    Model.HasValue

    Umbraco 10.1.0

    Am I missing something simple here? The first if doesn't work but the second one does on this textBox property.

            @if (Model.HasValue(Model.WelcomeBoxTitle))
            {
                <h1>@Model.WelcomeBoxTitle (1)</h1>
            }
    
            @if (Model.HasValue("welcomeBoxTitle"))
            {
                <h1>@Model.WelcomeBoxTitle (2)</h1>
            }

    the second one is correct since the HasValue is to check if the property exists on the IPublishedContent and expects the property alias

    Ah I see.

    Is there a way then to check if a property has content using the models builder version?

    HasValue will return false if the property itself is empty.

    sorry for confusion, my first comment was not 100% accurate.

    so @if (Model.HasValue("welcomeBoxTitle")) will be false if the property does not exist or is empty

    Yes, that one works for me, but this one always returns false regardless i.e if there is content in the property or not.

    @if (Model.HasValue(Model.WelcomeBoxTitle))
            {
                <h1>@Model.WelcomeBoxTitle (1)</h1>
            }

    That is because Model.WelcomeBoxTitle is not the property alias, and hasvalue requires the property alias
