am trying to create filters like in eCommerce website like Amazon, Flipkart.

I have created primary tables for all filters as below.

SQL

create table Work
(
id int identity(1,1) Primary Key Not Null,
work_name varchar(30) Not Null,
isSelected bit Default(0),
created_date Datetime default(GETDATE())
)

Now I want to create a CheckBox List so that a user can filter the products according to the selected details.

What I have tried:

I have created an Editor Template

C#

@model API.Models.Work

@Html.HiddenFor(x=>x.id)
@Html.HiddenFor(x => x.work_name)
@Html.CheckBoxFor(x=>(bool)x.isSelected)    
@Html.DisplayFor(x=>x.work_name)

I am using the template as

C#

@model IEnumerable<API.Models.Work>

@Html.EditorForModel()

I get the below error

An exception of type 'System.InvalidOperationException' occurred in System.Web.Mvc.dll but was not handled in user code

Additional information: Templates can be used only with field access, property access, single-dimension array index, or single-parameter custom indexer expressions.

You might need to create a new model class for the data that allows IsSelected to be a bool rather than a bit then copy the data from your table into that class and use that class as the view model.

In your template try

C#

@{
var convertedIsSelector = (bool)Model.isSelected
}
@Html.CheckBoxFor(x => convertedIsSelector)

instead of

C#

@Html.CheckBoxFor(x=>(bool)x.isSelected)

Not sure whether you need to cast to bool explictly at all.
Also friendly advice. Please note that some of your properties use underscores and some camel case. So unaesthetic.
