    Simple show/hide if property has value

    I thought this would be "simple"... Being new to Razor/Umbraco 7, I am looking at the Umbraco Razor Cheatsheet (ver. 6?) and trying to make sense of it all... but alas...

    On my frontpage I would like to have a div show if a property from my frontpage doc type has a value:

    @{
    var getInfo = Model.Content.GetPropertyValue("frontpageInfo");
    if (getInfo != null )
    {
        <div class="container" style="color: #fff; background: #f00;">
            @getInfo <p>read more here...</p>
        </div>
    }
}

    The div shows no matter if property has value or not... What am I missing?

    Hi and welcome :)

    Did you debug and check the value after GetPropertyValue? I think that your variable will have an empty string set'ed by GetPropertyValue.

    Do the compare like: !String.IsNullOrWhiteSpace([your_variable])

    :)

    Hi Bent

    If you use the checkbox (true/false) property editor, the property will most likely always contains a value (0 or 1 in the published xml cache).

    You can cast the property to a boolean and then compare against true or false, e.g.

    @{
    var getInfo = Model.Content.GetPropertyValue<bool>("frontpageInfo");
    if (getInfo == true)
    {
        <div class="container" style="color: #fff; background: #f00;">
            @getInfo <p>read more here...</p>
        </div>
    }
}

    or if it is a string property cast the property as a string.

    @{
    var getInfo = Model.Content.GetPropertyValue<string>("frontpageInfo");
    if (!string.IsNullOrWhiteSpace(getInfo))
    {
        <div class="container" style="color: #fff; background: #f00;">
            @getInfo <p>read more here...</p>
        </div>
    }
}

    Ok great!... That was a solution...

    So is ther also <int>, <float> etc?

    Cheers!

    Yes, you can also cast to other types like <int>, <float>, <decimal>, <DateTime> etc. and choose the ideal type depending on the datatype you are using.
