Here is my DiscountRate variable in my model.
public decimal DiscountRate { get; set; }
Here is my input in view.
@Html.TextBoxFor(x=>x.DiscountRate, new { @class = "form-control", @type = "number", step = "0.01", @placeholder = "0.00", @min="0", @max="100" })
The problem is when I enter a value (2,50 or 2.50 etc.) I catch it in my Controller like 250. What is the problem here?
>Solution :
Your issue stems from the HTML5 type="number" input not correctly handling dot . and comma , in different browsers and culture settings. As a result, when you enter 2,50 or 2.50, it is sent to the server as 250.
To fix this, change the input type to text and handle the validation on the server side:
@Html.TextBoxFor(x => x.DiscountRate, new { @class = "form-control", @placeholder = "0.00" })
Also, ensure that your application’s culture settings are configured properly:
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-US");
Yes, you can continue using the "number" property, but you’ll need to make some adjustments. This is important because decimal separators vary between cultures.
One solution is to add the lang and step attributes to your input element. By setting the lang attribute to "en", you ensure that the decimal separator is a dot .:
@Html.TextBoxFor(x => x.DiscountRate, new { @class = "form-control", @type = "number", @lang = "en", step = "0.01", @placeholder = "0.00", @min = "0", @max = "100" })
Additionally, you can use JavaScript on the client side to replace comma , with dot .:
<script>
document.getElementById("DiscountRate").addEventListener("input", function (e) {
this.value = this.value.replace(',', '.');
});
</script>
This way, regardless of whether the user enters a comma or a dot, the value will be transmitted correctly.
