Hi,

Im trying to check if a page node existing when using the content picker data type. So if a page is deleted, then the link is not outputted.

Any help would be grateful.

<div>
    @Umbraco.Field(Model, "callToActionContent")

    @if(Model.HasValue("callToActionButtonLink")){
        var button = Model.GetPropertyValue<IPublishedContent>("callToActionButtonLink");
        <div class="btn">
            <a href="@button.Url">Contact &raquo;</a>

Hi Martin i think you should do something like this

 @inherits Umbraco.Web.Mvc.UmbracoViewPage

<div>
@{
      var button = Model.GetPropertyValue<IPublishedContent("callToActionButtonLink");
 }

  @if(button != null){
        <div class="btn">
            <a href="@button.Url">Contact &raquo;</a>
        </div>  
    }
</div>
