    Checking if a field is null.

    Hello Everyone,

     

    I am trying to test to see if a user has left a certain field null. If they have then i will render one of the other fields as below:

    @if(@Umbraco.Field("Field1"){

    do this

    else{

    do this

    }

     

    I cant test using @RenderLinkIfNotEmpty. And when i look at the cheat sheet is shows .IsNull(property Alias).

     

    What is the best way for me to achieve this?

     

    Kind regards.

    Hi James,

    I assume that you are doing this directly in the template and not a in partial view maco.

    Try this:

    @if (string.IsNullOrWhiteSpace(CurrentPage.Field1) == false){
        do this
    }else{
        do this
    }

    If my assumption is wrong, do not hesitate to write again

    Hope this helps,

    /Dennis

    How about

    @if (CurrentPage.HasValue("Field1")){
        <p>it's not null or empty</p>
    }else{ 
        <p>it's null or empty</p>
    }

    Hi James,

    That is great to hear.

    @Jeavon: I was just using the syntax from the Txt Starter Kit,

    @James, As you can see in Umbraco you can do things in several ways.
