Кажется, проблема была в том, чтобы испортить input
и обернуть div
идентификаторы.
HTML
<div class="form-group row">
@Html.Label("Finish", new { @class = "col-sm-2 col-form-label", @for = "TimeStart2" })
<div class="col-sm-10">
<div class="form-group">
<div class="input-group date" id="datetimepicker1" data-target-input="nearest">
<input id="TimeEnd" name="TimeEnd" value="@Model.TimeEnd" type="text" class="form-control form-control-sm datetimepicker-input" data-target="#datetimepicker1" />
<div class="input-group-append" data-target="#datetimepicker1" data-toggle="datetimepicker">
<div class="input-group-text"><i class="fa fa-calendar"></i></div>
</div>
</div>
</div>
</div>
</div>
JS
$(document).ready(function () {
$('#datetimepicker1').datetimepicker({
locale: 'es'
});
});
