Web Components Grid Column Selection Overview

    The Web Components Grid Column Selection feature in Ignite UI for Web Components offers a simplified and Excel-like way to select and highlight an entire column with a single click. It can be enabled through the columnSelection input. Thanks to the rich API, the feature allows for easy manipulation of the selection state, data extraction from the selected fractions, data analysis operations, and visualizations.

    Web Components Grid Column Selection Example

    The sample below demonstrates the three types of IgcGridComponent's column selection behavior. Use the column selection dropdown below to enable each of the available selection modes.

    *Contact Title, City and Address columns are with disabled column selection.

    Basic Usage

    The column selection feature can be enabled through the columnSelection input, which takes GridSelectionMode values.

    Interactions

    The default selection mode is None. If set to Single or Multiple, all of the presented columns will be selectable. With that being said, in order to select a column, we just need to click on one, which will mark it as selected. If the column is not selectable, no selection style will be applied on the header, while hovering.

    [!Note] The Multi Column Headers feature does not reflect on the selectable input. The ColumnGroupComponent is selectable, if at least one of its children has the selection behavior enabled. In addition, the component is marked as selected if all of its selectable descendants are selected.

    *Under Country Information Column Group only column City and Postal code are selectable.

    Keyboard Combinations

    [!Note] The keyboard combinations are available only when the grid columnSelection input is set to multiple.

    There are two scenarios for keyboard navigation of the Column Selection feature:

    • Multi-column selection - holding ctrl + click on every selectable header cell.
    • Range column selection - holding shift + click selects all selectable columns in between.

    API Manipulations

    The API provides some additional capabilities when it comes to the non-visible columns such that, every hidden column could be marked as selected by setting the corresponding setter.

    [!Note] The above statement also applies to the ColumnGroupComponent, except that when the selected property is changed it changes the state of its descendants.

    More information regarding the API manipulations could be found in the API References section.

    Styling

    In addition to the predefined themes, the grid could be further customized by setting some of the available CSS properties. In case you would like to change some of the colors, you need to set a class for the grid first:

    <igc-grid class="grid"></igc-grid>

    Then set the related CSS properties to this class:

    .grid {
    --ig-grid-row-selected-background: #0062A3;
    --ig-grid-row-selected-text-color: #ecaa53;
    --ig-grid-row-selected-hover-background: #0062A3;
    --ig-grid-header-selected-text-color: #ecaa53;
    --ig-grid-header-selected-background: #0062A3;
    --ig-grid-row-selected-hover-text-color: #ecaa53;
    --ig-grid-row-selected-hover-background: #0062A3;
}
