Question

I was wondering how I could do this Boolean check. I’m not very good with mvc3 Views…

Error 1 Cannot convert lambda expression to type ‘bool’ because it is not a delegate type

@model Project.Domain.Worker //active is a value in worker  
@if (model => model.active == true) {  //this doesn't work 
        <div class="editor-label">
            @Html.LabelFor(model => model.param)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.param)
            @Html.ValidationMessageFor(model => model.param)
        </div>
}    

Answer 1

Since model.active is a boolean, you can simply do:

@if (Model.active)

When dealing with boolean types, you never need to compare them to true or false.

Your confusion may arise from HTML helpers taking a lambda – an if cannot take a lambda.
