Im using @await Html.GetBlockGridItemAreasHtmlAsync(Model) to render some nested blockgrid. How do i null check this to see if the current block has child blocks? It works fine as it is in the frontend, but i get an error in the backoffice custom view when inserting a block that i empty (and therefor unable to add children inside it).

If I remember right,

Model

in this context is an

Enumerable

type under the hood so you can do something like

if (Model != null)

or

if (Model.Any())

Well Hello mr. Butterfield 🙂 im actually using your package for backoffice previews

There may be a property on Model then! Such as

Model.Areas

or

Model.Blocks

Strange... I left it over the weekend, not working when i left it. But now @if (Model != null){ works... I guess a rebuild was in order 🙂

My favorite is @if(Model?.Any() == true){ ... }

Rather make a extension method like

Model.NotNullAndHasAny()

or something 😛

in Areas.chtml.. I have

if (Model?.Areas.Any() != true) { return; }

for an early exit.. Which I think, if memory serves, also covers Areas without a Block too? 🤔 Or

if (Model?.Areas.Any(x=>x.Any()) != true) { return; }

?? (for if you allow layouts in areas too)? To get an actual block in an area had to use..

var x = item.Areas.FirstOrDefault(x => x.Any(y => y.Content.ContentType.Alias == GridShowMore.ModelTypeAlias));
