    checking for empty property in v6 Razor

    Hi,

    I'm working on my first Umbraco MVC project, so it's all a bit new to me.

    In my Partial View Macro, I try to check if a value for a property is set like this:

    @if(!Model.Content.IsNull("memberEmail"))

                        {

                          <li>

                            <i class="icon-envelope-alt"></i>

                            <a href="mailto:@Model.Content.GetPropertyValue("memberEmail")">@Model.Content.GetPropertyValue("memberEmail")</a>

                          </li>

                        }

     

    But this is not working, I'm getting an invalid cast error.

    I checked the v6 Razor Cheatsheet and it gives this method for property checking:

    .IsNull(string PropertyAlias)

    So I'm not sure why the above code is not working.

    Thanks for your help,

    Anthony

    Hi Anthony,

    You should use HasValue, e.g

    @if(Model.Content.HasValue("memberEmail"))

    Thanks,

    Hi Jeavon,

    Thanks a lot, that's pretty simple. I previously tried the HasPropery() method, but that hadn't the result I was looking for, as that method only checks if a doctype has a the given property, not if it's empty.

    greetings,

    Anthony

    Hi Anthony,

    No worries, if you want to be really safe you can do

    @if(Model.Content.HasProperty("memberEmail") && Model.Content.HasValue("memberEmail"))

    Thanks,

    Jeavon
