Checking if a MACRO gives output

Templates, (partial) views and macros

Umbraco 7
Hello guys,

I was wondering if there was any way to check if a certain macro gives an output like so:
```
@if(Model.Content.HasValue("expertBijBlog")){
    <div class="hidden-xs hidden-sm hidden-md col-lg-3"><h3>Expert:</h3></div>
}else if(MACRO HAS VALUE){
    <div class="hidden-xs hidden-sm hidden-md col-lg-3"><h3>Gerelateerd:</h3></div>
}
```
Could anyone help me out?

Thanks,

~Lex

Hi Lex

You can use RenderMacro method and then check if there some data after rendering, but it's not a good idea. Like that:

var macroOutput = Umbraco.RenderMacro("myMacroAlias");

@if(Model.Content.HasValue("expertBijBlog")){
    <div class="hidden-xs hidden-sm hidden-md col-lg-3"><h3>Expert:</h3></div>
}else if(!string.IsNullOrEmpty(macroOutput)){
    <div class="hidden-xs hidden-sm hidden-md col-lg-3"><h3>Gerelateerd:</h3></div>
}

Thanks,

Alex

Hi Alex,

I was quite busy and completely forgot about this post. I just looked at your solution and it works, except for a minor detail i added:

            @{
                var macroOutput = Umbraco.RenderMacro("Macro");

                if(Model.Content.HasValue("Valuefield")){
                    <div class="hidden-xs hidden-sm hidden-md col-lg-3"><h3>Do this:</h3></div>
                }else if(!string.IsNullOrEmpty(macroOutput.ToString())){
                    <div class="hidden-xs hidden-sm hidden-md col-lg-3"><h3>Do That:</h3></div>
                }
            }
