How do you set the height of a Vaadin 8 Grid to be undefined?

Question

I've tried both Grid.setUndefined() and Grid.setHeight("-1px") and neither works. They should both be doing the same but if my grid only has say 3 items then the bottom of the grid is empty and the height is significantly taller than 3 rows.

Are you adding Grid component with expanding? – Dawid Fieluba Dec 04 '17 at 15:07 — Dawid Fieluba, Dec 04 '17 at 15:07

Try setHeightByRows method (Java doc).

That's exactly what I did but the last row was a bit truncated. However it's good enough for now. – Stephane Grenier Dec 13 '17 at 04:40

Here is my proposition for workaround:

grid.getDataProvider().addDataProviderListener( dataProviderEvent ->
                grid.setHeightByRows( grid.getDataProvider().size( new Query() ) ) 
);

Your solution work great, But you should check the size of your datas. It should be more than zero rows, otherwise it will return error. – Mankeomorakort Jan 28 '19 at 10:42

Set the grid HeightMode to UNDEFINED:

grid.setHeightMode(HeightMode.UNDEFINED);
