Angular Data Gridv32 Themes: Customising Selections

Control how selected rows and cells appear.

This page describes the grid's theming system from v32 and before, for the benefit of applications that have not yet migrated to the Theming API. These themes are deprecated and will be removed in a future major version. You may want to visit the new theming docs or check out the migration guide.

Row Selections

When row selection is enabled, you can set the color of selected rows using --ag-selected-row-background-color. If your grid uses alternating row colours we recommend setting this to a semi-transparent colour so that the alternating row colours are visible below it.

.ag-theme-quartz {
    /* bright green, 10% opacity */
    --ag-selected-row-background-color: rgb(0, 255, 0, 0.1);
}

Cell Selections

Cell selections can be created by clicking and dragging on the grid. Multiple overlapping range selections can be made by holding ^ Ctrl while creating a new range outside the existing range. Copying from a selection will briefly highlight the range of cells (Ctrl + C). There are several variables to control the selection and highlight style:

.ag-theme-quartz {
    --ag-range-selection-border-color: rgb(193, 0, 97);
    --ag-range-selection-border-style: dashed;
    --ag-range-selection-background-color: rgb(255, 0, 128, 0.1);
    /* these next 3 variables control the background colour when 2, 3 or 4+ ranges overlap,
       and should have progressively greater opacity to look realistic - see the docs below
       for the correct formulas to use */
    --ag-range-selection-background-color-2: rgb(255, 0, 128, 0.19);
    --ag-range-selection-background-color-3: rgb(255, 0, 128, 0.27);
    --ag-range-selection-background-color-4: rgb(255, 0, 128, 0.34);

    --ag-range-selection-highlight-color: rgb(60, 188, 0, 0.3);
}
