Grid Styling - Overwrite style of ag-grid

Question

I have the following style:

.ag-theme-fresh .ag-row-selected {
    background-color: #bde2e5; 
}`

It comes from a css style file of a theme. But I want to overwrite it with this style:

.ag-theme-fresh .ag-row-even .ag-row-selected {
  background-color: #1428df;
}

But it has not effect and my component uses the first style. How can I overwrite the first style 1? I tried with !important but it does nothing.

Should I define my custom style at the beginning of the css file?

UPDATE:

I found I can use the function gridOptions.getRowClass to set the style class to be used. But I would like to solve the issue central (for all the angular grids that I use in my application). Any idea?

Answer 1

You should use ViewEncapsulation

Just add to your component encapsulation: ViewEncapsulation.None:

import { Component, ViewEncapsulation } from "@angular/core";

@Component({
    selector: '....',
    templateUrl: '....',
    styles: [`
        .ag-theme-fresh .ag-row-selected {
            background-color: #1428df !important;
        }
    `],
    encapsulation: ViewEncapsulation.None
})

Answer 2

To override the ag-grid use you need to use ng-deep as the style defined in angular component do not overide ag-grid css

:host ::ng-deep .ag-header-cell-label {
  justify-content: center;
}

update : this will make the style global. By changing the encapsulation set as none (ViewEncapsulation.None) at component will make style global as well.

if you are using sass or scss you could override in the style.scss/sass. this would be applicable at all places

@import "../node_modules/ag-grid-enterprise/dist/styles/ag-grid.scss";
@import "../node_modules/ag-grid-enterprise/dist/styles/ag-theme-alpine/sass/ag-theme-alpine-mixin";

.ag-theme-alpine {
  @include ag-theme-alpine(
    (
      // use theme parameters where possible
        alpine-active-color: #c066b2,
    )
  );
    .ag-header-cell-label {
        justify-content: center;
      }
    }

if you have need of doing at a specific grid, prefer custom class and make sub-class for the ag-grid.
