Question

I am very new to .NET and am using MVC 4. I have a variable “AvgAnnualGrowth” of type double. This variable can have positive or negative values. When it is negative, I should display “-” before the data and when its positive, I should display “+” before the data. There is no problem with the negative data as the double variable displays “-” by default. For positive values, it does not display “+” explicitly. Any ideas on how to concatenate “+” in front of the data?

Following is the code snippet from my (view) cshtml file.

@foreach (var item in Model)
{

    <tr>                
        <td align="right">                    
            @Html.DisplayFor(modelItem => item.AvgAnnualGrowth)
        </td>   
    </tr>
}

Answer 1
