asp.net mvc 3 razor change model value in view

I have model with bool property IsMale. In view i have table with values how i can change value?

I tried this:

 <td>
            @if (item.IsMale == true)
            {
                @Html.DisplayFor(modelItem => "Male")
            }
            else
            {
               @Html.DisplayFor(modelItem => "Female")
            }
        </td>

But im getting error:

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

And in create view how i can make radio buttons >Male >Female and return it in bool?

@Html.DisplayFor takes a property of the model and outputs the value of that property. What you are trying to do is printing a hardcoded string. You don't need DisplayFor for that. Just try:

<td>
    @if (item.IsMale)
    {
        <text>Male</text>
    }
    else
    {
        <text>Female</text>
    }
</td>

A better design would be if you don't make the gender a boolean value. You may want to add "Unspecified" or whatever later. If you make the gender a "first class" entity, the names "male" vs. "female" as well as the radio buttons don't have to be hardcoded:

Say you have a class called "Gender" with a property "Name". Your modelItem would then have a property "Gender" with is an object of type "Gender".

<td>@Html.DisplayFor(modelItem => modelItem.Gender.Name)</td>

and for the radios you could retrieve the whole list of available genders from your data source and put them as a RadioButtonList into the ViewModel. Then you can simply use:

@Html.RadioButtonListFor(modelItem => modelItem.AllGenders)

Perhaps you could use something like this:

@Html.CheckBoxFor(model => model.IsMale)

I see that it is a radio button you want...

@Html.RadioButtonFor(model => model.IsMale, true)

@Html.RadioButtonFor(model => model.IsMale, false)
