    Simple razr if statement

    Hi everyone,

    I'm trying to run a simple if test in Razr, but I'm not familiar with the language so wondered if anyone could help.

    What I'm looking to do is the following:

    If a field is empty, don't display it - simple right!

     

    Here's what I have so far, but I don't know where to start as I'm getting a runtime error..

    <umbraco:Macro runat="server" language="cshtml">
    @if(Model.GetProperty("heading").Value!=String.Empty){
       <h1><umbraco:Item field="heading" runat="server" /></h1>
    }
    </umbraco:Macro>

     

    Any help would be much appreciated!

     

    Thanks,

    Tom

    Hi Tom

    Give this a try:

    <umbraco:Macro runat="server" language="cshtml">

@if(Model.HasValue("heading")){
   <h1>@Model.heading</h1>
}
</umbraco:Macro>

    Perfect thanks a lot!

    So is the hasvalue statement a shorthand for checking if something exists in the page as it's being built?

    Could anyone recommend a good solid starting place to learn Razr too?

     

    Thanks!

    Tom

    Hi Tom,

    A goog starting point could be:

    http://our.umbraco.org/documentation/Reference/Templating/Macros/Razor/basic-razor-syntax

    http://our.umbraco.org/documentation/reference/templating/macros/razor

    And the Umbraco TV.

    http://umbraco.tv/

    The documentation for working with some you the dbuilt-in-property-editors:

    http://our.umbraco.org/documentation/using-umbraco/backoffice-overview/property-editors/built-in-property-editors/

    Hope this can helps you and of course keep asking in the forum.

    /Dennis

    Hi Tom,

    Yes, to be really really sure you can do this which will first check the property exists and then check if it has a value

    @if(Model.HasProperty("heading") && Model.HasValue("heading")){
   <h1>@Model.heading</h1>
}

    Are you just starting out with this project/Umbraco? If you are, I would recommend that you use Mvc templating rather than WebForms? The DynamicNode object you are using here (Model) is now legacy and has been fully replaced by IPublishedContent/UmbracoHelper either native in Mvc views or using a Partial View Macro with a WebForms (.master) template.

    I would also recommend umbraco.tv as Dennis has above.
