Hi, it should work without problems. Maybe the hidden template you are using is your custom one, and e.g. overrides the default name of the field?
The output HTML, for this chkRuhendmeldungVorhanden field, should be reassembled into this:
<input
name="chkRuhendmeldungVorhanden"
type="hidden"
...
Check the web console output for any warnings.
If you have some time provide me please self-contained, minimal, reproducible test case so I can help you.
Hi,
I use:
@Html.HiddenFor(model => model.chkRuhendmeldungVorhanden, new { htmlAttributes = new { @class = "form-control" } })
and this code creates:
might be a problem that this is a hidden Input with data-val=true and Value=False instead of a checkbox?

Your message seems to be incomplete, please use GitHub instead of direct reply:
found it - in Javascript I have to use $('#chkRuhendmeldungVorhanden').val(true); to assign a value to the field...

Ok, so your chkRuhendmeldungVorhanden
property is of Nullable<bool>
type. When uninitialized, it is interpreted as null
. The result of the expression null == true
is always false
since a value of type bool
is never equal to null
of type bool?
.
Instead of setting the field value in JS you can initialize the model before sending to client.
It has nothing to do with the visibility of the control.
Thank you…

Hello, is it possible to add validation on a Datetime field which is based on a Checkbox Value (chkRuhendmeldungVorhanden) of a hidden field?
[RequiredIf("chkRuhendmeldungVorhanden == true", ErrorMessage = "Sie müssen ein Wiederbetriebsdatum eingeben.")] public DateTime? Personenbetreuer_Wiederbetriebsdatum1 { get; set; }
if the checkbox "chkRuhendmeldungVorhanden" is visible it works but if I set it to hidden it doesn't work: @Html.HiddenFor(model => model.chkRuhendmeldungVorhanden, new { htmlAttributes = new { @class = "form-control" } })
