension DisplayForYZ
public namespace X.Views.Shared
{
public static class DisplayExtensions
{
// If this was called DisplayFor not DisplayForYZ, we'd get recursion
public static IHtmlContent DisplayForYZ<TModel, TValue>
(this HtmlHelper<TModel> html, Expression<Func<TModel, TValue>> expression)
where TModel : Y
{
object o = expression.Compile().Invoke(html.ViewData.Model);
// For any bool on TModel, return in this custom way:
if (o.GetType() == typeof(bool))
{
return (bool)o ? new HtmlString("Yup") : new HtmlString("Nope");
}
// Otherwise use default behaviour
return html.DisplayFor(expression);
}
}
}
2) cshtml: Import the DisplayExtensions
namespace and use new extension.
@model X.ViewModels.Y
@using X.Views.Shared;
@Html.DisplayForYZ(modelItem => modelItem.Z) @*//Yup/Nope*@
@Html.DisplayForYZ(modelItem => modelItem.A) @*//default non bool behavior*@
@Html.DisplayFor(modelItem => modelItem.Z) @*//check box*@
@Html.DisplayTextFor(modelItem => modelItem.Z) @*//true/false*@
X = {my company} Y = {object for customised display} Z= {bool property} A= {non-bool property}

Thanks, this worked great! – Lorgnon
