What is DataAnnotations in mvc?

Anonymous User 2262 09-Oct-2014
Here is a class "Cars" and I have 2 attributs (min/max CO2).
public class Cars
        {
            [Range("MinCO2", int.MaxValue, ErrorMessage = "MaxCO2 < MinCO2")]
            public int MaxCO2 { get; set; }
            [Range(0, "MaxCO2", ErrorMessage = "MaxCO2 > MinCO2")]
            public int MinCO2 { get; set; }
        }

I use the Data Annotation 'Range' to fix the minimum and the maximum value.

But I want to use the car's attribut to fix the minimum or the maximum value.

Or if there is another solution with jQuery, it can be possible.

Try this

Send Mininum value and Maximum value from Controller to View using Model or ViewBag/ViewData.

ViewBag.Min = 0;
ViewBag.Max = Int32.MaxValue;


In View use jQuery validation to specify min and max validation using passed values. View.

<script language="javascript">
    var mi="@ViewBag.Min";
    var mx="@ViewBag.Max";
    $(document).ready(function(){
        $('#myform').validate({
            rules:{
                field:{
                    required: true,
                    min: mi,
                    max:mx,
                }
            };
        });
    });
</script>
