Datagrid multiselect with conditional formatting not as expected

I would like to use the datagrid with multiselect with conditional formatting but it is not working as I expect. Currently, the conditional formatting only shows up on hover and when it shows it doesn't seem to be the actual color but some sort of blended color. I would like the conditional formatting to show when the grid is displayed and not only on hover.

I'm wondering if I'm not linking the css in the right way. I don't know if I should link to standard.css or standard-base.css. This older post shows link to both standard.css and standard-base.css but you're getting starting documentation it links to the base css only.

Here are the files that show the behavior I'm describing with conditional formatting showing on hover only:

Hi @Enola,

Do you want to override the built-in selection styling of RadzenDataGrid with the custom formatting? You may need to handle the CellRender event instead of RowRender or try applying the CSS !important modifier :

args.Attributes.Add("style", $"background-color: {(args.Data.EmployeeID == 1 ? "yellow !important" : "white")};"); }
