Suppress validation attributes for Razor Pages property

Question

MyPage.cshtml.cs

[ValidateNever]                            // <-----
public string ProductName { get; set; }

MyPage.cshtml

<input asp-for=@Model.ProductName />

That renders:

<input type="text" data-val="true" data-val-required="The ProductName field is required." id="ProductName" name="ProductName" value="">

I expected [ValidateNever] would suppress validation attributes, but they are emitted anyway.

How can I suppress them?

Answer 1

From .NET 6+ the non-nullable property must be required, otherwise the ModelState will be invalid.

The easist way, change your code like below:

[ValidateNever]                            // <-----
public string? ProductName { get; set; }
