How to set the textbox border color red when validation fails

Question

I have got a task to set red color border for text box when the validation fails in .net mvc 4.

BExtensionMethods.cs

    public static string GetTextBoxColor(this ModelStateDictionary ModelState)
    {
        string textBoxColor = string.Empty;
        int count = 1;
        var errorKeys = (from item in ModelState
                         where item.Value.Errors.Any()
                         select item.Key).ToList();
        foreach (var item in errorKeys)
        {
            textBoxColor += string.Format("{0}.{1}</br>", count, item);
            count++;
        }
        return textBoxColor;
    }

Here the json object contains the values.How can I filter it?

Did you try setting the red color where you are calling alert? — Ashwin Singh, Apr 24 '13 at 07:50
Json can directly be converted to javascript objects which you can use to get the value. http://www.w3schools.com/json/json_eval.asp — Ashwin Singh, Apr 24 '13 at 07:58

if ($('#TextBoxID').val() == '') {
    $('#TextBoxID').css('border-color', 'red');
}
else {
    $('#TextBoxID').css('border-color', '');
}

You need to make a css class like that:

.errorClass { border:  1px solid red; }

And add it to your textbox whith jQuery:

$("#myTextBox").addClass('errorClass');

If you have only one textbox and id is known to you , you can use the @PanzerKadaver solution. Otherwise i would suggest to return in the json it self the ids of the textboxes which you want to make the red . Then loop through it and add the error class on the client side.

My all data comes under this variable- objRenewableEnergy.How can I filter the values from objRenewableEnergy – Nithin Viswanathan Apr 24 '13 at 08:12
use can use the json notation result.renewableEnergy and loop through it. In case you want to see the exact JSON , using the developer tool of the IE using F12 and see the structure of the JSON coming with all the properties. You can loop usin $.each of the jquery – Devesh Apr 24 '13 at 08:15
for (var n = 0; n < objRenewableEnergy;n++ ) { } is it correct? – Nithin Viswanathan Apr 24 '13 at 08:36

result.renewableEnergy will give you the value you need. Any other properties of the objRenewableEnergy can be accessed by result.renewableEnergy.property

Is its a list or a collection you can use for loop to access values and find the one you need. for(var n in result.renewableEnergy.values){} – Ashwin Singh Apr 24 '13 at 08:19
for (var n = 0; n < objRenewableEnergy;n++ ) { } is it correct? – Nithin Viswanathan Apr 24 '13 at 08:31
