Answer 1

You need to add an event handler for the formatItem event of FlexGrid and then iterate over all the rows and set their cssClass property.

JS:

grid.formatItem.addHandler((s, e) => {
    s.rows.forEach(r => {
        r.cssClass = 'custom-back';
    })
});

CSS:

.custom-back {
  background: rgb(18, 148, 148) !important;
}
