I have tried this : @Html.GetGridHtml(Model, "gridBox") & this too @await Html.GetBlockGridHtmlAsync(Model.grid) which is right in umbraco 12? If possible please provide snippet with correct namespaces & nuGet packages (if any needed!). @Sebastiaan

Think you are confusing the

Legacy Grid

and the new

Block Grid

.. which are you using? (it's not clear from `Grid Box Layout `as that's not something I think is in the core) https://docs.umbraco.com/umbraco-cms/fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/grid-layout vs https://docs.umbraco.com/umbraco-cms/fundamentals/backoffice/property-editors/built-in-umbraco-property-editors/block-editor/block-grid-editor as the two methods you mention are for the two different propeditor rendering. There's full documentation for both at the links above. 😉

Thanks Mike for the answer, yes I am talking about Block Grid, I confused on block grid layout stylesheet , I will again have a look on it. Whether to reuse default block grid layout stylesheet or should upload new custom one.
