I am working on a C# E-Commerce application.

I having difficulties deleting and adding a item to the cart. It gives me the error in the price column which is a decimal field.

The application only executes the delete/add to cart when I change this decimal value to a normal integer value without decimals.

How can I change the Detail.cshtml file to counter this issue?

Please view the links for the 2 images below:

What I have tried:

I have tried editing validation in the Detail.cshtml. I have also changed the Price field in the Detail.cshtml to editable to test whether the normal number can be used.

I have looked briefly at the code image you provided and didn't see any JavaScript, so I'm not sure if this suggestion will make sense. However, it is a common technique to use JavaScript to test form input.

This small JS function isMoney uses regex to check for digits then an optional decimal point and then allows 0 to 2 digits after that decimal point.

function isMoney(input) {
    var regex = /^\d+(?:\.\d{0,2})$/;
    return regex.test(input);
}


In the form itself, you call the function and branch accordingly. e.g.

var input = document.getElementById("Price").value;
if (isMoney(input)) {
    // Input is valid
} else {
    // Input is not valid
}


I'm not sure how this suggestion fits into the code style you are using, hopefully it is helpful.
