How to access current column for onBeforeRowHeaderDomAdd?

Asked by andy

Hello,

When we provide multiple columns for left sidebar, ie:

rowHeaderColumns: [{ id: firstColumn }, { id:  secondColumn }]

Is there a way to access which column are we rendering row header’s content for?

While not obvious, it seems like `args.x` is the current column index being rendered.

Hi Andy,

Yes, args.x is the column index.

However, I recommend using onBeforeRowHeaderRender instead when possible (you can access the header cell properties using args.rows.columns[] there). The onBeforeRowHeaderDomAdd should be only used if you really need access to the DOM element.

Hi Dan,

Thanks for the response. We are intentionally using `onBeforeRowHeaderDomAdd` to render JSX with styled-components, since a lot of our reusable components is using this library.

Is `args.x` an official flag, or is it likely changed in the future?

Thanks for the update. For rendering JSX, there is no other option.

The args.x property is official, and you can rely on it in the future.
