Hi Ludtwigk,
>I have tried things like disabled="@Model.Disabled" or disabled="@Model.Disabled ? "disable" : null)" but none of that works. The condition can change multiple times. Is there a way to achieve this?
For you set the Disabled=true in your C# code,so when you firstly render the razor pages,the select field should be disabled.Because this code `(@Model.Disabled ? "disable" : null)` means the data should be `disable` when Disabled= true and the data
should be null when Disable = false.
From the docs(https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.remoteattribute?view=aspnetcore-3.1),you need
to know that remote validation configures Unobtrusive validation to send an
Ajax request to the web site. The invoked handler should return JSON indicating whether the value is valid.So it could not change the value when you return page because it is a validation with ajax.
Custom validation js like below:
Index.cshtml:
@page
@model IndexModel
<form method="post" id="Test">
<input asp-for="Name" />
<fieldset>
<select id="patchday" required @(Model.Disabled ? "disabled" : "" )>
<option value="" selected>Patchday</option>
<option value="">aaaa</option>
</select><br />
</fieldset>
<input type="submit" value="submit" />
</form>
@section Scripts {
@{await Html.RenderPartialAsync("_ValidationScriptsPartial");}
<script>
$(document).ready(function(){
$('#Name').change(function () {
$("#Test").validate().element("#Name");
});
$('#Test').validate({
rules: {
Name: {
remote: {
url: "/Index?handler=CheckName",
headers: { 'RequestVerificationToken': $('input:hidden[name="__RequestVerificationToken"]').val() },
type: "post",
success: function (data) {
if (data == false) {
$('#patchday').removeAttr("disabled");
}
}
},
},
}
});
});
</script>
}
Index.cshtml.cs:
public class IndexModel : PageModel
{
//[PageRemote(AdditionalFields = "__RequestVerificationToken",HttpMethod = "post",PageHandler = "CheckName")]
[BindProperty]
public string Name { get; set; }
public bool Disabled { get; set; } = true;
public void OnGet()
{
}
public IActionResult OnPostCheckName()
{
var stage = GetStage();
// Check Stage for Patchday Dropdown
if (stage.Equals("Produktion")){
Disabled = false;
return new JsonResult(false);
}
return new JsonResult(true);
}
}
Best Regards,
Rena
